OPTImIZATION
Digital Servo User’s Manual
Typically, during Manual-EQ these parameters are the same
for all the presets. However if your media is so demanding
and varied for different listening modes, you might want to
set these filters individually for each preset.
Phase No No Adjust the phase delay of your subwoofer’s output signal
from 0° to 180° in 15° increments to allow a better blend
to the satellites at crossover and account for distance or
delay differences. During Manual-EQ, we recommend you
adjust the polarity before adjusting the phase.
Polarity No No Your subwoofer’s polarity can be either positive (+) or
(+/-) negative (-). Toggling between these settings reverses the
audio signal’s phase 180 degrees. This can be helpful with
extreme placements, certain crossover slopes or blending
to main speakers driven by amplifiers with inverted polarity.
Volume No No During Manual-EQ, you can set the volume level from 1 to
(1-99) 99 for each preset (1-5) separately from the Setup preset
(the 0 or global preset) volume. The Setup preset volume
can be changed permanently or temporarily using the
TV screen interface or temporarily using the volume
control on the remote or the volume knob on the front
of the subwoofer. If the change made by the volume
control on the front or on the remote is desired to be
permanent, you must enter the TV screen interface’s
setup menu and select to save and exit. Otherwise,
the new volume setting will be lost upon turning off
power to the subwoofer.
The factory default presets include volume difference from
the Setup preset volume per the character of the preset.
This difference helps identify the preset audibly, but can be
changed. Each preset increments its volume in accordance
with any changes of the subwoofer volume, keeping these
differences intact. For example, if the subwoofer is set to
the jazz preset (preset 3) and shows a volume of 30
because the Setup preset volume is 30 and the Theater
preset (preset 1) volume is 40, selecting preset 1 raises the
volume to 40. If the VOL+ key on the remote is then used to
increase the volume to 45, and then the jazz preset (preset
3 – same level as the Setup preset) is selected, the
subwoofer will display a volume of 35. These volume
differences can be seen in the preset volume line in the
TV screen interface.
