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‚Äëchannel DSP matrix (8 analog in / 8 analog out + optional 8 digital in / 8 digital out via Dante): Route any input to any output ‚Äî ideal for complex, multi‚Äëzone or multi‚Äëspeaker setups.¬†
• High‚Äëquality DSP engine: 96‚ÄØkHz sample rate, 32‚Äëbit SHARC DSP, 24‚Äëbit Delta‚ÄëSigma A/D and D/A converters for transparent, low‚Äënoise audio processing.¬†
• Comprehensive input processing per channel: Gain, mute, high‚Äëpass/low‚Äëpass filters, 5‚Äëband parametric EQ, polarity/phase, noise‚Äëgate, feedback control, automix (for multiple mics) and +48‚ÄØV phantom power on analog inputs.¬†
• Advanced output processing per channel: HP/LP filters, 5‚Äëband EQ, gain, compressor/limiter, polarity/phase, delay (up to 680‚ÄØms), mute ‚Äî ideal for crossover, subwoofer management or individual zone tuning.¬†
• Flexible crossover/band‚Äëpass filters: Choose between Butterworth, Bessel or Linkwitz‚ÄëRiley alignments; orders from 1st (6‚ÄØdB/oct) up to 4th (24‚ÄØdB/oct) ‚Äî useful for speaker tuning and system protection.
• Built‚Äëin signal generator: Sine, pink noise and white noise ‚Äî useful for system calibration, room tuning or testing.
• Remote configuration & control: Front‚Äëpanel USB Type‚ÄëB port or rear-panel Ethernet (or legacy serial) ‚Äî manage multiple units (up to 255) from a PC for large installations.
• Wide dynamic range and high headroom: Input-to-output dynamic range >‚ÄØ110‚ÄØdB (A‚Äëweighted), max input/output level +20‚ÄØdBu on balanced XLR ‚Äî for clean, professional signal quality.
• Rack‚Äëmountable chassis: Standard 19" form factor ‚Äî suitable for touring racks, installation racks or permanent studio setups.
