AV-452
Single Room Setups
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.
Dual Room Feed
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.
