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.
