Setting the Audio Output Gain

On the DA 6SVA EQ, DA 6AV EQ, and DA 6A audio models, you can set the gain for the left and right channels independently.

This applies only to models with captive screw audio connectors.

On the internal board, each audio output has a set of jumpers (one left and one right). By placing these jumpers on the appropriate pins on the board, you can set the gain for each channel to -6 dB, 0 dB, +6 dB, or unity, depending on whether the output is wired for balanced or unbalanced audio.

To set the gain for an output channel using the internal jumpers,

1.

Using an Extron Tweeker or other small Phillips

 

screwdriver, remove the six screws from the sides and top

 

of the unit, and carefully lift off the top cover.

2. By default, all jumpers are on the middle and right pins for each output’s right and left channel — the configuration for balanced audio. (See the photograph on the next page.)

Jumpers on the internal board in their default (balanced) position

To change any output channel to unbalanced audio, lift the jumper off the middle and right pins, and place it on the left and middle pins, as shown in the following illustration.
