Noise Reduction
You can activate Noise Reduction on demand. It
mutes signal paths when the rig is off-line. The unit
ships with this feature deactivated.
LCD Contrast
Adjust the display’s contrast to taste using the Up
or Down keys. Confirm your selection with Enter.
Factory Reset
When you confirm this function, ALL settings reset
to their factory defaults. For example, you could use
it to set all delays to 0 ms and levels to 0 dB.
Delay Base
Select the preferred delay display reading - meters
(m), feet (ft) or milliseconds (ms). Select the
option with the Up or Down keys and confirm your
selection with Enter.
3.4 Sub Delay
Sub Delay is a time alignment tool, that is, it
compensates differences in mid/high units’ and
subwoofers’ response times. Like Sub Level, Sub
Delay controls subwoofers’ and mid/high units’
relative delay.
For example, if you place subwoofers well in front
of mid/high units, you must delay the subwoofers
accordingly. Do this by adjusting a positive
delay value in the Sub Delay menu. If you place
subwoofers well behind mid/high units, you must
enter negative values to compensate.
Caution: Negative Sub Delay values delay the signal
path from the subwoofer to the mid/high unit,
causing overall system latency! Experience has
shown that this method compensates differences of
15 ms or 5 m without latency problems. The control
range sweeps from -30 ms to 29.6 ms.
3.5 Delay
Delay controls the overall delay of a system
comprised of subwoofers and mid/high units. The
highest setting is 72.6 ms.
3.6 Sub Level
You can adjust the balance of volumes between the
subwoofer and mid/high unit from -12 dB to + 6 dB
in 0.5 dB steps. Use the Up or Down keys to select
the Sub Level and confirm your selection with Enter.
3.7 System Setup
A special filter preset is available for each
configuration (see fig. 19 a-f). Be sure to assign
the same preset to each DDO-PRO™ controller for
every configuration (1 to 4 CTA 208s). Use the Up
or Down keys to select the right preset and confirm
your selection with Enter.
