CD Series power amps all include multiple protection circuits such as Active Clip Limiting, which automatically reduces gain at the onset of clipping; Instantaneous Gain Modulation, which monitors load current to protect against overloading; Autoramp, to prevent abrupt turn-on levels by gradually increasing gain; as well as short circuit, DC voltage, comprehensive thermal management, current in-rush turn on/off transient and sub/ultrasonic input.
Crest Audio also introduced the CM Series industrial power amplifiers, designed for multi-channel applications in nightclubs, restaurants, hotels, retail stores and video conferencing systems. The 4-channel CM 2204 and 8-channel CM 2208 claim low impedance or 70V operation at the same power levels without switching. Each amplifier in the chassis will operate to rated power, regardless of impedance connected, from 4 ohm to 70V line systems. All inputs and outputs are Crest's Phoenix connectors with level controls in the rear.
There was also the HP-Eight mixing console, available in 24-channel and 32-channel frames as well as installation-size 40, 48 and 56-channel frames. Target markets for the console are medium-capacity live performance venues and houses of worship.
