1.0 General

Thank you for purchasing the Hall Research Model VSA-31-SP A/V
switching control system. The package is comprised of a 3 input
connector panel with a microphone XLR connector on a 4-gang Wall plate
(transmitter), a control panel A/V switcher on a 2-gang wall plate (user
interface) plus a remote receiver with video, audio, serial control outputs,
and a serial programming cable are also included in the package.

This device can be 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-SP provides individual buttons for turning the projector
on/off, volume control selection, selecting the video source for display as
well as a user defined „AUX‟ button. It connects to the Connector Panel
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 (10x2)
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 wall plate allows adjustment of the
sound level of both the AV volume as well as microphone volume. The
VSA-31-SP 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 User interface unit is located on a wall or
panel and is wired to the connector panel via 1 CAT5 cable. The
connector panel is wired to the receiver unit via 2 CAT5 cables.

The user interface and connector panels qualify as low-voltage class 2
devices and do not require a J-box in the wall. 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 standard 2-gang and 4-gang electrical boxes in order to attach the
faceplates to the mounting surface or structure.

Please contact Hall Research or your desired electrical supply house for
purchasing the J-box. These are generally inexpensive units.
