About the MMX 42/62 Series Matrix Switchers
The Extron MMX 42/62 series of compact matrix switchers
consists of four models of 4-input, 2-output video and audio
matrix switchers, and four models of 6-input, 2-output video
and audio matrix switchers, including the following:

(captive screw) switcher
MMX 62 AV RCA
6 x 2 composite video (BNC) and audio
(RCA) switcher
The switchers are compatible with NTSC 3.58 and 4.43, PAL,
and SECAM video, and feature a 150 MHz bandwidth at -3 dB,
fully loaded. When external sync is applied (to Input 1), video
switching occurs during the vertical interval, providing glitch-
free switching when all sources are genlocked.
All models feature front panel controls as well as an RS-232
connector (3-pin captive screw) to permit external remote
control.
The MMX 42 switchers distribute any of four video and/or
audio inputs to either or both outputs. The MMX 62 switchers
distribute any of six video and/or audio inputs to either or
both outputs. Any input can be switched to either or both
outputs. The RCA models route unbalanced stereo audio and
the AV and SVA models route balanced or unbalanced stereo
audio. The audio switching can either be linked with the video
(audio follow) or independent of the video (audio breakaway).
Adjustable audio gain and attenuation (available via RS-232
control) compensates for level differences between audio inputs.

These half-rack width switchers can be mounted to an optional
3-inch deep 1U rack shelf, a 6-inch deep rack shelf, or a standard
9.5-inch rack shelf. They can also be mounted under a desk
or podium, using an optional under-desk mounting kit. See
appendix A, "Reference Information", for all mounting kit part
numbers. The units ship with external, desktop 12 VDC power
supplies, which accept 100 VAC to 240 VAC, 50/60 Hz input.
Features
Composite video (AV) models
Inputs — Composite video switchers accept up to four
(MMX 42) or six (MMX 62) composite video inputs on
BNC female connectors.
Outputs — Two composite video signals are output on BNC
female connectors.
S-video (SV) models
Inputs — S-video switchers accept up to four S-video inputs
(MMX 42) or six S-video inputs (MMX 62) on 4-pin mini
DIN connectors.
Outputs — Two S-video signals are output on 4-pin mini DIN
connectors.
