This simple setup shows the AV-452 at the cen- ter of a single room setup. This is a common arrangement for boardrooms, small churches and school presentation rooms. Mic panels in the walls allow up to four microphones to be connected to the AV-452, or wireless microphones can be connected in their place. The DVD player and Cassette/CD-RW combo are connected to their dedicated inputs and can be switched from the AV-452’s front panel or

learning remote control.

The AV-452’s internal 100W amplifier provides power for the distributed speaker system. A con- stant voltage input allows the building’s intercom system to be wired directly into the mixer, so the presenter can turn off background music during presentations. A gate on the CV line can still pass announcements and emergency alerts.

In this case, the AV-452 functions not only as a small PA and A/V amplifier, but also as a video switcher and master controller for the system.

Dual Room Feed

Hotelconferenceroomscommonlyemployfold- ing partitions so that the room can be divided for two smaller events. A hotel with modest needs

can use a single AV-452 in this joined setup.

The A/V equipment is placed in Room A,and will only be available in that room. When the partitions are open, both Amp A and Amp B are switched on from the AV-452’s front panel. When a small group needs to use room B and the partition is closed, Amp B is switched off. The installer can even wire a toggle switch to the wall in room B to switch that

If the client needs two stereo feeds for mul- timedia presentations with this setup, you can add an external power amplifier for room A, use the internal amps for room B, and have the same individual control over the two rooms.
