Quick Start Guide

The UI buttons are configured as above when shipped, however 8 of the buttons are

user configurable. So if you don’t have all 5 inputs, you can assign the extra inputs

(and the 2 Auxiliary buttons) for other purposes, such as screen up/down control,

projector lift control, or serial or IR control of other equipment such as DVD players.

Recovering from Audio Amp Shutdown

In rare instances it is possible for the audio amp in the Receiver to shut down due to

an instantaneous over current condition. The amp requires 8 Ω or higher load on each

side. If the load has lower resistance and if you have a large impulse on the audio

input that exceeds several volts, the audio amp will shut-down to protect against

damage. You can recover from this condition using a “Double Mute” procedure

whereby both the mic and the AV source volume are muted at the same time. This will

reset the audio amp and bring it out of shutdown.

Accessories

Several accessories are available with the VSA-51 system. These include:

VSA-MNT

The VSA-MNT is a ceiling projector drop mount with locking

cage. The projector mount is universally compatible with most

down due to over current. To recover from this condition, mute the

microphone and the A/V source simultaneously. This will reset the

amp. Upon un-muting either source, the Amp should be working
