Extron Electronics MAV AV Matrix Switchers Setup Guide - Manual

MAV AV Matrix Switchers • Setup Guide
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.

Video input connectors — Connect up to four or eight S-video or composite video sources.

Hardwired IR
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 may
need to be modified by removing pins or cutting wires. If you encounter problems
while operating under RS-232 control (the switcher may stop responding), 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 MAV 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 MAV via pin 9.
f
Sync connectors — If desired, feed a black burst (genlock) signal to the external sync connectors. SYNC

g
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.
