The MVX A switchers input and output VGA video on 15-pin HD connectors and audio on 3.5 mm, 5-pole captive screw terminals.

The audio switching can either be linked with the video (audio follow) or be independent of the video (audio breakaway). Adjustable input audio gain and attenuation compensates for level differences between audio inputs.

Each matrix switcher can be remotely controlled via its rear panel RS-232/RS-422 Remote port and its front panel Configuration (RS-232) port using either Extron’s Windows®-based Matrix Switchers Control Program or the Simple Instruction Set (SIS). The SIS is a set of basic ASCII code commands that provide simple control through a control system or PC without programming long, obscure strings of code. SIS commands can be entered via either serial port.

Either serial port can be connected to and operated from:

A control system

A PC

An Extron MKP 2000 remote control panel

An Extron MKP 3000 remote control panel

An Extron MCP 1000 remote control panel and/or MKP 1000 remote keypad

The matrix switchers are housed in rack-mountable, 2U (MVX 128 VGA A) or 3U (all other models) high metal enclosures with mounting flanges for standard 19" racks. The appropriate rack mounting kit is included with each switcher.

The switchers have an internal 100 VAC to 240 VAC, 50/60 Hz, 30 watts autoswitchable power supply that provides worldwide power compatibility.

The MVX A switchers have a minimum bandwidth of 300 MHz (-3 dB). The switchers can also switch RGBS, RGsB, RsGsBs, HDTV, component video, S-video, and composite video.

Definitions

The following terms, which apply to all Extron matrix switchers, are used throughout this manual:

Tie — An input-to-output connection

Set of ties — An input tied to two or more outputs. (An output can never be tied to more than one input.)

Configuration — One or more ties or one or more sets of ties

Current configuration — The configuration that is currently active in the switcher (also called “configuration 0”)

Global memory preset — A configuration that has been stored. Up to 32 global memory presets can be stored in memory. Preset locations are assigned

to the input buttons and output buttons. When a preset is retrieved from memory, it becomes the current configuration.

The switchers have 32 presets. On the MVX 128 VGA A, up to 20 presets can be selected from the front panel for either saving or retrieving. Preset numbers larger than 20 are accessible via serial port control.
