The User Interface connects to the Connector Panel via 1 Cat5 cable, to a compatible remote UVA sender via 1 Cat5 cable and sends the selected AV to a remote receiver unit via 2 Cat5 Cables. No power supply is needed for the wall plates. The remote unit can be up to 750 ft away and has a built-in 20 Watt Stereo Amp which can drive a pair of 4 or 8 ohm speakers directly. A line output is provided for connection to an external amp if necessary. A Volume knob on the User Interface wallplate allows adjustment of the sound level of both the AV volume as well as microphone volume. The VSA-32 automatically controls projector operation (on/off and source selection) via serial commands stored in the unit by just the touch of a button.
