Designed to add high-end A/V capabilities to any classroom or conference room, the VSA-31-SP integrates A/V switching, microphone input, projector control, video transmission over UTP, and audio amplification in one package.
The VSA-31-SP is comprised of a user interface, configured as a 2-gang wallplate, a transmitter, configured as a 4-gang wallplate, and a small receiver.
The user interface provides individual buttons for controlling the projector power on/off as well as selecting the video source from among 2 PCs or a TV (S-Video / Composite).
The user interface wallplate also features a volume knob for adjusting the audio level independently for each input and the microphone audio level. No power supply is needed for either wallplate since power is supplied via the Cat5 cables from the remote receiver unit.
The unit sends the selected input source to a receiver via 2 Category 5 cables up to 750 feet (230 m) away. The system features a built-in 20 Watt (10 x 2) stereo audio amplifier to drive 4 or 8 Ohm speakers directly. The receiver has a serial output port that connects to the projector and it automatically issues user programmable control commands for power on/off and source selection. The unit also features relay contacts that can control remote items such as lighting or video screens.
The Model VSA-31-SP supports resolutions up to 1920 x 1440 and features automatic long-cable compensation for any length of UTP cable. In addition to its built-in audio amplifier, the remote receiver features line-level audio output for connection to an external audio amp if required.
