1.0 General
Thank you for purchasing Hall Research’s VSA-32 A/V switching control system.
The package is comprised of a 3 input connector panel with a microphone XLR
connector on a 4-gang Wallplate (transmitter), a control panel A/V switcher on a 2-
gang wallplate (user interface) 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. The system also includes a complete Hall
Research Model UVA-WP wallplate transmitter (other compatible UVA senders
will work also).
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), passive 4 or 8 ohm
speakers and a compatible UVA sender unit.
The unit accommodates the following inputs:
• Input #1: PC (VGA to UXGA) or Component (YPbPr) with Mono L+R Audio
Cat5 signal from a compatible remote UVA Sender unit (UVA-2, UVA-4 etc)
• Input #2: PC (VGA to UXGA) or Component (YPbPr) with Stereo Audio
• Input #3: S-Video or Composite Video with Stereo Audio
• Microphone Input via XLR connector or rear 3 Pin Header
The VSA-32 User Interface 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.
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.
