The Extron MMX Series of Video and Audio Matrix Switchers are economical,
compact switchers designed to suit the needs of small composite video and
S-video signal routing applications, such as conference rooms, classrooms, and
home theaters. They are ideal for use as either the primary switcher or as a sub-
switcher in a larger system.

DESCRIPTION
FEATURES (Cont.)
The Extron MMX Series of composite video and S-video matrix
switchers with stereo audio (unbalanced or balanced) consists of eight
models, in 4x2 and 6x2 I/O sizes, for easy integration into any system
design. MMX A/V Series matrix switchers are available with captive
screw or RCA audio connections.
The intuitive front panel buttons and LED indicators enable easy
control of inputs and outputs for non-technical users. MMX A/V Series
matrix switchers can be mounted in standard electronics racks, as well
as within a podium, lectern, or other furniture.
Each model offers vertical interval switching, providing seamless
transitions when switching between synchronous video sources. The
video signal applied to input one is used as a genlock reference. All
models are quad standard compatible for use with NTSC 3.58, NTSC
4.43, PAL, and SECAM format video signals. MMX A/V Series matrix
switchers can be controlled via the front panel or through RS-232 for
use with a third party control system.
FEATURES
■ 150 MHz (-3 dB) video bandwidth, fully loaded – Ensures
switching and distribution of video signals without degradation.
The ratings are worst case specifications, i.e., the MMX Series
provide 150 MHz (-3 dB) at full performance capacity when one
input signal drives all outputs.
■ Buffered I/O – Each input and output is individually buffered to
provide maximum performance with virtually no crosstalk.
■ View I/O mode – Allows users to easily see which individual inputs
and outputs are actively connected. Available from the front panel
or RS-232 control.
■ Vertical interval switching – Provides smooth, seamless transitions
when switching between synchronous video sources. The video
signal applied to input one is used as a genlock reference.
■ Audio input gain and attenuation (adjustable via RS-232) –
Allows users to set the level of audio gain or attenuation for each
audio input channel, eliminating noticeable differences when
switching between sources.
■ Audio breakaway (adjustable via RS-232) – Provides the
capability to break away an audio signal from its corresponding
video signal, allowing the audio channels to be operated as a
separate matrix switcher.
■ RS-232 control port – Using RS-232 serial commands, the unit can
be controlled and configured via the included Windows®-based
control software, or integrated into third-party control systems.
Extron products use the Simple Instruction Set (SIS™) command
protocol, a set of basic ASCII code commands that allow for quick
and easy programming. The RS-232 port also makes it easy to
install firmware updates.
■ Front panel security lockout – Prevents unauthorized use in non-
secure environments.
■ Downloadable firmware updates – The latest firmware can be
conveniently downloaded from the Extron Web site
(www.extron.com). Updates for new features and capabilities can
be easily upgraded via RS-232.
■ Rack-mountable – 1U, half rack width metal enclosure can be
rack-mounted using an optional rack shelf.
■ External international power supply – Provides worldwide power
compatibility (part # 70-055-01).
