AV-452 
Applications Guide
Single Room Setups
Dual Room Feed
T
his 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 amplifi er 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 amplifi er, but also as a video 
switcher and master controller for the system. 
H
otel conference rooms commonly employ fold-
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 
room’s amplifi er off on the AV-452. 
If the client needs two stereo feeds for mul-
timedia presentations with this setup, you can 
add an external power amplifi er for room A, use 
the internal amps for room B, and have the same 
individual control over the two rooms.
