Page 14/82 A MPLIFIER S ELECTION FOR USE WITH PS-S ERIESIMPORTANTWhen in Bridge-Mono mode, check your amplifier user manual for proper connection ofoutputs 1(+) and (2+) in relation to input phase.• Parallel-mono: the output terminals of the two channels are configured in parallel using aninternal relay. The (single) load is connected either to the output of channel 1 or to that of channel2 (as if in stereo). While the total output of the amplifier remains the same the output voltage levelis also the same as in stereo mode. The minimum impedance that can be connected is reducedby 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 featuresSome high-end amplifiers may include signal processing functions similar to those found in the NX242TDcontroller or in PS TDControllers ("loudspeaker offset integration", "limiter", "compressor," etc.).Moreover, when this processing is digital, computation latency time can introduce a few millisecondsdelay from input to output. These functions are not adapted to specific system requirements and mayinterfere 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 andthey should be disabled.IMPORTANTFor proper system protection, no latency time or non-linear devices should beintroduced between the output of the NEXO TDcontroller and the input of loudspeakersthrough use of DSP modules such as internal amplifier signal processing.3.2 PS Series systems and NXAMP TDControllersNEXO Powered TDControllers NXAMP 4X1 & 4X4 are integrated solutions for Control and amplificationfor all NEXO speaker ranges.NXAMP4x1 and NXAMP4x4 power capability is listed in the table below:Mode 4 Channels Bridge StereoNXAMP4x1 4 x 650 Watts / 8 Ohms4 x 900 Watts / 4 Ohms4 x 1300 Watts / 2 Ohms2 x 1800 Watts / 8 Ohms2 x 2600 Watts / 4 OhmsNXAMP4x4 4 x 1900 Watts / 8 Ohms4 x 3400 Watts / 4 Ohms4 x 4000 Watts / 2 Ohms2 x 6800 Watts / 8 Ohms2 x 8000 Watts / 4 Ohms3.2.1 NXAMP connectorsNXAMP4x1 and NXAMP4x4 rear panels feature:• 4 analog inputs / outputs (links) on XLR3 connectors;• 4 digital inputs / outputs on RJ45 connectors with optional card;• 4 speaker level outputs on NL4FC connectors.
