The CM 2204 300W Power Amplifier drives 4 independent channels into low impedance or 70V loads. With this advanced amplifier architecture, there is no need to select the load impedance. Each channel can drive 4 ohms and up for flexible system configuration. Sonics are outstanding, and the price enables use in a multitude of applications. High efficiency allows up to 4 channels in a space-saving 2U rack height. A switch allows selection of 0.775V sensitivity or x40 gain. A high pass filter is selectable per channel. 100V and 50V operation is supported with the CMx accessory (sold separately).

Crest Audio's CM Series amplifiers open new horizons for professionals requiring a sonically superior, multi-channel amplifier. Any where performance, functionality and rack space economy are system design considerations such as: bars/clubs/restaurants, video conferences systems, hotels/motels, industrial, or retail stores.

FEATURES
  • Power into 4 Ohm - 150 W x 4
  • Power into 8 Ohm - 220 W x 4
  • Power @ 70V - 220 W x 8
  • Multi-load architecture allows low impedance or 70 Volt operation without select switch (100 or 50 Volt output operation with CMx accessory)
  • Low mains current draw
  • Compact design allows up to 8 channels in a 2U rack space
  • Low weight
  • Cost-effective for many multi-channel applications
  • Flexible configuration
  • Easy set-up
  • CM Series Protection Circuits
  • ACL (Active Clip Limiting) automatically reduces gain at the onset of clipping to prevent amplifier and load damage
  • IGM (Instantaneous Gain Modulation) monitors load current to protect against overloading
  • AUTORAMP gradually increases gain when the amplifier is turned on, preventing abrupt turn-on level
  • Other protection features include: short circuit, DC voltage, comprehensive thermal management, current in-rush turnon/off transient and sub/ultrasonic input
  • Five-year warranty
