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.
