Introduction
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:
The switchers are compatible with NTSC 3.38 and 4.43, PAL,
and SECAM video, and feature a 150MHz bandwidth at -3dB,
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™ line
of basic distribution amplifiers, switchers, and video
accessories. They can be mounted to a VersaTools 19” 1U rack
shelf (Extron part #60-190-20) or on a standard Universal Extron
rack shelf (Extron part #60-190-01). They can also be mounted
under a desk or podium, using an under-desk mounting kit
(Extron part #70-212-01). The units ship with external, desktop
12VDC power supplies, which accept 100VAC to 240VAC, 50/60
Hz input.
