Gain and Equalization Controls

To set up your DA AV EQ, you may need to adjust the gain and equalization (EQ) for the output cable lengths. Gain and EQ are adjusted from the front panel of all DA AV EQ series products except the DA 6A and DA 3AV RCA. On S-video models, you can adjust luma (Y) gain and equalization, and chroma (C) gain. On composite video models, you can adjust Gain and EQ. Adjustments are made for each pair of outputs.

you to make gain and equalization adjustments. Each pot has a white dot either above it (composite and Y gain) or to the lower left of it (EQ and C gain). These dots indicate 0 dB unity.

Use an Extron Tweeker or a small Phillips screwdriver to rotate these pots clockwise to increase gain or equalization, or counterclockwise to decrease.

The DA AV EQ products have one EQ pot and one or two Gain pots for each pair of outputs. Therefore, gain and equalization can be adjusted only for a pair of outputs at a time. For example, if you adjust the equalization pot for output 1, output 2 is automatically adjusted at the same time and by the same amount, .

This means that you should have cables of the same length for both outputs of a pair.

Settings for short cables

At the factory, the DA AV EQ pots are set precisely to the unity gain position (with the arrow on the pot pointing to the dot beside or above it). If you are using very short output cables, do not turn these pots; leave them at the factory default setting. If the pots have already been turned, reset them to the default position. The illustration below shows outputs 1 and 2 set to the unity gain position.
