SUBWOOFER

Adjusting the subwoofer
To set the adjustable low-pass fi lter
The subwoofer includes a low-pass fi lter which can be adjusted between
40Hz and 150Hz, or disabled using the DEFEAT switch.
1-/ Ê"7
*--Ê/,
If you are connecting the subwoofer to a digital surround processor that
provides its own crossover, such as a Meridian digital surround processor,
set the low-pass fi lter switch to DEFEAT.
If you are connecting the subwoofer to an analogue preamplifi er or
surround processor, set the low-pass fi lter to the middle of its range, and
then listen to a sweep tone from the processor if it provides one, or
alternatively from a test disc, and make sure the bass is smooth throughout
the range.
If there is a peak in the bass loudness, the subwoofer may be adding to the
bass from your main speakers, in which case reduce the low-pass fi lter
frequency.
Likewise, if there is a dip in the bass loudness, increase the low-pass fi lter
frequency.
To set the gain
The GAIN control allows you to adjust the loudness of the subwoofer to
suit the other components in your system.
For the best signal to noise ratio, adjust the level of the subwoofer using
the level control on the subwoofer. If you are using a Meridian Digital
Surround Processor, you can then use the processor’s calibration option to
fi ne-tune the subwoofer level if necessary.
If your surround processor or preamplifi er does not include a Calibration
option, listen to familiar source materials and adjust the gain until the bass
sounds solid and deep, but not boomy or intrusive.
