The wall mounted Volume and Source Control (VSC) features an easy-to-use turn knob for music selection and volume control and also acts as an infrared repeater for source component control. HAI selected a knob design for the VSC because of its elegant, uncluttered style and ease of operation. Simply press the knob to change music sources. Turn it to adjust volume. Press and hold to adjust bass, treble, balance, and turn the
entire system on and off. The blue display shows the source and volume level. For source control, the VSC has routed infrared repeating built in. Simply use your existing remote control to change selections, pause, play, etc. A maximum of 8 VSC's may be installed in a Hi-Fi by HAI installation.
