TOA DP-SP3 CU Digital Speaker Processor - 2 Inputs / 6 Outputs, DSP
The TOA DP-SP3 CU is a compact digital speaker system processor with 2 analog inputs and 6 independent outputs, providing advanced DSP functions including 31-band parametric EQ, high/low-pass filters, compressor/limiter, delay, and crossover per channel for precise tuning of speaker systems. It is designed to optimize multi-way speaker arrays, zoned paging, and distributed audio installations in schools, offices, retail, stadiums, houses of worship, and commercial facilities requiring high-fidelity sound shaping and protection.
The processor supports TOA speaker presets for quick setup, crossover configurations for bi-amp/tri-amp systems, and remote control via RS-232C or optional remote panels. It features a 1U rack-mount chassis, front-panel LCD and controls for on-site adjustment, and LED metering for input/output levels and clipping.
