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	Description
model
MMX 42 AV	4 x 2 composite video (BNC) and audio
	(captive screw) switcher
MMX 42 SVA	4 x 2 S-video (4-pin mini DIN) and audio
	(captive screw) switcher
MMX 42 AV RCA	4 x 2 composite video (BNC) and audio
	(RCA) switcher
MMX 42 SVA RCA	4 x 2 S-video (4-pin mini DIN) and audio
	(RCA) switcher
MMX 62 AV	6 x 2 composite video (BNC) and audio
	(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.
