introduction 1 welcome Congratulations on your purchase of a new CPX Series power amplifier, and thank you for your confidence in Crest Audio products. You are among the growing number of audio professionals who have made Crest Audio one of the world’s leading suppliers of professional and commercial/industrial audio systems. For your safety, please read the Important Precautions section before installing and operating the amplifier. The Crest Audio CPX Series amplifiers are designed for high operating efficiency and accurate sonic performance across the full audio bandwidth, even under stressful conditions. CPX series amplifiers feature a 2-way crossover and sub-sonic (low-cut) filter for each channel. Crossover frequencies are fixed at 150 Hz, allowing subwoofers to be driven at extremely high sound pressure levels, and the filters cut at 40 Hz to prevent low-end rumble. Using proven technology gained through years of amplifier design, this unit takes advantage of rugged TO-3P output devices mounted on massive aluminum extrusions and dissipates heat via an extremely quiet and effective 2-speed fan. CPX amplifiers employ mammoth toroidal power transformers and offer impressive specifications and features not found on similarly priced competitive units. These amps are designed to drive a 2-ohm load per channel, thus achieving awesome performance levels into 4 ohms in BRIDGE mode. CPX amplifiers are ruggedly constructed, rack-mountable pieces of gear with superb patching capability, allowing superior flexibility in application. Front panel features include calibrated, detented gain (dB) controls and LED indicators for power (PWR), signal presence (SIG), and GCL (Gain Comparator Limiter) activation on each channel, as well as a rocker mains POWER switch. The back panel contains an IEC connector for the mains power cord, a mains circuit breaker with reset, and the critical cooling fan opening. This opening should have an adequate supply of cool air and should never be blocked or restricted. Also on the back panel are the input and output sections, including an input barrier strip for permanent installations. Each channel input section includes a combo XLR / ¼" phone jack connector, THRU/LOW out and HIGH out ¼" jacks, and activation switches for the LOW CUT filter and crossover (150 Hz XOVER). Channel output sections feature dual shock-proof binding posts and 4-conductor Speakon connectors. An additional 4-conductor Speakon connector allows BRIDGE mode output. p. 3
