Crest Audio PCX 88 DSP Matrix & Loudspeaker Management Processor

Professional‑grade DSP matrix processor — precise audio routing, speaker management and multi‑zone control for live sound, venues, or installed systems.

The Crest Audio PCX 88 is a DSP‑based digital audio matrix and loudspeaker management system engineered for professional audio installations, venues, clubs, houses of worship, conference halls or touring rigs. Boasting a 96 kHz sample rate and 32‑bit floating‑point SHARC DSP with 24‑bit delta‑sigma A/D and D/A conversion, it delivers clean, high‑fidelity audio with minimal coloration and reliable performance across inputs and outputs. With 8 balanced XLR inputs and 8 balanced XLR outputs — expandable via optional Dante® digital network card for additional 8‑in / 8‑out digital channels over Ethernet — PCX 88 offers flexible routing, crossover and signal processing to manage front‑of‑house, monitors or multi‑zone speaker arrays with ease. 

Key Features

• 16‑channel DSP matrix (8 analog in / 8 analog out + optional 8 digital in / 8 digital out via Dante): Route any input to any output — ideal for complex, multi‑zone or multi‑speaker setups. 
• High‑quality DSP engine: 96 kHz sample rate, 32‑bit SHARC DSP, 24‑bit Delta‑Sigma A/D and D/A converters for transparent, low‑noise audio processing. 
• Comprehensive input processing per channel: Gain, mute, high‑pass/low‑pass filters, 5‑band parametric EQ, polarity/phase, noise‑gate, feedback control, automix (for multiple mics) and +48 V phantom power on analog inputs. 
• Advanced output processing per channel: HP/LP filters, 5‑band EQ, gain, compressor/limiter, polarity/phase, delay (up to 680 ms), mute — ideal for crossover, subwoofer management or individual zone tuning. 
• Flexible crossover/band‑pass filters: Choose between Butterworth, Bessel or Linkwitz‑Riley alignments; orders from 1st (6 dB/oct) up to 4th (24 dB/oct) — useful for speaker tuning and system protection.
• Built‑in signal generator: Sine, pink noise and white noise — useful for system calibration, room tuning or testing.
• Remote configuration & control: Front‑panel USB Type‑B port or rear-panel Ethernet (or legacy serial) — manage multiple units (up to 255) from a PC for large installations.
• Wide dynamic range and high headroom: Input-to-output dynamic range > 110 dB (A‑weighted), max input/output level +20 dBu on balanced XLR — for clean, professional signal quality.
• Rack‑mountable chassis: Standard 19" form factor — suitable for touring racks, installation racks or permanent studio setups.

Technical Specifications

Best For

• Multi‑zone installations — venues, auditoriums, hotels, corporate buildings, schools — needing flexible audio routing and zone-based control.
• Live sound FOH or monitor rigs — for mixing, processing and routing multiple inputs to multiple speaker outputs with precise DSP control.
• Houses of worship, conference halls, theatres — where speaker management, crossover control, and multi‑input/output handling is essential for clarity and reliability.
• Portable PA setups and touring systems — rack‑mountable, Dante‑ready, and suitable for complex speaker arrangements or mixed analog/digital sources.
• Audio integrators and installers who need a powerful, flexible “brain” for loudspeaker management, crossover control, signal processing, and routing in one device.
