1.0 General
Thank you for purchasing Hall Research Technologies’ VSA-31 A/V
switching control system. The package is comprised of a 3 input A/V
switcher on a 4-gang wallplate (transmitter) plus a remote receiver with
video, audio, and serial control outputs, a serial programming cable as
well as a Windows™ Software disk are also included in the package.
This device is used to add audio video capability to any room. The
installer need only supply the display device (such as a projector) and
passive 4 or 8 ohm speakers.
The unit accommodates the following inputs:
• Input #1: PC (VGA to UXGA) or Component (YPbPr) with Stereo Audio
• Input #2: PC (VGA to UXGA) or Component (YPbPr) with Stereo Audio
• Input #3: S-Video or Composite Video with Stereo Audio
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 2 Cat5 Cables. No power supply is needed for the
wallplate. The remote unit can be up to 750 ft away and has a built-in 12
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 wallplate 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.
