The MVX 128 A inputs and outputs VGA video on 15-pin HD connectors and audio
on 3.5 mm, 5-pole captive screw terminals.
The audio switching can be either 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.
The matrix switcher can be remotely controlled via its RS-232/RS-422 port. The
matrix switcher is programmed with Extron's Simple Instruction Set
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 the RS-232/RS-422 link.
The RS-232/RS-422 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 switcher is housed in a rack-mountable, 2U high metal enclosure with
mounting fl anges for standard 19" racks. The appropriate rack mounting kit is
included with the switcher.
The switcher has an internal 100 VAC to 240 VAC, 50/60 Hz, 15 watts
autoswitchable power supply that provides worldwide power compatibility.
The MVX 128 A has a minimum bandwidth of 300 MHz (-3 dB). The switcher can
also switch RGBS, RGsB, RsGsBs, HDTV, component video, S-video, and composite
video.
Defi nitions
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.)
Confi guration — One or more ties or one or more sets of ties.
Current confi guration — The confi guration that is currently active in the
switcher (also called confi guration 0).
Global memory preset — A confi guration that has been stored. Up to 32 global
memory presets can be stored in memory. Preset locations are assigned to
the input buttons and (where necessary) output buttons. Up to 20 presets
can be selected from the front panel for either saving or retrieving. When a
preset is retrieved from memory, it becomes the current confi guration. The
switcher has 32 presets; preset numbers larger than 20 are still accessible
under RS-232/RS-422 control.
