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, minimizing 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.

KEY 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.

Architectural and Engineering Specifications
The 1RU PS8 TDController shall configure from a combination of two inputs and three outputs with each output providing crossover, parametric EQ, mid-filter limiters, and delay functions for NEXO PS8 products. The device shall have electronically balanced analogue inputs and outputs. All crossover, protection parameters, and EQ are factory optimized and not user-accessible. The controller must model loudspeaker temperature and displacement in real time. Protection shall be frequency selective and not allow PS8 loudspeakers to exceed speaker-dependent thresholds. The controller shall have three inputs providing feedback from amplifier output to allow real-time, real voltage protection. Maximum input shall be 22dBu with CMRR 70dB@1kHz and THD+N of 0.05% (max) at+18dBm Output. A 3-position, rear panel gain control shall switch between 38/32/26dB amplificatory gain, and the Output Section shall respectively display +22/+16/+10dBm into a 600W load. LEDs shall indicate status for; Power ON (green), Amp Sense & Peak (green/Red), Temperature & Displacement (yellow) and LS400 (VLF) displacement protection (also yellow). The chassis shall be constructed of steel with a black paint finish. Input power shall be 110-220VAC, 50-60Hz with a rear panel earth-lift. The 1RU device shall weigh 2.9kg (6.6lbs), with exterior dimensions of 483mm (19in) W, 44mm (1.75in) H and 190mm (7.5in) D. The controller shall be the NEXO PS8 TDController.
