4.2 Input Set up
• Selecting the Input option from the app home
page will open a configuration page that enables
the Phono and XLR inputs to be independently
set up. Selecting one of the inputs also makes
it active.
Note: The set up options available for the XLR
and Phono inputs are the same.
Note: Settings are input specific. Different
settings can be selected for each input.
Note: If two subwoofers are used in one system
the input settings should be the same for both.
• The input set up options are described in the
following paragraphs:
• Connection: None, Stereo, LFE.
If your subwoofer is to be used for the low
frequency effects channel in a home theatre
system select LFE. If your subwoofer is to be
used for low frequency enhancement of stereo
speakers select Stereo. If the input is not
connected select None.
• Trim: Input sensitivity.
Begin with the input sensitivity set to 0dB. If, in
use, the subwoofer level adjustment on the app
home page doesn't provide a suitable range the
level trim can be adjusted.
• Input EQ: Flat (no EQ), Music, Movie, Custom.
Select Flat to apply no input EQ. Select Music to
apply an input EQ character appropriate for music
programme. Select Movie to apply an input EQ
character appropriate for movie programme.
If the Custom input EQ option is selected the
app will display a five band EQ page that enables
a custom equalisation curve to be applied to the
input signal.
• Stereo Settings: Configure.
The Stereo Settings option is available only if the
Stereo input connection option is selected. In this
case, selecting Configure will open a page that
enables either the subwoofer's low pass input
filter to be set appropriately for specific Bowers
& Wilkins main speaker models, or enables a
custom low-pass input filter to be specified.
• Use of a custom low pass filter is appropriate
when either the main speakers are unlisted
Bowers & Wilkins models, or are from an
alternative manufacturer. In either case, the
low pass filter should be configured to match
the main speaker's published low frequency
characteristics. Bowers & Wilkins or the
alternative speaker manufacturer will be
able to assist with the appropriate information
if necessary.
