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 4 inputs by 4 outputs z 4 inputs by 8 outputs

z 8 inputs by 4 outputs z 8 inputs by 8 outputs

NOTE: Smaller matrix sizes have fewer input connectors, output connectors, or both.

a Video and audio inputs —

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 RGB video output connectors — Connect up to four or eight RGBHV high resolution video displays to these

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 Balanced or unbalanced audio output connectors — Connect up to four or eight balanced or unbalanced stereo audio devices,

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 MVX Matrix Switchers User Guide for deﬁnitions of the SIS commands and

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 AC power connector — Plug a standard IEC power cord into this connector to connect the switcher to a 100 VAC to 240 VAC,

50-60 Hz power source.

j Down (<) button and LED — The < button decreases the audio gain for a selected input. Press and release the button to decrease the gain by 1 dB or press and hold the button to decrease the gain by 3 dB per second until the button is released or the lower limit is reached. NOTES: • On 8-output switchers, this button and LED are secondary functions of the Output 7 button and LED.
