The CM 2204 amplifier drives 4 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 2RU rack height. A switch allows selection of 0.775 Volt sensitivity or x40 gain. A high-pass filter is selectable per channel.
