Russound's KP6 Keypad gives you simple control of your CAA66 multiroom system. It includes 20 source labels to easily identify each system source, from a CD player to an iPod. The keypad also indicates volume and receives IR commands from a remote control. You can adjust the bass, treble, balance, loudness and volume directly from each keypad to personalize the sound in the zone. For added convenience, you can turn the whole system off at any keypad.
