The AV-452 incorporates a microphone mixer, audio/video re- ceiver, infrared controller and digital amplifi er into one affordable, easy- to-use component. As presentation systems and software have become more popular, bing. As devices are selected on the AV-452, IR commands can automatically be forwarded to the video projector, so the presenter only needs to press one switch to change sources. The built-in 100W digital power amp has two switchable speaker outputs, fa- cilitating installations in multi-room setups. The AV-452 can also be cascaded for even more control over multi-room installations. Professional installers will appre- ciate features that make the AV-452 easy to specify and install. A constant voltage input with noise gate allows a pag- ing system to co- exist on the same speaker system as the AV-452. An EMG break can mute local audio when an emergency alarm system is activated, allowing the AV-452 to integrate with common building communication systems. The AV-452 offers a list of conve- nience features for the presenter, from a VGA In/Thru port for laptop connec- tions to a learning IR remote. For even more control, the installer can connect relay switches to a parallel port, or con- nect an AMX™ or Crestron™ system to its’ RS-232/422/485 port. Since A/V systems only enhance a presentation when they run smoothly, the AV-452’s most important feature is to help the presenter. It helps the speaker operate their presentation as one complete unit, increasing their confi dence and allowing them to focus on what they do best. A/V presentations have become routine for middle management, educators and other public speakers. With its universal learning remote and IR blaster func- tions, the AV-452 is designed to control a sophisticated A/V system as a single, integrated unit. The AV-452 was designed primar- ily to assist with switching audio and video sources and to allow presenters to be heard. Four microphone inputs are available on XLR and barrier strips, enough for multiple presenters and au- dience participation. Each microphone input has three-band EQ, level and mute controls, and the installer can switch on a 100Hz rolloff on the mic group. The fi ve A/V inputs are provided for cassette, CD-RW, DVD, VCR and Aux de- vices. The A/V inputs include S-Video and Composite video, and sources can be routed to other destinations for dub-

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.

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.
