Extron electronic Stereo Amplifier DA AV EQ User Manual

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:
