The VSA-31 Switch-Cat® created by Hall Research is a 3-input A/V Switcher and transmitter paired with a remote receiver. The VSA-31® provides individual buttons for turning the projector on/off and selecting the video source for display. It sends the selected AV to a remote receiver unit via Cat5 Cables. No power supply is needed for the sender.
The remote unit can be up to 750 ft away and has a built-in Stereo Amp which can drive a pair of 8 or 16 ohm speakers directly. A volume knob on the sender allows adjustment of the sound level. The VSA-31® automatically controls projector operation (on/off and source selection) via serial commands stored in the unit by just the touch of a button.
