Nexo PS8 TDcontroller, The PS8 TDcontroller is an advanced analogue processor that allows the PS8 Loudspeaker and optional LS400 Subwoofer to achieve superior performance from an exceptionally small format. The PS8 TD provides crossover, sensed amplifier control and system equalization, optimised for the PS8 and LS400. Each PS8 TD has two inputs and three outputs, L, R and summed sub out, minimising installation cost and complexity.

Like all NEXO processors, the PS8 TD provides precision dynamic, voice coil temperature and diaphragm displacement protection through the use of selective Voltage Controlled Equalisers (VCEQs), strategically reducing levels only at frequencies when and where necessary.

Features

• Precision circuits specifically engineered for the PS8/LS400 systems permit increased SPL and operational reliability.
• Servo-controlled VCEQs provide precise dynamic control without spectral imbalance.
• Two inputs and three outputs enable a single PS8 TD to manage multiple PS8 and LS400 products.
• Comprehensive status indicators and controls.
