Velodyne Digital DrivePLUSSeries - Manual (Page 32)

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 and Windows interfaces.
Contour Frequency No No Frequency that can be set in increments of 1 Hz between
15 Hz and 200 Hz to boost or cut the signal (contour) of
your subwoofer‘s frequency response at that frequency.
The contour filter acts as an “extra” user-set EQ that can
be used to manipulate the subwoofer frequency response
when a particular preset is invoked. The subwoofer’s Setup
preset parameters don’t include those for the contour
filter as each contour filter is a subset of each of the
other presets.
Contour Level No No A preset’s contour filter’s amount of boost or cut added at
the contour frequency. + 6 dB is the maximum boost.
-13 dB is the maximum cut. The contour level is like
changing the volume at only one bass frequency.
Theater / Music Indicator No No Sets the accelerometer servo gain of the digital servo
system between 1 and 8. The 1 setting is for the least
amount of servo gain or allowing some distortion; this
setting might be more appreciated for media with less
accuracy required, such as movies or games. The 8 setting
is for the most amount of servo gain or least amount of
distortion; this setting would be used more for critical
listening of music. We prefer using 8 for the theater preset,
but feel free to customize it if you like.
The somewhat higher distortion of the 1 setting during
playback makes explosions and other theatrical and gaming
content have an overall louder and more impressive bass
