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.

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.
