The Extron MMX 42 AV and MMX 42 AV RCA are 4x2 Composite Video and Stereo Audio Mini Matrix Switchers, suitable for applications such as site surveillance with multiple cameras and home theaters. The MMX 42 AV provides stereo audio (balanced/unbalanced) on captive screw connectors, while the MMX 42 AV RCA provides stereo audio (unbalanced) on RCA connectors. Both models include features such as genlock to input one, which allows all signals to switch at the same vertical interval timing for smooth, seamless transition; front panel security lockout for environments where easy access is undesireable; quad standard for switching between NTSC 3.58, NTSC 4.43, PAL, and SECAM for worldwide compatibility; audio breakaway; input audio gain and attenuation; and RS-232 for control via a third party control system. The intuitive front panels with tactile buttons and LED indicators enable easy control of inputs and outputs for non-technical users. MMX switchers are housed in 1U high, half rack width VersaTools™ enclosures.

Features

150 MHz (-3dB) bandwidth, fully loaded – Ensures switching and distribution of most signals without degradation. The ratings are worst case specifications, i.e., the MMX Series provide 150 MHz (-3dB) at full performance capacity — when one input signal drives all outputs.
Buffered I/O – Each input and output is individually buffered to provide maximum performance and virtually no crosstalk.
View I/O mode – Allows users to easily see which individual inputs and outputs are actively connected. Available from the front panel or RS-232 control.
Captive screw or RCA audio connections – The MMX 42 AV provides captive screw input and output connectors for balanced or unbalanced stereo audio signals. The MMX 42 AV RCA model features RCA female connectors and are compatible with unbalanced audio signals only.
Input audio gain and attenuation (adjustable via RS-232 or front panel) –Allows users to set the level of audio gain or attenuation (-18dB to +24dB). Individual input audio levels may be adjusted so there are no noticeable volume differences when switching between sources.
Audio breakaway – The MMX 42 AV and MMX 42 AV RCA provide the capability to break away an audio signal from its corresponding video signal. Audio breakaway switching can be done via front panel control or RS-232 control.
RS-232 control – A rear panel RS-232 control port provides connection of the MMX Series to a third party control system.
Simple Instruction Set (SIS™) – Extron SIS is a set of basic ASCII code commands that provide simple control through a third party control system. Instead of programming in long, obscure strings of code, SIS makes it easy to operate an Extron product using RS-232 control.
Rack-mountable – The MMX Series Switchers are housed in 1U, half rack width rugged metal enclosures and can be rack-mounted using an optional rack shelf.
External international power supply included – Provides worldwide power compatibility. (part# 70-055-01)
