Crest Audio launches PCX series of digital audio matrix processors

Crest Audio, a Peavey Commercial Audio brand, has introduced the PCX series of digital matrix speaker management processors.

Each of the three units in the PCX Series offers processing technology with inputs/outputs that can be routed in multiple configurations. Harnessing power and flexibility to perform loudspeaker management functions as well as matrix mixing, room combining, and other audio processing functions, the PCX Series is suitable for installed and portable sound systems. 

The three PCX Series units are distinguished primarily by their input/output configurations. The PCX 260 offers 2 XLR inputs and 6 XLR outputs; the PCX 480 offers 4/8 XLR I/Os; and the PCX 88 offers 8/8. Notably, on the PCX 88, an additional 8 digital input channels and 8 digital output channels, all independently assigned, are available over Ethernet with the optional Dante network audio card. 

On each PCX Series processor, the crossover filters are fully adjustable and any input can be routed to any output via the digital matrix system, allowing for any speaker management cabinet configuration. 

Each PCX Series has a 96kHz sample rate processing with an AD/DA interface (24-bit Delta Sigma) and filter response. Crest Audio’s software and DSP algorithms offer signal processing and control features to manage, optimise, and protect the FoH (front of house); monitor and multi-zone the speaker systems; and ensure audio signal clarity and integrity without loss. 

The front panel of the PCX 260 offers local configuration and control via a front-panel LCD display, rotary encoder, and dedicated function buttons. Alternatively, an RJ-45 Ethernet port, located at the back panel, allows for a higher-resolution graphical user interface configuration. PCX Series processors can be controlled in real time on the front panel or with the intuitive PCX Editor Software via back-panel Ethernet or front-panel USB interface. Serial control is possible via RS 232 and RS 485. A security lock feature is included.

Each input and output features 5-segment LED meters. Input features on the PCX 260 and PCX 480 include gain, mute, HP/LP, 8-band PEQ (parametric equaliser), polarity and up to 680ms of delay. Each output features an additional 9-band PEQ, gain, compressor/limiter, polarity, delay, mute, and crossover/band-pass filters. EQ filter types include PEQ, Low-Shelf, Hi-Shelf, Low-Pass, High-Pass, All-Pass1 and All-Pass2. The PCX 88 offers the distinctions of 5-band PEQ and phase on both input/output, as well as +48V phantom power, noise gate, feedback, and an Automix channel on input. 

All three processors have an internal signal generator providing sine, white noise, and pink noise. 

To round out the PCX Series adaptability, the firmware of each processor can be field updated. Additionally, each processor provides the ability to save presets that are nameable with a descriptive text entry. Each unit has an integrated power supply accepting AC mains voltages of 95 to 240VAC, 50/60Hz.
