The MAV AV matrix switchers distribute broadcast quality composite video or S-video signals,
depending on the model, 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

NOTES: • The figures above show all connector types that you may have on your switcher.

• S-video models use 4-pin mini-DIN female connectors for video.

• Composite video models use BNC female connectors for video.

• Audio models use either 3.5 mm, 5-pole captive screw connectors (“A” in the product name) for balanced or

unbalanced audio or RCA female connectors (“A RCA” in the product name) for unbalanced audio only.

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

a Video input connectors — Connect up to four or eight S-video or composite video sources.
b Video output connectors — Connect up to four or eight S-video or composite video displays.
c Audio input connectors — Connect up to four or eight stereo audio sources. See below to wire captive

screw connectors.

d Audio output connectors — Connect up to four or eight stereo audio devices, such as an audio amplifier or

powered speakers. See below to wire captive screw connectors.

CAUTION: For unbalanced audio output, connect the sleeves to the ground contact. DO NOT connect the sleeves to the

negative (-) contacts.

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.

NOTE: By default, this sensor is disabled (see “Selected SIS Commands“ on page 4 to enable it).

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).

c Input buttons and LEDs — The input buttons and LEDs select and identify inputs.
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 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
simultaneously 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 Universal 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.

NOTES: • On 8-output switchers, this button and LED are secondary functions of the Output 7 button and LED.

• The < LED flashes once in Audio Setup mode to indicate each 1 dB decrease in the input audio gain (see “Viewing

the adjustment has reached the maximum gain (+10 dB).

Operation

Powering Up

Plug the switcher into an AC power source. 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 (LED lit) or deselect (LED 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.

4. Press and release the Enter button. The LEDs for the selected input and the selected outputs light steadily for

Saving or Recalling a Preset

1. Select a preset to save or recall:

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 to save or recall the preset.

The LEDs for the selected input button and Preset button remain lit for 1 second to
indicate the preset and then turn off.

Press and release the Input 1 button

Viewing and Adjusting the Audio Input Gain

1. Apply audio signals to all inputs to be adjusted.

2. Press and hold the Audio Setup (I/O) button for 2 seconds until the Audio LED lights.

4. Increase and decrease the audio input gain by pressing the > and < buttons until the audio

indicator (power LED) blinks frequently. (The power LED blinks frequently when the audio level
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.
