Peavey PCX 480 DSP-based Loudspeaker Management System – 4 In & 8 Out

Crest Audio PCX 480 digital speaker management processor

The Crest Audio PCX 480 digital speaker management processor is designed to provide precise control, routing, and optimization for complex professional audio systems. Featuring a four-input and eight-output matrix configuration, the unit allows flexible signal routing where any input can be assigned to any or all outputs. This capability makes it ideal for front-of-house, monitor systems, and multi-zone speaker management applications.

Operating at a 96 kHz sample rate, the PCX 480 ensures high-resolution audio processing with exceptional clarity and minimal signal degradation. Its advanced DSP engine incorporates professional-grade algorithms for equalization, crossover configuration, delay alignment, and dynamic processing. With high-quality 24-bit Delta-Sigma A/D and D/A converters, the processor maintains excellent signal integrity and a dynamic range exceeding 109 dB, ensuring accurate and transparent audio reproduction.

Each input channel includes gain control, mute, high-pass and low-pass filters, polarity adjustment, 8-band parametric EQ, and up to 680 ms delay. Output channels expand processing capabilities with 9-band parametric EQ, compressor/limiter, crossover filters, delay, and polarity control. Multiple filter types including Butterworth, Bessel, and Linkwitz-Riley offer precise crossover alignment with slopes up to 48 dB per octave.

The unit features a front panel LCD interface with a rotary encoder for quick configuration, while Ethernet and USB connectivity enable full remote control via PCX Editor software. With built-in signal generation and comprehensive processing tools, the Crest Audio PCX 480 digital speaker management processor provides reliable, flexible, and high-performance system control for demanding professional audio environments.
