Presentation Matrix Switcher.

About the MPX 423 A

The Extron MPX 423 A is a media presentation matrix switcher that merges three

independent matrix switchers into a single, compact enclosure: a 4x2 VGA switcher,

a 4x2 composite video switcher, and a 4x2 S-video switcher. In addition, the

MPX 423 A offers a 12x2 stereo audio switcher. The MPX 423 A supports both single

and separate switching modes.

Ideal for expanding the input capabilities of a typical LCD or DLP projector, the

MPX 423 A provides a second set of outputs for local or preview monitoring, or a

second presentation system.

The MPX 423 A has 15-pin HD input connectors for VGA signals, BNC input

connectors for composite video signals and 4-pin mini DIN input connectors for

S-video signals. Audio uses 5-pole, 3.5 mm captive-screw connectors shared

between three input groups, and features balanced and unbalanced wiring.

The user has a choice of three control options:

1. Front panel touch button control

2. RS-232 using a Windows

-based control program (WCP) or SIS commands

4. Ethernet control (using Telnet, WCP, or the on-board Web server)

Features

Multiple video inputs — Twelve inputs including four VGA (or SVGA, 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 mode), or one at a time (in Single 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 done 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 3.5 mm, 5-pole 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.

Separate Switcher mode — Allows for independent switching to the output of any

given I/O group. This effectively divides the MPX 423 A into three separate

switchers in one box.
