Peavey PCX 88 DSP-based Audio Matrix & Loudspeaker Management System – 16 In & 16 Out

Crest Audio PCX 88 digital audio matrix processor

The Crest Audio PCX 88 digital audio matrix processor is a high-performance DSP-based system designed for advanced audio routing, processing, and control in professional sound environments. Featuring a powerful 16-input and 16-output matrix architecture, the unit enables complete signal routing flexibility, allowing any input to be assigned to any output for complex system configurations such as front-of-house, monitoring, and multi-zone installations.

Operating at a 96 kHz sample rate and powered by a 32-bit SHARC DSP processor, the PCX 88 delivers precise audio processing with exceptional clarity and minimal noise. The system supports eight balanced analog XLR inputs and outputs, along with optional expansion via a Dante network audio card, enabling additional digital audio channels over Ethernet for scalable system integration.

Each input channel includes comprehensive processing tools such as gain control, noise gate, automix functionality, high-pass and low-pass filters, 5-band parametric EQ, polarity adjustment, and phantom power support. Output channels extend these capabilities with compressor/limiter processing, crossover filters, delay up to 680 ms, and additional EQ control to ensure optimal speaker performance and system protection.

Advanced filter options including Butterworth, Bessel, and Linkwitz-Riley allow precise crossover alignment, while the built-in signal generator supports system calibration using sine, white noise, and pink noise signals. Remote configuration and control are enabled through Ethernet, USB, or serial connection using PCX Editor software, supporting management of multiple units simultaneously. The Crest Audio PCX 88 digital audio matrix processor offers powerful, flexible, and reliable control for modern professional audio systems.
