Model VSA-31
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.

3.0 Installation
In a typical installation, the Sender unit is located on a wall or panel and
is wired to the remote Receiver unit via 2 Cat5 cables.
The sender qualifies as a low-voltage class 2 device and does not require
a J-box. In fact it does not even need a power supply to be connected to it,
as it draws power via the signal connection to the remote unit. However,
in most instances it is easier to use a standard 4-gang electrical box in
order to attach the faceplate to the mounting surface or structure.
Please contact HRT or your desired electrical supply house for purchasing
the J-box. These are generally inexpensive units.
