MERIDIAN, MS — Crest Audio®, a Peavey Commercial Audio® brand, carries on the tradition of great sound quality, flexibility, and robustness with the continuation of the CPX™ Series of professional power amplifiers. Geared toward the needs of the touring and installation markets, the CPX Series offers versatile solutions designed to serve as the backbone of a mobile sound system, studio, and many other install applications requiring dynamically powerful yet affordable amplifiers.
CPX 1
The CPX Series is available in four models, the CPX 1, CPX 2 class A-B, and CPX 3, CPX 4 Class-H, with power ranging from 480W to 1,600W per channel. The amplifiers are designed to operate at line voltages as low as 50% of nominal and can drive loudspeaker circuits as low as 2 ohms per channel or 4 ohms when set to bridge mode. An exclusive Crest Audio feature of the CPX Series is the GCL™ (gain comparator limiting) system with a rear panel defeat switch. The GCL monitors input/output gain, reduces the signal when distortion or excessive high current conditions occur, and protects the loudspeakers from dangerous transients and unexpected level changes.
CPX 2
Beyond the GCL innovation, the CPX Series offers comprehensive audio processing capabilities, including two channel independent crossovers and a subsonic filter. The crossover frequencies are fixed at 150 Hz (CPX 1/2/3) or 100 Hz (CPX 4), allowing loudspeaker subwoofers to be driven at extremely high sound pressure levels, while the filter cuts at 40 Hz to prevent low-end rumble. The crossovers have direct outputs via heavy-duty, industry-standard connectors with THRU/LOW out and HIGH out TRS jacks. Channel output sections feature dual shock-proof binding posts (CPX 1/2/3) and four-conductor twist-lock connectors. For inputs, the CPX Series features combination XLR/¼-inch connectors with an added barrier strip for permanent installations (CPX 1/2/3).
CPX 3
The CPX Series front panel offers calibrated gain (dB) controls and LED indicators for power (PWR), signal presence (SIG), thermal protection, and distortion detection activation on each channel. A front panel rocker switch controls the mains power. The rear panel contains an IEC power connector, line voltage selector switch, dual primary fuses, and a two-speed DC cooling fan opening. Rounding out the robust back-panel features, the CPX Series offers the mode selector switch for stereo and bridge-mono operation, a toroidal power transformer, and a line voltage selector switch for 115V or 220V to 240V AC operation.
CPX 4
Each CPX Series chassis is constructed of high-quality, powder-coated sheet metal mountable within a typical 19-inch, professional equipment distribution frame.
From back to front, the CPX Series of power amplifiers are designed to meet and surpass the needs of operators, serving as a robust, feature-rich, and cost-effective amplification solution.
