MDA EQ Series Setup Guide
GAIN
The Extron MDA EQ Series are compact mini distribution amplifiers available with
®
composite video or S-video and with individual output gain and equalization controls
that compensate for different cable lengths for each output. Each adjustment on the
MDA 4SV EQ model equalizes two outputs. The MDA EQ products are also line drivers,
able to equalize signals sent over 1000 feet (300 m) of Extron Mini High Resolution cable.
This guide provides basic instructions for an experienced installer to set up these
distribution amplifiers for operation.
Installation
1. Turn off and disconnect all equipment from the power source.
2. (Optional) If desired, mount the MDA EQ on a 9.5, 6, or 3.5 inch deep rack shelf; a
projector mounting pole; or furniture.
3.
Connect a composite video or an S-video source device to the Input connector.
4.
Connect one or two video output devices to the composite video or S-video output
connectors.
5. (Optional) Connect a monitor to the Loop-Thru connector for passive loop-through.
6. Set the termination toggle switch:
о If a monitor is connected to the Loop-Thru connector, set the
switch to High Z (up).
о If no monitor is connected, set the switch to 75 Ohm (down).
