Two Cascaded Rooms

Similar 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 amplifies 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 amplifies the signal from the Cascade input in addition to its four mic inputs and A/V components.

Single Room in Multiple Zones

It’s not uncommon for a large presentation hall to need amplification 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 amplifier 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

In this installation, the AV-452’s amplifiers 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
