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:
MMX switcher

4 x 2 composite video (BNC) and audio
MMX 42 AV
(captive screw) switcher
4 x 2 S-video (4-pin mini DIN) and audio
MMX 42 SVA

6 x 2 composite video (BNC) and audio
MMX 62 AV
(captive screw) switcher
6 x 2 S-video (4-pin mini DIN) and audio
MMX 62 SVA
(captive screw) switcher
6 x 2 composite video (BNC) and audio
MMX 62 AV RCA
(RCA) switcher
6 x 2 S-video (4-pin mini DIN) and audio
MMX 62 SVA RCA
(RCA) switcher
The switchers are compatible with NTSC 3.38 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 are part of the VersaTools
of basic distribution amplifi ers, switchers, and video accessories.
They can be mounted to an optional VersaTools 19" 1U rack
shelf, a 6" rack shelf, or a standard 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.
