Setup Guide — DA AV EQ Series
The Extron
®
DA AV EQ series are distribution amplifiers
(DAs) that are available with composite video or S-video
plus audio, audio only, and video only. They provide
long cable drive capability and individual gain and
equalization adjustment for each output pair. The two
dual models can each be configured to function as two
DAs.
This guide provides basic instructions for an experienced installer to set up and operate these
distribution amplifiers.
Step 1 — Turn off and disconnect all equipment from power source
Step 2 — Mount the unit (optional)
If desired, mount the DA on a 9.5 inches deep or 6 inches deep rack shelf, or on furniture.
Step 3 — Connect video devices (all models except DA 6A)
• Connect video input: Connect a composite video or an S-video source device to the Input
connector. If using a DA 12V/6V or a DA 8V/4V in dual mode, connect input devices to the
Input A and Input B connectors.
• Connect video output: Connect one or more video output devices to the composite video or
S-video output connectors.
Step 4 — Set dual mode toggle switch (Dual EQ models only)
Set the toggle switch for dual or single mode as follows:
• Dual mode: Set the toggle switch down to Dual 1x4 for the DA 8V/4V or
Dual 1x6 for the DA 12V/6V, as shown at right. The DA functions as two
1-input, 8- or 12-output DAs.
• Single mode: Set the toggle switch up to 1x8 for the DA 8V/4V or 1x12
for the DA 12V/6V. The DA functions as a 1-input, 8- or 12-output DA
with active loop-through.
Step 5 — Connect monitor for loop-through (optional)
Connect a monitor to the Loop-Thru connector for passive loop-through, if desired.
For DA 12V/6V or DA 8V/4V Dual EQ models: If the DA will not be used in dual mode,
connect a monitor to the Input B connector for active loop-through, if desired.
Step 6 — Set termination toggle switch
For all models except DA 6A, DA 12V/6V, and DA 8V/4V Dual EQ:
• If a monitor is connected to the Loop-Thru connector, set the Termination
toggle switch up to high Z for passive loop-through, as shown at right.
• If no monitor is connected, set this switch down to 75 Ohm.
Step 7 — Connect audio inputs
Wire the captive screw or RCA input connectors to an audio source as shown below.
