Description
Crest Audio PCX 88 DSP Matrix & Loudspeaker Management Processor
Professionalgrade DSP matrix processor precise audio routing, speaker management and multizone control for live sound, venues, or installed systems.
The Crest Audio PCX 88 is a DSPbased digital audio matrix and loudspeaker management system engineered for professional audio installations, venues, clubs, houses of worship, conference halls or touring rigs. Boasting a 96kHz sample rate and 32bit floatingpoint SHARC DSP with 24bit deltasigma A/D and D/A conversion, it delivers clean, highfidelity 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 8in / 8out digital channels over Ethernet PCX88 offers flexible routing, crossover and signal processing to manage frontofhouse, monitors or multizone speaker arrays with ease.
Key Features
- 16channel 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, multizone or multispeaker setups.
- Highquality DSP engine: 96kHz sample rate, 32bit SHARC DSP, 24bit DeltaSigma A/D and D/A converters for transparent, lownoise audio processing.
- Comprehensive input processing per channel: Gain, mute, highpass/lowpass filters, 5band parametric EQ, polarity/phase, noisegate, feedback control, automix (for multiple mics) and +48V phantom power on analog inputs.
- Advanced output processing per channel: HP/LP filters, 5band EQ, gain, compressor/limiter, polarity/phase, delay (up to 680ms), mute ideal for crossover, subwoofer management or individual zone tuning.
- Flexible crossover/bandpass filters: Choose between Butterworth, Bessel or LinkwitzRiley alignments; orders from 1st (6dB/oct) up to 4th (24dB/oct) useful for speaker tuning and system protection.
- Builtin signal generator: Sine, pink noise and white noise useful for system calibration, room tuning or testing.
- Remote configuration & control: Frontpanel USB TypeB 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 >110dB (Aweighted), max input/output level +20dBu on balanced XLR for clean, professional signal quality.
- Rackmountable chassis: Standard 19″ form factor suitable for touring racks, installation racks or permanent studio setups.
