INTRODUCTION ___________________________________________________________________________________________________ INTRODUCTION Thank you for selecting NEXO PS Series equipment. This manual will provide you with useful and important information about your PS speaker system: • PS8 & optional LS400 sub bass • PS10 & optional LS500 sub bass •... - Page 5 ___________________________________________________________________________________________________ These controllers are not interchangeable. Each one is precisely matched to the corresponding cabinets. Excepted NX241 that covers the entire NEXO range. NOTE: Earlier PS15TDs (up to serial number 1518) were designed for PS15s without the Impedance Compensation Network (ICN) (serial number < 23853) and the LS1000 Sub.

Page 9: Sub Bass Use (Optional)
LOUDSPEAKERS ___________________________________________________________________________________________________ Sub bass Use (optional) General Recommendations The Sub bass section of the TDcontroller is monophonic (the Left and Right channels are summed at the input of the Controller). In a Stereo sub bass installation using 2 TDcontrollers, bear in mind that when only one Controller input is used, this will lower the gain of the Sub Output by -6 dB (as the nominal level is calculated for a 2 input use). -

Page 12: Use & Maintenance
Use & Maintenance Checking the PS10 & PS15 internal fuses The following paragraph concerns only the PS10 and PS15 cabinets, since the PS8 is fitted with a re- settable fuse that does not require maintenance. The function of these fuses is to protect the passive crossover against overheating if a speaker component is accidentally disconnected or fails open circuit. -

Page 15: Ps15Td Mk2: Compatibility With Former Ps15Td, Ls1000 & Ps15 Cabinets
LS1000s cannot withstand the amount of energy provided by the new electrical cross-over. LS1000 above serial number 560 are equipped with the new 18’’ NEXO driver and with these units it is possible to use the TDcontroller MK2. Keep in mind that the cross-over is not tuned for the LS1000 architecture and sound quality will be not be as good as with the LS1200. - Page 16 It does not affect the sub output, which will always be a filtered sub signal. (This is therefore not a Sub on/off button although the older PS15TD operates as the PS8/PS10 units described above). In the « Overlap » position, the PS15 is exploited to its maximum capability. This position should be used if the system is being used without a LS1200.
- Page 17 P.17 TDCONTROLLER USER GUIDE ___________________________________________________________________________________________________ PS15 Gain control (PS15TD only) Two 12 dB range trimmers are provided to set the gain of L&R (HF & LF in active mode) channels. This adjustment can be useful in active mode where it is sometimes necessary to correct the gain difference of amplifiers which have different power and constant sensitivity.

P.18 TDCONTROLLER USER GUIDE ___________________________________________________________________________________________________ Rear Panel Audio Inputs The audio inputs are two 3-pin female XLR connectors located in the area labeled Audio IN, L and R being the left and right channels respectively. When using the active mode on the PS15TD only the Left channel XLR connector is used. - Page 19 P.19 TDCONTROLLER USER GUIDE ___________________________________________________________________________________________________ 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).

NB : The PS TDcontroller is insensitive to the polarity of the wiring of the inputs, contrary to some other NEXO Controllers. It is highly recommended that the user read the all of the information provided below regarding the wiring of Sense lines (0.0.0 : Recommendations for wiring the Sense lines). - Page 21 P.21 TDCONTROLLER USER GUIDE ___________________________________________________________________________________________________ Fuse holder (PS15) When necessary, the fuse should be replaced by a fuse of the same rating • for 230V : T100mAL250V • for 115V : T200mAL250V Mains Socket (PS15) WARNING : This appliance must be earthed. The socket is compatible with mains supply flexible cords which comply with IEC Publication 227.

P.22 TDCONTROLLER USER GUIDE ___________________________________________________________________________________________________ If your are using this TDcontroller with a PS15 cabinet without an ICN, the ICN jumpers must be set to the « A » position (left side). If not, a boost of 3dB at 1400Hz will result, affecting the sound quality of your system. -

P.23 TDCONTROLLER REFERENCE GUIDE ___________________________________________________________________________________________________ TDcontroller REFERENCE GUIDE 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. - Page 24 P.24 TDCONTROLLER REFERENCE GUIDE ___________________________________________________________________________________________________ • One operates on the whole frequency range (wide band VCA). • The other element works selectively as a dynamic equalizer (LF-VCEQ). Depending on the nature and origin of the servo signals, either one or the 2 combined elements is used to process the Audio signal.

Page 28: Stand Alone Amplifiers
Stand alone Amplifiers Recommended Power NEXO recommends high power amplifiers in all cases, budget constraints being the only reason to select lower power amplifiers. If a problem occurs on an installation without protection, the use of a lower power amplifier generating half their rated output power (-3dB) will not prevent possible damage. This is due to... - Page 29 Gain value NEXO recommends low gain amplifiers: +26dB is recommended, as it is both adequately low and quite common. This gain level considerably improves signal to noise ratio and allows all preceding electronic gear, including the TDcontroller, to operate at an optimum level. Remember that using a higher gain amplifier will proportionally raise the noise floor level by the same amount.
