Crest Amplifier CM 2204 Design Focus 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 our CMx accessory. 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...
Most users do not need a license to operate a wireless microphone system.
Nevertheless, operating a microphone system without a license is subject to certain
restrictions: the system may not cause harmful interference; it must operate at a low
power level (not in excess of 50 milliwatts); and it has no protection from interference
received from any other device. Purchasers should also be aware that the FCC is
currently evaluating use of wireless microphone systems, and these rules are subject to
change. For more information, call the FCC at 1-888- CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website at
