About the MPX 423 A Media Presentation Matrix
Switcher
The MPX 423 A is a matrix switcher that supports both single and separate
switching modes and merges the following independent switchers into a single,
compact enclosure:
• a 4x2 VGA —UXGA matrix switcher
• a 4x2 composite video matrix switcher
• a 4x2 S-video matrix switcher
• a 12x2 stereo audio switcher
The MPX 423 A has the following video connector types:
• 15-pin HD input connectors for VGA signals
• BNC input connectors for composite video signals
• 4-pin mini DIN input connectors for S-video signals
The audio functions use captive screw connectors shared between three input
groups, and support balanced and unbalanced wiring.
There are three device control options:
• Front panel button control
• Ethernet control (using Telnet or the on-board Web server)
• RS-232 control using Extron SIS
™ commands
Features
The features of the MPX 423 A Media Presentation Matrix Switcher include:
Multiple video inputs
— Twelve inputs including four VGA (or SVGA or UXGA
RGBHV, RGBS, RGsB, or RsGsBs) inputs on 15-pin HD female connectors, four
S-video (NTSC, PAL, or SECAM) inputs on 4-pin mini DIN female connectors,
and four composite video (NTSC, PAL, or SECAM) inputs on BNC female
connectors.
Multiple video outputs — Two outputs per video format for simultaneous (in
separate switcher mode), or one at a time (in single switcher mode) display on
VGA, composite video, or S-video devices.
Audio switcher — The 12x2 audio switcher selects among the audio outputs of
each of the three signal groups.
Audio breakaway — The MPX 423 A provides the capability to break away an
audio signal from its corresponding video signal. Audio breakaway switching
can be controlled via the front panel, Ethernet, or RS-232.
Multiple audio inputs and outputs — Twelve balanced/unbalanced stereo inputs
and two balanced/unbalanced stereo outputs, all using captive screw connectors.
Single switcher mode — Allows for one-touch switching. When one of the 12
inputs is accessed, the signals of the input will be routed to the outputs of its
group. Outputs of the other groups are disconnected, while audio output
remains unaffected.
