Crest CM 2204 4-Channel Power Amplifier - 220 Watts per Channel

The CM amplifier series drives 4 or 8 independent channels into low impedance or 70 Volt 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 8 channels in a space-saving 2U rack height. A switch allows selection of 0.775 Volt sensitivity or x40 gain. A high-pass filter is selectable per channel. 100 and 50 Volt operation is supported with Crest Audio CMx accessory.

Features:

• Power into 4 Ohm - 150 W x 4
• Power into 8 Ohm - 220 W x 4
• Power @ 70V - 220 W x 4
• 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(tm) (Active Clip Limiting) automatically reduces gain at the onset of clipping to prevent amplifier and load damage
• IGM(tm) (Instantaneous Gain Modulation) monitors load current to protect against overloading
• AUTORAMP(tm) 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
