CPXTM owner’s manual

welcome

Congratulations on your purchase of the CPX 3800 Series,a power ampli- fier designed for years of reliable, flawless operation under rigorous use. This amplifier offers the sonic superiority and unsurpassed reliability for which Crest Performance is famous while remaining surprisingly compact. Advanced technology and extensive protection circuitry allow operation with greater efficiency into difficult loads and power conditions. The GCL (Gain Comparator Limiting)™ circuit ensures trouble-free operation into loads as low as 2 ohms. The Gain Comparator Limiting circuit protects drivers and ensures that sonic integrity is maintained even in extreme overload conditions. The CPX 3800’s high-efficiency design uses tunnel-

cooled heat sinks and variable-speed DC fans. This cooling topology maintains a lower overall operating temperature, resulting in longer output transistor life. For your safety, read the important precautions section, as well as input, output,and power connection sections.

Although the CPX Series amplifiers are quite simple to operate and are housed in ultra-strong steel chassis, improper use can be dangerous. This amplifier is very high powered and can put out high voltages and sizable currents at frequencies up to 30 kHz. Always use safe operating techniques when operating this amplifier.

For your safety, read the important precautions section, as well as input, output and power connection sections.
