The speaker system contains no user-serviceable parts. If it should appear to be malfunctioning or damaged, discontinue use immediately and have it inspected by qualified NEXO service personnel. Water exposure: Do not expose the speaker system to direct rain, do not use it near water or in wet conditions. Do not place containers with liquid on speaker system as they might spill into openings. If any liquid such as water seeps into the speaker system, have it inspected by qualified NEXO personnel. Sun exposure: Do not expose the speaker system to direct sun. Operating temperature with temperate climate: 0°C to +40°C (-20°C to +60°C for storage). SYSTEM DEPLOYMENT SAFETY RULES Read User Manual before deployment. Before use of enclosed speaker system, please ensure that anyone involved in system deployment understands the rigging – stacking – pole mounting safety rules as described in the speaker system User Manual. Failure to do this exposes people to potential injury or death. Please check the web site www.nexo-sa.com for the latest update. Always consult qualified NEXO personnel if the device installation requires construction work and make sure to observe the following precautions: Mounting precautions - choose mounting hardware and an installation location that can support 4 times the weight of the speaker system; - do not use speaker system handles for suspended installation; - do not expose speaker system to excessive dust or vibration, or extreme cold or heat to prevent possibility of component damage; - do not place the speaker system in an unstable position from which it might fall accidentally; - if speaker systems uses a stand, ensure that stand specifications are adapted, and that stand height does not exceed 1.40m/55”; never move the stand while the speaker is in position. Connection and powering precautions - remove all connected cables before moving the speaker system; - turn off AC power of all power amplifier units before connecting the speaker system; - when turning on the AC power to the audio system, always turn on the power amplifier last; when turning the AC power off, always turn off the power amplifier first; - when used in cold conditions, a gradual power ramp up should applied to the system on an 5 mn period to allow the loudspeaker components to stabilize during the very first minutes of usage.

..........................................................................................................................................82 Page 8/82 1 INTRODUCTION INTRODUCTION Thank you for selecting a NEXO PS Series equipment. This manual is intended to provide you with necessary and useful information about your PS speaker system, which includes the following products:   LS400 is optional Sub-Bass for PS8  PS8  LS600 is optional Sub-Bass for PS10R2  PS10R2 (available in Left and Right versions)  PS15R2 (available in Left and Right versions)    PS8 Analogue TD Controller (for PS8 and LS400) PS10 Analogue TD Controller (for PS10 and LS600) PS15 Analogue TD Controller (for PS15 and RS15) A full range of accessories that provides safe, flexible and simple means of installing PS Series in fixed installation as well as in touring applications. INTRODUCTION Page 9/82 As for all NEXO systems, PS Series are controlled, powered and monitored by dedicated NEXO TDControllers:  PS analogue TDController provides full control for PS Series and dedicated subwoofers. It has 2 analogue inputs (Left and Right) and 3 analogue outputs (Sub-Bass, PS Left and PS Right);  NX242-ES4 Digital TDController provides comprehensive control of PS loudspeakers in multiple configurations. It allows EthersoundTM digital audio networking, as well as remote control for all units in the network. It has 2 analogue / 4 digital inputs and 4 analogue / 4 digital outputs; IMPORTANT NX242 must be equipped with NX-Tension Card (NX-ES4) to access PS setups  NXAMP4x1 and NXAMP 4x4 are Powered Digital Controllers, providing full control and amplification for PS Series in multiple configurations. Both devices feature 4 analogue inputs and 4 speaker outputs. When equipped with optional card, 4 digital inputs in EthersoundTM digital audio network format as well as remote control for all units in the network become available. For a complete description of these controllers, please refer to User Manuals. The NX242 and NXAMP DSP algorithms and parameters are fixed in software and updated regularly: Please consult the NEXO web site (www.nexo.fr) for the latest software releases. Page 10/82 2 PS GENERAL SET-UP INSTRUCTIONS PS GENERAL SET-UP INSTRUCTIONS 2.1 Speaker connection PS Series connected with Speakon NL4FC plugs (not supplied). A wiring diagram is printed on the connection panel located on the back of each cabinet.The 4 pins of the 2 Speakon sockets identified in / out are connected in parallel within the enclosure. Either connector can be used to connect amplifier or to link to an additional PS range cabinet or to link to an optional Sub (if present). Therefore, a single 4-conductor cable can connect two amplifier channels to various PS and/or dedicated Sub Bass. 2.1.1 PS8 – PS10R2 Connectors are wired as follows: Speakon Connector 1(-) 1(+) 2(-) 2(+) 2.1.2    Not Connected Not Connected PS8/PS10 (-) PS8/PS10 (+) LS400 – LS 600 Connectors are wired as follows: Speakon Connector 1(-) 1(+) 2(-) 2(+) 2.1.3    LS400/LS600 (-) LS400/LS600 (+) Not Connected Not Connected PS15R2 Connectors are wired as follows: Speakon Passive Active Connector Mode Mode Not Connected Not Connected PS15R2 (-)  PS15R2 (+) PS15R2 LF (-) PS15R2 LF (+) PS15R2 HF (-) PS15R2 HF (+) 1(-) 1(+) 2(-) 2(+)    PS GENERAL SET-UP INSTRUCTIONS 2.1.4 Configuring PS15 for Passive or Active Mode  Remove the six TORX screws that hold the connector panel (figure next page);  Remove the connector panel so that filter WAGO connectors become accessible;  In Passive Mode, WAGO connector from filter should be inserted in “Passive In”, and speakers WAGO connectors should be inserted in connector “Passive Out”.  In Active Mode, WAGO Connector from filter should be directly connected into to speakers via speakers WAGO connectors (passive filter is then bypassed). CONNECTOR PANEL 2.1.5 Page 11/82 PASSIVE MODE ACTIVE MODE Cabling NEXO recommends the exclusive use of multi-conductor cables to connect the system: the cable kit is compatible with all the cabinets, and there is no possible confusion between LF, MF and HF sections. Cable choice consists mainly of selecting cables of the correct sectional dimension (size) in relation to the load resistance and the cable length. Too small a cable section will increase both its serial resistance and its capacitance; this reduces the electrical power delivered to the loudspeaker and can also induce response (damping factor) variations. For a serial resistance less or equal to 4% of the load impedance (damping factor = 25), the maximum cable length is given by: Lmax = Z x S S in mm2, Z in Ohm, Lmax in meters The table below indicates these values, for 3 common sizes. Load Impedance () 2 Cable section Maximum Length (meters) 3 4 6 8 12 16 1,5 mm² (AWG #14) 3 4.5 2,5 mm² (AWG #12) 5 7.5 6 9 12 18 24 10 15 20 30 4 mm² (AWG #10) 8 12 40 16 24 32 48 64 IMPORTANT Long speaker cables induce capacitive effects – up to hundreds of pF depending on the quality of the cable - with a low-pass effect on high frequencies. If long speaker cables must be used, ensure that they do not remain coiled while in use. Page 12/82 3 AMPLIFIER SELECTION FOR USE WITH PS-SERIES AMPLIFIER SELECTION FOR USE WITH PS-SERIES NEXO recommends high power amplifiers in all cases. Budget constraints are the only reason to select lower power amplifiers. A lower power amplifier will not reduce the chances of driver damage due to over-excursion, and may actually increase the risk of thermal damage due to sustained clipping. If an incident occurs on an installation without protection, the fact that amplifiers only generating half their rated output power (-3dB) are used will not change anything in respect of possible damage. This is due to the fact that the RMS power handling of the weakest component in the system is always 6 to 10 dB lower than the amplifier rating. 3.1 PS and LS recommended amplification Nexo recommends amplifiers in agreement with table below: Recommended Amplifier# Channel 1 Channel 2 LF in Active Mode or HF in Active Mode LF+HF in Passive Mode LS400 PS8 3.1.1 300 to 700 W / 6 Ohms 200 to 500 W / 8 Ohms LS600 1000 to 2000 W / 8 Ohms PS10R2 500 to 1250 W / 8 Ohms PS15R2 Passive Mode 1000 to 2000 W / 8 Ohms PS15R2 Active Mode 1000 to 2000 W / 8 Ohms 250 to 500 W / 16 Ohms Current rating It is very important that the amplifier behaves correctly under low load conditions. A speaker system is reactive by nature: on transient signals like music it will require four to ten times more instantaneous current than its nominal impedance would indicate. Amplifiers are generally specified by continuous RMS power into resistive loads, however the only useful information about current capacity is the specification into a 2 Ohm load. It is possible to perform an amplifier listening test by loading the amps with twice the number of cabinets considered for the application (2 speakers per channel instead of one, 4 instead of 2) and running the amps up to the onset of clipping. If the signal does not noticeably deteriorate, the amplifier is well adapted (overheating after approximately ten minutes is normal but thermal protection must not operate too quickly after starting this test). 3.1.2 Amplifier settings Gain value Gain is the key to correct alignment of the system. It is especially important to know the gain of all amplifiers used in your set-up. The tolerance should be about ±0.5 dB. In practice this can be difficult to achieve because:  Some amplifier brands have an identical input sensitivity for models of different power rating (this infers a different voltage gain for each model). For example, a range of amplifiers with different power outputs, all having a published input sensitivity of 775mV/0dBm or 1.55V/+6dBm, will have a wide range of actual gains – the higher the power, the greater the gain.  Various other brands may offer constant gain but only within a given product range, for example they may fit fixed input sensitivity only on their semi-professional amps.  Even if a manufacturer applies the constant gain rule to all models, the value selected will not necessarily be the same as that chosen by other manufacturers. AMPLIFIER SELECTION FOR USE WITH PS-SERIES Page 13/82  Some products can exhibit manufacturing tolerances for the same model of ±1dB or more. Some amplifiers may have been modified, possibly without any label indicating the new values. Others may have gain switches fitted internally where it is impossible for the user to verify the actual setting without opening the amplifier casing.  In cases where you don't know the gain of your amplifier (or want to check it) please follow this procedure: 1) Unplug any loudspeakers from the amplifier outputs 2) With a signal generator, feed a sine wave at 1000Hz at a known voltage (say 0.5V) to the input of the amplifier under test 3) Measure the voltage at the output of the amplifier 4) Calculate the gain using the formula Gain = 20 * LOG10(Vout/Vin). Some examples: Vin / Gain 0.1 V 20dB 1V 26dB 2V 32dB 4V 37dB (1.4V sensitivity / 1350Wrms) 7.1 V 0.5 V 5V 10 V 20 V 35.4 V 1V 10 V 20 V 40 V 70.8 V Remember that constant sensitivity settings will give a different gain value when the amplifier power is different. NEXO recommends low gain amplifiers: +26dB is recommended, as it is at the same time adequately low and quite common amongst amplifier manufacturers. This gain setting improves signal to noise ratio and allows all preceding electronic equipment, including the NX242 TDcontroller or PS TDControllers, to operate at optimum level. Remember that using a high gain amplifier will raise the noise floor proportionally. Operating Mode Most two channel amplifiers available on the pro-audio market have the following operating modes:  Stereo: two fully independent channels deliver identical power into identical loads  NEXO recommends Stereo Mode for all amplifier channels feeding PS Series speakers.  Bridge-Mono: the second signal channel processes the same input as the first channel, but with reversed phase. The (single) load is connected between the two positive channel outputs using a suitable connection. While the total output of the amplifier remains the same, the available output voltage, the minimum impedance that can be connected and the voltage gain are doubled as compared with stereo operation. Typically, only channel 1 input is active. Positive and negative output connections vary depending on amplifier manufacturers.  NEXO does not recommend Bridge Mono Mode unless amplifier power is clearly not sufficient. Page 14/82 AMPLIFIER SELECTION FOR USE WITH PS-SERIES IMPORTANT When in Bridge-Mono mode, check your amplifier user manual for proper connection of outputs 1(+) and (2+) in relation to input phase.  Parallel-mono: the output terminals of the two channels are configured in parallel using an internal relay. The (single) load is connected either to the output of channel 1 or to that of channel 2 (as if in stereo). While the total output of the amplifier remains the same the output voltage level is also the same as in stereo mode. The minimum impedance that can be connected is reduced by half due to the fact that current capability is doubled. Typically, only channel 1 input is active.  NEXO does not recommend Parallel-Mono Mode for any PS Series speaker amplification. Warning on amplifiers signal processing features Some high-end amplifiers may include signal processing functions similar to those found in the NX242 TDcontroller or in PS TDControllers ("loudspeaker offset integration", "limiter", "compressor," etc.). Moreover, when this processing is digital, computation latency time can introduce a few milliseconds delay from input to output. These functions are not adapted to specific system requirements and may interfere with the complex protection algorithms used in the NEXO TD Controllers. NEXO do not advise using other protection systems in conjunction with the NEXO TD Controllers and they should be disabled. IMPORTANT For proper system protection, no latency time or non-linear devices should be introduced between the output of the NEXO TDcontroller and the input of loudspeakers through use of DSP modules such as internal amplifier signal processing. 3.2 PS Series systems and NXAMP TDControllers NEXO Powered TDControllers NXAMP 4X1 & 4X4 are integrated solutions for Control and amplification for all NEXO speaker ranges.

This concept was previously only available for highly specialized applications; in the general purpose PS it is fully exploited thanks to a practical design that makes user configuration of the horn practical and quick. The proper configurations of the horn for two common applications are shown below. All 4 positions of the horn are possible and can be useful for specialized applications such as complex arrays, systems designed with CAD software and stage monitoring. The specific dispersion of the PS8, PS10 & PS15 horn can be seen on figure 1 ("front of house" configuration): 6.2  As seen on the side view, vertical coverage is narrower above horn axis (+25°) than below (-30°).  As seen on the front view, horizontal coverage is narrower above horn axis (50° Horizontal for +25° Vertical) and wider below (100° Horizontal for -30° Vertical). Between these two extremes horizontal coverage varies according to a specific law; on axis (0° Vertical) coverage is 75° Horizontal. Change of configuration Access to the horn for configuration and checking is easily made by removing the front grille (4 TORX screws to be removed top and bottom of the cabinets, see figure below). To modify horn orientation, remove the four Allen 4 metric or TORX TX25 screws that hold the horn in place. A sticker on the wide dispersion side of the horn shows the correct orientation for wedge monitoring and front of house applications: you simply position the indication on the desired side. The arrow indicates the wide dispersion. Page 28/82 6.3 CONFIGURABLE ASYMETRICAL HORN « Front of house » Configuration (default configuration) Good coverage of audiences often requires a conflicting combination of wide coverage ("short-throw") for the closest listeners (below cabinet axis) and narrow coverage ("long-throw") for distant areas (on or above axis). The PS Series horizontal horn coverage varies from "short-throw" to "long-throw" along the vertical axis to precisely match these practical requirements in a single system. For the majority of applications, the asymmetrical horn should be used with its "wide" dispersion side directed towards the floor (as shown by the arrow) but all four cabinet orientations are usable. 6.4 « Stage Monitor » Configuration For stage monitors the required coverage is always wider when performers are close to the wedge (above the horn axis) than when they move away from it (below the horn axis). For floor monitor use the horn must be rotated with its "wide" dispersion side directed towards the top of the cabinet (as shown by the arrow) in wedge position as shown in the above figure. The specific dispersion pattern, the 2" driver and the very high power handling all contribute to the exceptional performance of the PS15 as a wedge monitor. PS SERIES HARDWARE SETUP PROCEDURE 7 Page 29/82 PS SERIES HARDWARE SETUP PROCEDURE Before proceeding with installation of PS series, please ensure that the components are present and undamaged. A component list is appended to this manual. In the event of any shortage, please contact your supplier. 7.1 SAFETY FIRST PS Series accessories structural computations and related documents are available at Nexo ([email protected]) upon request. We include this section to remind you of safe practice when flying the PS Series. Please read it carefully. However, user must always apply his or her knowledge, experience and common sense. If in any doubt, seek advice from your supplier or NEXO agent. The PS Series accessory range is a professional precision tool set, and should be handled with extreme care. Only persons. Misuse of these accessories could lead to dangerous consequences. Used and maintained correctly, PS Series accessories will give many years of reliable service in portable systems. Please take the time to read and understand this manual. Flown Systems Safety  Always inspect all the rigging components and cabinets for damage before assembly. Pay special attention to the lifting points, and safety clips. If you suspect that any of the components are damaged or defective, DO NOT USE THE AFFECTED PARTS. Contact your supplier for replacements.  Read this manual carefully. Also be familiar with the manuals and safe working procedures for any ancillary equipment that will be used with PS Series accessories.  Ensure that all local and National regulations regarding the safety and operation of flying equipment are understood and adhered to. Information on these regulations can usually be obtained from Local Government Offices.  When deploying a PS Series system always wear protective headwear, footwear and eye protection.  Do not allow inexperienced persons to handle a PS Series system. Installation personnel should be trained in loudspeaker flying techniques and should be fully conversant with this manual.  Ensure that motor hoists, hoist control systems and ancillary rigging components are currently certified as safe and that they pass a visual inspection prior to use.  Ensure that public and personnel are not allowed to pass beneath the system during the installation process. The work area should be isolated from public access.  Never leave the system unattended during the installation process.  Do not place any object, no matter how small or light, on top of the system during the installation procedure. The object may fall when the system is flown and is likely to cause injury.  Secondary safety steels must be installed once the system has been flown to the operating height. Secondary steels must be fitted irrespective of requirements of the local safety standards applicable to the territory.  Ensure that the system is secure and prevented from pivoting around the motor hoist.  Avoid any form of excessive dynamic loading to the assembly (structural computations on PS Series Rigging System are based on a 1/1.2 factor for hoist or motor acceleration).  NEVER attach any item to the PS Series system other than the PS Series accessories.  When flying outdoor systems ensure that the system is not exposed to excessive wind or snow loads and is protected from rainfall. Page 30/82 7.1.1 PS SERIES HARDWARE SETUP PROCEDURE  The PS Series Rigging System requires regular inspection and testing by a competent test centre. NEXO recommend that the system is load tested and certified annually or more frequently if local regulations require.  When de-rigging the system ensure that the same duty of care is given to the procedure as for the installation. Pack PS Series components carefully to prevent damage in transit. Ground Stacking Safety Statistically, many more injuries occur due to unstable ground stacked PA systems than those associated with flown systems. There are several reasons for this fact, however the message is clear: 7.1.2  Always survey the supporting structure upon which a ground stack is to be built. Always look beneath PA wings to inspect the deck support and if necessary ask for the stage scrims and dressings be removed to allow access.  If the stage surface slopes, as it does in some theatres, ensure that the system is prevented from sliding forwards due to vibration. This may require the fitting of timber battens to the stage floor.  For outdoor systems ensure that that the system is protected from wind forces which might cause the ground stack to become unstable. Wind forces can be huge, especially upon large systems, and should never be underestimated. Observe meteorological forecasts, calculate the “worst case” effect upon the system prior to erection and ensure that the system is secured appropriately.  Take care when stacking cabinets. Always employ safe lifting procedures and never attempt to build stacks without sufficient personnel and equipment.  Never allow anyone, whether operators, artists or members of the public to climb onto a ground stacked PA system. Anyone who needs to climb over 2m (6 ft) high should be fitted with suitable safely equipment including a clip-on harness. Please refer to local Health and Safety legislation in your territory. Your dealer can help with advice on access to this information.  Apply the same attention to all safety matters when de-stacking systems.  Be aware that safety procedures are as important in the truck and in the warehouse as they are at the venue.

NEXO recommends regular testing of loudspeaker rigging components, preferably using a suitable test rig coupled with a visual inspection.  Fasteners: there are several critical points in the PS cabinets.  Of primary concern are: a) The grid screws attaching the grid to the cabinet b) The machine screws attaching the connecting plates to the cabinet. c) The screws attaching the directivity flanges to the front of the cabinet.  These fasteners should be regularly checked and tightened as necessary.  Cleaning: The exterior of the cabinet and the rigging system can be cleaned with a damp cloth soaked in mild soapy water. On no account use solvent based cleaners , which may damage the finish of the cabinet  After cleaning, the PS accessories must be treated with a suitable lubricant to prevent rusting. NEXO recommends the use of Scottoil FS365 which is a water-based lubricant with a mixture of machine oil, surfactant and anti-rust treatment.

NEXO ANALOGUE PSTD CONTROLLERS Page 47/82 WARNING ! THIS APPLIANCE CLASS 1 APPARATUS AND MUST BE EATHED. The green and yellow wire of the mains cord must always be connected to an installation safety earth or ground. The earth is essential for personal safety as well as the correct operation of the system, and is internally connected to all exposed metal surfaces. Additional recommendation for interconnection to other equipment can be found in the “Analogue TDcontroller Setting-Up Advice” section. 8.3 Analogue TDcontroller Setting-Up Advice 8.3.1 Mains Power NEXO TDcontrollers don’t provide a mean to switch off the unit from the front panel. As they are intended to be rack mounted the back panel is not accessible during use. Therefore it is left to the user to provide a disconnection mean readily operable. 8.3.2 Voltage setting NEXO TDcontrollers use a switch mode power supply (SMPS). This SMPS accepts universal AC power input voltages in the range 90V to 264V, and requires no manual adjustment for voltages in this range. 8.3.3 Mounting the TDcontroller in a rack (Grounding, shielding & safety issues) The TDcontroller is intended for rack mounting. The only accessible part during use shall be the front panel of the TDcontroller. Any space above or under the TDcontroller shall be obstructed with a blank panel. The rack is a free grounding and shielding structure and it provides extra shielding. Therefore, it is desirable that the screws used to fix the TDcontroller in the frame or rack provide an electrical contact between the chassis of the TDcontroller and the rack. The primary reason for grounding is safety. Conformance to the applicable requirements of the authorities having jurisdiction is, of course, mandatory. However, grounding also has an impact on electromagnetic compatibility. From the EMC point of view, it is desirable to have a low impedance ground network, as a current flowing in the ground network will then produce low voltage in the network. A low impedance network can be obtained using a multipoint ground scheme, with as many closed ground loops as is economically possible. 8.3.4 Fuse The fuse provided in the unit will not blow during normal operation. If the fuse blows the TDcontroller has malfunctioned. This fuse must only be changed by NEXO certified service personnel. In any case do not replace the fuse with a non-certified NEXO fuse, as this will invalidate the NEXO warranty. Page 48/82 NEXO ANALOGUE PSTD CONTROLLERS CAUTION! This servicing instruction is for use by qualified service personnel only. To reduce the risk of electric shock, do not perform any servicing other than that contained in the operating instructions unless you are qualified to do so. 8.3.5 Recommendations for wiring the sense lines The impedance of the sense inputs of the TDcontroller are high, so currents are low and therefore light duty cable can be used. If the TDcontroller is housed in the amplifier racks an unshielded cable may be used. If the TDcontroller is located remotely - at the mixing position - a shielded cable is recommended, without using the shield as a conductor. The cable must be well protected from public access, as it carries potentially dangerous amplifier voltage. When one of the channels is not being used and the corresponding sense line is disconnected, cross talk onto the inactive sense line may in some cases produce signals capable of causing the inadvertent illumination of the Sense LED on that channel; although this has no effect on the internal operation of the TDcontroller, it can be cured by short-circuiting the terminals of the inactive sense line. 8.3.6 Recommendations for wiring the audio outputs The output stages can drive several amplifiers in parallel; however it is not advisable to work with loads of less than 1kOhm(and strictly forbidden to drive less than 600Ohms). It is best to check the impedance characteristics of the amplifier inputs - supplied by the manufacturer - to check how many amplifier channels can be paralleled. Where precise information is not available (and taking 10kOhm as the minimum value possible), ten channels in parallel per output is a sensible maximum. 8.3.7 Electromagnetic environments The emission (this word describes all types of electromagnetic noise radiated by the equipment) requirements which have been applied to Nexo’s TDcontrollers are the stringent requirements of the ”Commercial and light industrial environment” of the product family EMC standard for emission. The immunity (this word describes the ability to cope with electromagnetic disturbance generated by other items and natural phenomena) requirements that we have considered exceed those applicable to the ”Commercial and light industrial environment” of the product family EMC standard for immunity. In order to provide a further safety margin, we recommend that you do not operate the TDcontrollers in the presence of electromagnetic interference exceeding half of the limits found in this standard. These two EMC standards are those applicable to pro-audio equipment for the implementation of the ”EMC directive”. 8.3.8 Analogue signal cables Analogue signals should be connected to the input and output ports of the TDcontroller via shielded twisted pair or starquad cable fitted with XLR connectors on the TDcontroller side. We recommend the use of low transfer impedance cables with a braided shield and a transfer impedance below 10 mΩ/m. For the sense inputs, the noise requirements are not as stringent, and any kind of twisted pair cable will be adequate. Title: symetrical_wiring.eps Creator: Adobe Illustrator(R) X Preview: This EPS picture was not saved with a preview included in it. Comment: This EPS picture will print to a PostScript printer, but not to other types of printers. The TDcontroller is intended to be used with symmetrical (balanced) sources (for instance a mixer) and symmetrical loads (for instance a power amplifier (see figure). You can see that the TDcontroller provides a low impedance path between pin 1 of its XLR connectors and its chassis. The TDcontroller can sustain high current in pin 1 without degradation of output noise. We recommend that the sources and loads you use have the same desirable characteristics. NEXO ANALOGUE PSTD CONTROLLERS Page 49/82 It is sometimes claimed that connecting cable shield at both ends creates ground loop, and that the current flowing in such loop will produce noise. This is not the case for most professional audio equipment. In short, there are two kinds of loop in which voltages are present: the loop formed by signal wires, and the loops formed by grounded conductors, among which are protective earth conductors (PE) and signal cable shields. When a cable shield is grounded at both ends, a loop is closed, and the resulting current causes a reduction of the voltage induced on signal lines. This effect is what the cable shield is intended to produce, since this is how it protects your signal from magnetic fields. If you are using an asymmetrical (unbalanced) source, it is recommended to use a shielded twisted pair and to connect wire 3 of the cable to the Title: Asymetrical_wiring.eps shield at the source output end (see figure). Creator: Illustrator(R) X This technique prevents noise currents Adobe Preview: This EPS picture was not saved flowing on the return path of the signal. If with a preview included in it. you are using an amplifier with an Comment: This EPS picture will print to a asymmetrical (unbalanced) input, it is best to PostScript printer, but not to use a shielded twisted pair, and to connect other types of printers. wire 3 at the TDcontroller end only, as shown in Fig. 2. This keep a good capacitance balance for the signal, however noise currents flow on the return path of the signal. (Note that this is only acceptable for a short cable). If you are using a symmetrical (balanced) source or amplifier which is prone to become noisy when a current of less than 100 mA at the mains frequency (50 Hz or 60 Hz) is sourced into pin 1 of its XLR connectors, you might consider opening the ground loop. 8.4 Analogue TDcontroller USER GUIDE Page 50/82 8.4.1 NEXO ANALOGUE PSTD CONTROLLERS Read before use The Analogue TDcontroller is designed to be used with its proper set of speaker cabinet. They are not interchangeable. Its main functions are:  To optimize the response of the system  When operating with the SubBass system (optional), splitting the stereo (2 channel) signal into 2 frequency bands (PS and dedicated SubBass system)  Active protection of the cabinets by dynamic audio signal processing (Temperature and Displacement servo control)  Reduction of amplifier overload (Peak limiter function) Analogue TDcontrollers also feature:  Stereo operation (2 independent channels) for the main system  Global switchable output level  Adjustable level on the SubBass channel  High CMRR input stage and High current drive output  Compensation of power compression effects on the system response curve. The Analogue TDcontroller is designed to be inserted between the Audio source (console, preamplifier, etc.) and the power amplifier. 8.4.2 Front Panel Most front panel functions and indicators are located inside 2 distinct windows: left-hand areas relate to functions and indicators dedicated to the optional Sub-bass section, while right-hand window contains indicators concerning servo control operation for the PS cabinets. For more technical details about servo control operation and internal electronic processing, please refer to section “TDcontroller REFERENCE GUIDE.” Page 53. Turning the LS channel Overlap / Crossover Pushing the CONFIGURE button modifies the high pass filtering. It does not affect the sub output, which will always be a filtered sub signal. (This is therefore not a Sub on/off button). In the « Overlap » position, PS is exploited to its maximum capability. This position should be used if the system is being used without a Subbass. It can also be used with the Subbass; In this case, there will be a boost in the crossover area. The « Cross over » position is generally recommended when using the Subbass. NEXO ANALOGUE PSTD CONTROLLERS Page 51/82 Adjusting the Subbass level (Sub Level) The potentiometer adjusts the level of the Subbass channel, a range of 12 dB allows a variety of configurations and application conditions to be accommodated. Center position of the knob is calibrated for 1 Subbass used with 2 distant PS. Amplifier & Protection indicator The bicolor green/red AMP LED indicates signal presence at the sense input of the concerned channel, allowing visual confirmation of the return connection of the Sense cables from the amplifier output. The LED is flashing red, when the Peak limiter is acting, reducing excessive peak voltage or levels capable of overloading the channel amplifier.  The yellow VLF LED indicates that displacement protection for the Subbass are engaged on the SubBass channel. The temperature protection is not monitored.  On each side of the PS main system window, yellow TEMP and DISP LEDs indicate when protection has been activated (temperature or displacement control) for the LF (the HF drivers temperature protection is not monitored). Peak Limiter adjustments The Analogue TDcontroller features two independent peak limiter trims (one for the SubBass amplifier section, one for the PS amplifier section), which allows the peak limiter to be set to limit the maximum power of the amp (without affecting the protections threshold). The peak limiter has no real cabinet protection functions; it must be tuned to avoid overdriving the amp that in turn can generate obvious clipping noise. To set the peak limiter to the correct value, either turn the trimmer clockwise until the red LED lights at the same time as the amp’s clipping LED, or use the graduation (power value given for 8load). 8.4.3 Rear Panel Audio Inputs The audio inputs are two 3-pin female XLR connectors located in the area labeled BALANCED INPUTS. Signal is applied between pins 2 and 3, pin 1 is connected to ground. When the Controller is linked to a signal source with balanced outputs, the XLR connections are simply wired pin to pin (1 to 1, etc.). As a result of the balanced nature of the outputs (and providing that balancing is respected by way of the connection to the amplifier), there is no hot or cold pin - the Analogue TDcontroller being neutral regarding the polarity of the signal. Page 52/82 NEXO ANALOGUE PSTD CONTROLLERS Output Level Switch The 3-position output level switch is used to match the processor gain to the amplifier gain for optimum signal to noise ratio. The three gain values available are +6, 0 or -6 dB. For minimum noise floor the 6dB setting should be chosen, for maximum headroom the +6dB position should be used. Audio Outputs The audio outputs are the three 3-pin male XLRs located in the area labeled BALANCED OUTPUTS. The channel corresponding to each output connector is identified by the labels Left, Right and Sub L+R (mono SubBass). Signal is applied between pins 2 and 3, pin 1 is connected to ground. When used with an amplifier with balanced inputs, the wiring of the output XLR is simply pin to pin (1 to 1, etc.), the polarity of the signal being preserved if the source connected to the input is also balanced (see previous section). Sense inputs The sense inputs of the three channels (left, right and SUB) are arranged on a sixpole barrier strip set into the rear panel within the area labeled SENSE INPUT. The Sense inputs are intended for connection to the output signals of the amplifiers driving one cabinet of each the channels being used. Connection is made via the female part - removable - of the connector (supplied with the Controller) as outlined below: Channel PS Left PS Right LS600 or RS15 Amplifier Output Terminal - (black) + (red) - (black) + (red) - (black) + (red)       Barrier strip connector pin 1 (figure) pin 2 pin 3 pin 4 pin 5 pin 6 Input sense connection MANDATORY for proper operation of the servo-control system, the cabinets will NOT BE PROTECTED if the sense lines are unconnected. Earth Lift The push button labeled « Earth Lift » allows connection (depressed position), or disconnection (out position) between the signal ground and the mains earth, which is itself linked to the chassis. Using this button may help to eliminate hum due to ground loops created in the system. Sub jumper In certain applications you may wish to disable the mono summation (but keep the 6dB gain boost) on the sub channel. By moving the internal jumper ST1 inside the unit, the sub channel will only use the Right input (with 6dB gain to keep the same sub level when the mono summation is enabled). Always ensure that your TDcontroller is disconnected from main before opening the unit. Remove the 3 screws fastening the top panel. The ST1 jumper is located near the Input XLR. The PIN1 being the PIN closest of the Input XLR. Strap PIN 1-2 (B in the drawing) in order to drive the sub only from input R. Strapping Pin 2-3 (labeled A, factory default) will provide the summation of channel R&L. NEXO ANALOGUE PSTD CONTROLLERS 8.5 Page 53/82 TDcontroller REFERENCE GUIDE 8.5.1 Linear section The characteristics of the linear section are independent of signal level, as opposed to the servo control functions described in next paragraph. Subsonic and VHF filtering Low and high-pass filters are used to remove signals out of the usable frequency range, eliminating sub- and ultra-sonic components that could possibly degrade the performance of the Controller and amplifiers. These filters are optimized to realize the overall target system response. Equalizing acoustical response This equalization section provides the required correction to obtain a flat system response, as the cabinets are acoustically designed for maximum efficiency in the whole frequency range. Active rather than passive attenuation allows amplifier voltages to be lowering for a given output SPL and therefore increases the maximum SPL achievable with the same amplifier. Active equalization also extends system bandpass, especially at low frequencies where acoustical performance is limited by cabinet size. PS / Subbass Cross-Over From input signals summed together, the resulting mono signal is low-pass filtered to feed the SubBass channel. When the channel is turned on (Subbass On), main channels (Left & Right) high-pass filters are reconfigured to filter out signal components below the crossover frequency. Slopes and other filter characteristics are optimized using techniques optimized for the actual acoustical data of each driver. 8.5.2 Servo Control section Servo control of the PS TDcontroller is intended to work with amplifier return signals present at the Sense inputs (monitored by front panel LEDs). VCAs and VCEQs Each of the 3 Audio channels (Left, Right and SubBass) contains two voltage controlled elements driven by servo signals:  One operates on the whole frequency range (wide band VCA).  The other elements work selectively as dynamic equalizers (LF-VCEQ & HF-VCEQ). Depending on the nature and origin of the servo signals, either one or the 3 combined elements is used to process the Audio signal. This feature allows more efficient processing while reducing audible effects. Page 54/82 NEXO ANALOGUE PSTD CONTROLLERS Displacement control The signal from the sense input is fed through a shaping filter producing a signal proportional to the voice coil displacement. This control signal is compared to a fixed value and if exceeded, the LF-VCEQ is activated with very short attack time to reduce speaker excursion. Temperature control Sense input is fed to a shaping filter to create a voltage proportional to the instantaneous voice-coil current. The signal is integrated over time to simulate heat buildup in the specific driver. When the resulting voltage exceeds a preset threshold, the VCA is activated to limit the voice coil temperature within its safety range. Power compression is also simulated by lowering the high frequencies when temperature protection is acting on the bass loudspeaker. Dynamic control To reduce audible « pumping » effects due to very long time constants of temperature detection signals, an alternate integration is also processed with a shorter time constant. Whilst anticipating the temperature protection and reducing its unwanted effects, action of this signal also improves dynamics control. Peak Limiter The above mentioned devices provide reliable protection against potential speaker over-heating and over-excursion. Nevertheless driving the cabinets at very high peak voltages (with oversized amplifiers) as well as delivering distorted signals might be dangerous for the speakers. The Peak limiter is both useful for:  Maintaining good sound quality at high levels (it will reduce amplifier distortion).  Increasing protection reliability (limiting peak voltages to levels that speakers can permanently withstand, and reducing the occurrence of subsonic signals delivered by overloaded amplifiers) TECHNICAL SPECIFICATIONS 9 Page 55/82 TECHNICAL SPECIFICATIONS 9.1 PS8 – LS400 9.1.1 System specifications SYSTEM SPECIFICATIONS PS8 with PS8 TDcontroller LSub 400 with PS8 TDcontroller Frequency Response [a] 69 Hz - 19 kHz ±3dB 43 Hz - 120 Hz ±3dB Usable Range @-6dB [a] 62 Hz – 20 kHz 40 Hz - 140 Hz Sensitivity 1W @ 1m [b] 96 dB SPL Nominal - 94 dB SPL Wideband 99 dB SPL Nominal Nominal Peak SPL @ 1m [b] 122 to 125dB Peak 128 to 131 dB Peak HF Dispersion [c] 50° to 100° Hor. x 55° Vert.
