Volume (GAIN)
With the GAIN control you can adjust the
relative volume level of the subwoofer to
the main speakers of the system:
Play the same track a couple of
times, adjusting the level so that the
instrument sounds homogeneous
across its range.
If you find that at certain specific bass
tones the response is either too loud
(bloated sound) or soft (thin sound), it
may be that you have to experiment
further with the location of the subwoofer
and/or the cross-over settings.
Refer to the sections “Positioning the
subwoofer” on page 20 and “Cut-off
frequencies” on page 25 for further
information.
Cut-off frequencies
Matching the frequency responses
of subwoofer and speakers has an
important impact on the overall sound
quality, when integrating a subwoofer
into a audio-video-system. In general
a large, floor-standing speaker still has
significant output in the deeper bass
range, whereas a very small speaker
will not be able to reproduce deep bass
at all. In the first case a bump in the
overlapping area will cause a louder
or even bloated sound while in the
second case an acoustic hole will be
experienced.
The following figures visualize the
possible results (please note that all
curves are for illustration purposes and
do not show exact filter characteristics).
Note
When using multiple subwoofers,
ensure that the settings for cut-off
frequency, phase and LF extension
are identical. Use the LFE and
Slave mode options to ensure
that all subwoofers operate on the
same settings (refer to chapter
“Multiple subwoofer connections”
on page 13).
Different acoustic loadings can
be found within a listening room.
Thus, balancing out modes may
require different power levels.
