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.
CAUTION: For unbalanced audio, connect the sleeves to the ground contact. DO NOT connect the sleeves to the negative (-)
contacts.
d RS-232 connector — Connect a host device, such as a computer or control system, to the switcher
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
• See MVX Matrix Switchers User Guide for definitions of the SIS commands and
• Using the hardwired IR input on pin 9, you can use a control system with
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.
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.
details on how to install and use the control software.
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.

Controls and Indicators
NOTE: Smaller matrix sizes have fewer input buttons, output buttons, or both.
a Infrared remote sensor — This sensor receives infrared (IR) signals from the optional IR 501 small matrix universal
remote control. Point the IR remote control within 30 degrees of this sensor for best results. Operation of the switcher
using the IR 501 remote control is described in the IR 501 Small Matrix IR Remote Control User Guide.
b Power/data/audio LED —
When lit, indicates that power is applied to the matrix switcher.
When blinking off and on, indicates that an IR signal has been received.
In Audio Setup mode, serves as an audio meter that is tied to output 1 (see “Viewing and Adjusting the Audio Input
Gain” on page 4).

d Output buttons and LEDs — The output buttons and LEDs select and identify outputs.
NOTES: • The input and output buttons and LEDs also serve as preset selection buttons and indicators, allowing you to select
presets to either save or recall (see “Saving or Recalling a Preset” on the next page).
• The Output 1 through Output 3 LEDs also serve as input audio level indicators, each indicating a range of 6 dB
when lit.
• On 8-output switchers, the Output 7 and Output 8 buttons and LEDs also serve as the Down (<) and Up (>) controls
and indicators. See j and k.
e Enter button — The Enter button saves changes when you set up a new configuration (see “Creating a Tie“ on the next page).
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.
g I/O and Audio Setup button —
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 “Viewing and Adjusting the Audio Input Gain” on page 4).
Audio Setup mode times out after approximately 30 seconds of inactivity.
h Video/+dB LED and Audio/–dB LED —
I/O selection — The Video and Audio LEDs indicate
whether video and audio, video only, or audio only are
selected using the input buttons (c) and output buttons
(d). Pressing the I/O button advances through a cycle of
video and/or audio selection.
Audio Setup mode — The –dB and +dB LEDs indicate the
polarity of the audio level setting (see “Viewing and Adjusting the Audio Input Gain” on page 4). Both LEDs light to indicate
unity gain (0 dB).
i Audio Setup LED — The Audio Setup LED lights red to indicate that the switcher is in Audio Setup mode (see “Viewing and
2
Adjusting the Audio Input Gain” 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.
NOTE: If you wait for the 5-second input/output button timeout to occur after either step 2
or step 3, the entire set of ties is cancelled.
3. Press and release one or more desired output buttons.

Saving or Recalling a Preset
1. To save a preset: Press and hold the Preset button until the Preset LED starts blinking.
To recall a preset: Press and release the Preset button.
2. Press the desired input or output button. The LEDs for the selected input button and
Preset button remain lit for 1 second to indicate the preset and then turn off.

of the selected input has been adjusted to the –10 dBV internal reference level.)
5. For other inputs, repeat steps 3 and 4.
Front Panel Security Lockout (Executive Mode)
The front panel security lockout limits the operation of the switcher from the
front panel and optional IR remote control. When the switcher is locked, the Enter
button, I/O button (video, audio, or video and audio selection), and all of the
front panel audio gain and attenuation functions are disabled. The front panel
input and output buttons continue to allow ties to be viewed, but ties cannot be
created.
The front panel security lockout also disables the IR remote sensor to lock out
remote control functions.
Press and hold the Enter button and the Preset button simultaneously for
approximately 2 seconds to toggle the lock on and off.
