ISM Series

Integration Scaling Matrix Switchers with Audio

he Extron ISM Series consists of two Integration Scaling Matrix Switchers: the ISM 182 and ISM 482. Both are

eight input, two output matrix switchers with built-in scalers. All eight inputs are fully configurable for RGBHV,

RGBS, RGsB, component video, S-video, or composite video on female BNCs. The ISM 482 also accepts HDTV to

facilitate future system expansion or projector upgrades. Both models include two independent, high-resolution,

audio/video outputs with built-in, high performance video scalers. The ISM 182 outputs 15 different scaled rates up

to 1024 x 768 while the ISM 482 features 33 scaled output rates up to 1365 x 1024 including HDTV. Each output is

available on a 15-pin HD connector and five BNCs.

The Extron ISM Series combines

switching and scaling in one box—perfect

for applications utilizing two displays

with different resolutions. This would

include presentation applications such

as boardrooms, conference rooms,

classrooms, courtrooms, churches, and

auditoriums. Additionally, the ISM series is

effective in videoconferencing where

multiple sources fed into dual displays is

the norm.

Each matrix also provides switching of

balanced and unbalanced stereo audio on

eight, 3.5 mm captive screw connectors.

Audio signals are, in turn, output

(balanced/unbalanced) on two, 3.5 mm

captive screw connectors. Audio

breakaway is also included and enables the

audio signal to be separated from the

video signal to switch either the video only

or the audio only.

Applications

In one instance, an ISM 482 switcher

may be used in a boardroom that utilizes

an LCD projector with a native resolution

of 1280 x 1024 and a touch-screen control

panel mounted in a podium that accepts

640 x 480. Additional sources may include

a laptop, VCR, DVD player, and document

camera. The second output allows the

presenter to view an input on the touch

panel before switching it over to the main

display. One output of the switcher is able

to scale to the native resolution to the

projector, while the other output is able to

scale to the native resolution to the touch

panel. Unique to the ISM is how it is able

to preview the image at a lower resolution
