The Crest Audio PCX 88-230EB is the most advanced processor in the PCX Series, designed for large-scale, high-performance audio systems that require full matrix routing, advanced DSP processing, and network-ready flexibility. It combines loudspeaker management, matrix mixing, and system control into a single powerful unit—making it ideal for complex installations and professional live sound environments.
At its core, the PCX 88 features an 8-input / 8-output analog matrix architecture, with the ability to expand to 16×16 channels via optional Dante network audio. This allows seamless integration into modern digital audio networks while maintaining full flexibility in routing and system design.
Operating at a 96 kHz sample rate with 24-bit converters and 32-bit DSP processing, the unit delivers extremely accurate signal processing, low noise, and high dynamic range—ensuring pristine audio quality across complex systems.
Each input channel includes gain, mute, high/low-pass filters, 5-band parametric EQ, noise gate, feedback suppression, automixing, and +48V phantom power, making it suitable for both line-level and microphone-level signals.
On the output side, the processor offers 5-band PEQ, compressor/limiter, crossover filters, polarity control, and up to 680 ms delay, enabling full optimization and protection of loudspeaker systems.
With Ethernet, USB, and serial control, plus PCX Editor software support, the PCX 88 allows remote configuration and control of up to 255 devices, making it ideal for large distributed systems such as hotels, malls, and venues.
