• DA 6SV EQ, DA 6SVA EQ, and DA 6SVA RCA EQ —
The front panels of these models each contain one Y Gain,
one Y EQ, and one C Gain potentiometer for each pair of
outputs. The illustration below shows the Y Gain, EQ,
and C Gain potentiometers for outputs 1 and 2.

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.

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.
Gain and EQ potentiometers (pots) on the front panels enable
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.
• DA 6V EQ, DA 6AV EQ, DA 6AV EQ RCA,
DA 8V/4V Dual EQ, and DA 12V/6V Dual EQ
— The
front panels of these models feature one Gain and one EQ
pot for each pair of outputs. The illustration below
shows the Gain and EQ pots for outputs 1 and 2.
