The PCK-IR and PCK Keypads are state-of-the-art products used to remotely operate the Russound PR-4Zi 4-zone control system. The illuminated, rubber membrane creates excitement in both the look and feel of the buttons.  From any zone, select audio or video source and adjust volume, bass and treble. The PCK-IR has an IR pass-thru, allowing you to control the source equipment from a remote. The PCK has no IR pass-through, and is ideally used in areas where lighting or sunlight would interfere with IR operation, or in small rooms where reaching for the keypad is not an inconvenience.  The PCK-IR and PCK Keypads can be enhanced with the addition of the Russound DSC (Direct Source Control) Keypad and the DAN (Direct Access Numeric) source keypad. The DSC and DAN are IR programmable, allowing up to 12 stored functions for each piece of source equipment. The DAN Keypad allows specific numeric selections of the source equipment to be made, ideal for 100-disc players, satellite receivers, etc.
