About This Manual
This manual provides information on the Extron AVT 100
Analog TV and Cable Demodulator, and discusses how to
install and operate it.
About the AVT 100 Demodulator
The Extron AVT 100 is an audio/video demodulator that
provides cable and television tuning for integration into
professional A/V environments. The TV band provides
reception of over-the-air TV (antenna) and CATV (cable)
channels. Channels 2 through 125 are available in the United
States and other countries that use the NTSC standard.
Channels 48 through 855 are available in countries in which the
PAL standard is used.
N
In Japan, which uses the NTSC standard, channels 1
through 62 (antenna) and 1 through 63 (cable) are
available, on different frequencies from the USA.
The AVT 100 may receive signals from a cable input or TV
antenna. It is controllable from the front panel or through
software via the RS-232 port.
The AVT 100 also provides wired IR for extended range infrared
(IR) operation. The optional AVT 100 IR Remote Control and
the Extron IR Link Signal Repeater are available separately to be
used in conjunction with this feature.
Models
Two models of the AVT 100 are available:
•
AVT 100N (NTSC version)

Handles NTSC signals
only. This version is used in the USA, Japan, and some
other countries.
•
AVT 100P (PAL version)

-based
control software. The optional IR Link is also connected to
this port.
IR Remote Control
— Enables control of the AVT 100 via a
hand-held remote control device that sends infrared
signals to the AVT from a distance of up to 30 feet.
Communication is provided through an infrared receiver
and hard wiring. The Extron IR Link is an option,
available separately.
Balanced and unbalanced audio output
— Enables you to use a
wide variety of output devices without the need for
conversion.
Savable configuration files
— Lets you save the system
configuration as a file. The saved configuration can
subsequently be reloaded to the AVT 100 to restore all
settings at once.
Power supply
— An external desktop 12 VDC power supply
connects to the back panel of the unit via a two-pin captive
screw connector and accepts 100 to 240 VAC.
Enclosure
—
Compact, 1U, quarter-rack enclosure, 6.7 inches in
depth.
Cable/antenna (TV) DIP switch
—
Enables switching between
cable and antenna modes.
99 presets
—
Presets can be associated with channels using SIS
programming, the IR remote control, or the AVT
Windows-based control software. The AVT provides 99
programmable channel presets for TV and 99 for cable.
Stored presets can be used to recall the corresponding
cable or antenna channel in preset mode. With SIS
commands, presets can be recalled in tune mode as well as
preset mode.
Audio and video muting
—
Enables the audio and video
outputs to be individually muted through the appropriate
SIS command, the IR remote, or the Windows-based
control software.
