 Presentation Mixer/Amplifi er

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 
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-
