Crest Audio Introduces CM™ Series Power Amplifiers

Crest Audio proudly introduces the new CM Series industrial power amplifiers, ideal for multi-channel applications in nightclubs, restaurants, hotels, retail stores and video conferencing systems.

The four-channel CM 2204 and eight-channel CM 2208 feature an advanced amplification architecture that allows low impedance or 70 Volt operation at the same power levels without switching. Each amplifier in the chassis will operate to rated power, regardless of impedance connected, from 4 Ohms to 70 Volt line systems. The design centers around an ultra-high efficiency output circuit, lowering the line current required for a given output power by as much as 50%. All inputs and outputs are on Phoenix(TM) connectors with level controls in the rear.

CM Series power amps include multiple protection circuits, such as ACL(TM) Active Clip Limiting, which automatically reduces gain at the onset of clipping to prevent amplifier and load damage; IGM(TM) Instantaneous Gain Modulation, which monitors load current to protect against overloading; AUTORAMP(TM) to prevent abrupt turn-on levels by gradually increasing gain when the amplifier is switched on; as well as short circuit, DC voltage, comprehensive thermal management, current in-rush turn on/off transient and sub/ultrasonic input.

A switch allows selection of 0.775V sensitivity or x40 gain. A high pass filter is selectable per channel, and 100 Volt and 50 Volt operation is supported with our CM100V and CM50V accessories.

The CM Series will be available in Q1 2005 from authorized Crest Audio dealers.
