The PS15 TD MkII provides crossover, sensed amplifier control and system equalisation optimised for the PS15, PS15Bass and LS1200. One PS15 TD MkII has two inputs and three outputs, including summed sub out, minimising installation cost and complexity. Like all NEXO processors, the PS15 TD MkII provides precision dynamic, voice coil temperature and diaphragm displacement protection through the use of selective Voltage Controlled Equalisers (VCEQs), reducing levels only at frequencies when and where necessary.
