AV-452
Applications Guide
Two Cascaded Rooms
Single Room in Multiple Zones
S
imilar to the previous example, this installation
shows a hotel conference room with a center
divider. The difference with this installation is that
each room has its own A/V setup. When the two
rooms are joined together, the Cascade button is
pressed on the mixer in room B. This button over-
rides the rest of the settings on the AV-452 in room
B and instead amplifi es the signal from room A.
Both rooms in this example play their audio back
in stereo.
Other applications of the Cascade function
include the ability to use an external submixer
or microphone mixer for large presentations. In
this mode, the AV-452 amplifi es the signal from
the Cascade input in addition to its four mic inputs
and A/V components.
I
t’s not uncommon for a large presentation hall
to need amplifi cation for several zones. Some
examples of exterior zones may be the hallway
outside of a presentation, the restrooms and the
outdoor patio.
In this setup, the AV-452 is connected to a power
amplifi er for use in the main room. The internal
Amp A and Amp B in the AV-452 power the hall-
way and patio zones. If the presenter doesn’t want
his presentation to play in those zones, they can
be turned off without effecting the sound inside
of the room by pressing the Amp A and Amp B
switches.
In this installation, the AV-452’s amplifi ers are
set to mono, but the presentation in the main room
still plays through the power amp in stereo. Like
each of the other installations, the presenter has
instant control over his or her audio and video
sources, and can even switch the projector’s source
from the AV-452’s front panel, learning remote
control or toggle switch controls installed on the
lectern.
