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.

from an IR 501, after which it sends the same commands to the MAV 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.
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.
