4x2 Composite Video and Stereo Audio Matrix Switchers

 - 150 MHz (-3 dB) bandwidth. fully loaded — Ensures switching and distribution of video signals without degradation. The ratings are worst case specifications. i.e.. the MMX matrix switchers 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.
 - Audio input gain and attenuation — Allows users to set the level of gain or attenuation for each audio input channel. eliminating noticeable differences when switching between sources.
 - RS-232 control port — Using serial commands. the MMX 42 AV can be controlled and configured via the included Windows-based control software. or integrated into a control system. Extron products use the SIS™ - Simple Instruction Set command protocol. a set of basic ASCII code commands that allow for quick and easy programming. The RS-232 port also makes it easy to install firmware updates.
 - View I/O mode — Allows users to easily see which individual inputs and outputs are actively connected.
 - Inputs: Video on female BNC connectors; audio on captive screw connectors or RCA jacks
 - Outputs: Video on female BNC connectors; audio on captive screw connectors or RCA jacks
 - 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 jacks and are compatible with unbalanced audio signals only.
 - Audio breakaway — Provides the capability to break an audio signal away from its corresponding video signal. allowing the audio and video signals from one source to be switched to different destinations.
 - 1U. rack-mountable. half rack width metal enclosure — Can be rack-mounted using an optional rack shelf.
 - External universal energy efficient power supply included. part # 70-775-01 — Provides worldwide compatibility. low power consumption. and reduced operating costs.
