Crest Audio Pro 8200 High Performance Dual Channel Power Amplifier (Discontinued)

Description

Details

The Pro 200 Series professional power amplifiers offer Crest's renowned sonic integrity while providing exceptionally high power ratings (4500W bridged on the Pro 8200) in a compact, lightweight (under 25 lbs.) 2RU package.

The Pro 200 Series amps feature Automatic Clip Limiting (ACL) to protect connected drivers; IGM Impedance Sensing to accommodate varying impedance outputs; tunnel-cooled, high-efficiency heat sinks and variable-speed DC fans to limit the operating temperature and extend amplifier life.

Autoramp
Gradually increases gain to the attenuator level settings when the amplifier is turned on. This prevents abrupt turn-on level. Other protection features include: short circuit, DC voltage, comprehensive thermal management and current in-rush turn-on/off; transient sub-sonic input.
