Bowers & Wilkins DB Series Handbuch Seite 6

• 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.
4.2 Room Equalisation
Note: If two subwoofers are to be set up,
the Room EQ procedure must be carried out
separately for each one.
• To begin the Room EQ procedure select Tune on
home page. Room EQ employs the microphone
in your mobile device to analyse the performance
of the subwoofer in your room, and the initial
requirement is for the mobile device microphone
to be calibrated. This is done by placing the
mobile device in close proximity to one of the
subwoofer drive units while the subwoofer
generates a test signal.
Note: Due to microphone incompatibilities,
Room EQ is not available with all Android mobile
devices. A list of authorised devices can be
found in the support section of the Bowers &
Wilkins website.
• With the mobile device microphone calibrated,
the Room EQ procedure provides options for the
subwoofer optimisation to be targeted at a single
listening position, a listening area appropriate
to two or three listeners, or targeted generally
throughout the room. Choose your preferred
option and select Next.
• The subwoofer will generate a series of eight
separate test signals and use the mobile device
microphone to measure the sound in the room
and automatically apply an optimal EQ curve.
If the Group or Room listening options were
selected the app will ask you to move to different
positions as the eight measurements are taken.
• When the measurements are complete the
results will be displayed. Room EQ will then be
complete. On selecting Next the app will return
to the home page.
If your DB subwoofer is moved within the listening
room or if large items of furniture are introduced, the
Room EQ procedure should be repeated.
