Designed for the special needs of meeting rooms, conference halls, churches and other presentation ap- plications, the TASCAM AV-452 is an all-new mixer created for the needs of the contracting and installation market. The AV-452 incorporates a microphone mixer, audio/video re- ceiver, infrared controller and digital amplifier into one affordable, easy- to-use component.

As presentation systems and software have become more popular,

A/V presentations have become routine for middle management,educators and otherpublicspeakers.Withitsuniversal 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 inputhasthree-bandEQ,levelandmute controls,and the installer can switch on a 100Hz rolloff on the mic group.

The five 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-

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 confidence and allowing them to focus on what they do best.
