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-
