MVX Matrix Switchers • Setup Guide
The MVX VGA matrix switchers distribute high resolution video and stereo audio input signals to
any combination of outputs. The matrix switcher can route multiple input/output configurations
simultaneously. The switchers are available in four matrix sizes:
z z4 inputs by 4 outputs 4 inputs by 8 outputs
z z8 inputs by 4 outputs 8 inputs by 8 outputs

Video inputs — Connect up to four or eight analog computer-video sources to these 15-pin HD female
connectors.
Audio inputs — Connect up to four or eight unbalanced stereo audio sources to these 3.5 mm mini stereo jacks for unbalanced
audio input.
b — Connect up to four or eight RGBHV high resolution video displays to these RGB video output connectors
15-pin HD female connectors.
NOTE: The MVX switchers can also switch RGBS, RGsB, RsGsBs, component/HDTV video, S-video, and composite video.
Some video sources may require adapters.
c — Connect up to four or eight balanced or unbalanced stereo audio devices, Balanced or unbalanced audio output connectors
such as an audio amplifier or powered speakers, to these 3.5 mm, 5-pole captive screw connectors.

via this 9-pin D connector for remote control of the switcher. See the pinout drawing at right.
NOTES: The cable used to connect the RS-232 port to a computer or control system
•
may need to be modified by removing pins or cutting wires. If you encounter
problems while operating under RS-232 control (the switcher may hang up), pins
1, 4, 6, 7, and 8 may need to be disconnected. Either cut the wire to pins 1, 4, and
6 through 8 in a hard-shelled connector or remove pins 1, 4, and 6 through 8 from
a molded plug.
•See for definitions of the SIS commands and MVX Matrix Switchers User Guide
details on how to install and use the control software.
•Using the hardwired IR input on pin 9, you can use a control system with
IR-learning capabilities to operate the switcher just as if you were using an IR 501
remote control. The control system must first “learn” the IR command from an
IR 501, after which it sends the same commands to the MVX via pin 9.
e — Plug a standard IEC power cord into this connector to connect the switcher to a 100 VAC to 240 VAC, AC power connector
50-60 Hz power source.

f Preset button and LED — The Preset button activates either Save Preset mode or Recall Preset mode. Save Preset mode saves a
configuration as a preset. Recall Preset mode recalls and activates a previously-defined preset. The Preset button indicates Save
Preset mode when it is blinking and Recall Preset mode when it lights steadily.

Press and release — Cycles through video and audio, video only, or audio only for input and output selection. See the Video and
Audio LEDs (h) for the sequence.
Press and hold — The I/O button also serves as the Audio Setup mode selection button. To enable the Audio Setup mode, press and
hold the Audio Setup button for about 2 seconds until the Audio Setup LED (i) lights. In Audio Setup mode, you can view and
change the current audio level setting for each input (see “ ” on page 4).

NOTE: The Audio Setup LED also indicates errors when you use an IR 501 small matrix remote control. The LED lights for
approximately 1 second when the switcher receives an unexpected or out-of-sequence IR command from the remote
control. The switcher otherwise ignores the command.

Operation
Powering Up
Plug in the switcher to apply power. The switcher performs a self-test that sequences the front panel LEDs. After the self-test, video
and audio are selected and the configuration and audio settings are the same as they were when power was removed.
Creating a Tie
1. Press and release the I/O button to select (lit) or deselect (unlit) the Video LED, audio LED, or both as desired.
2. Press and release the desired input button.
