4. Switching-on and Configuring your
DB1D, DB2D or DB3D Subwoofer
Your DB1D, DB2D or DB3D subwoofer can only be
setup using the Sub app. If you have not already
downloaded and installed the app on your iOS or
Android device please do so now. Bluetooth must
be enabled on the device in order for it to connect to
the DB1D, DB2D or DB3D subwoofer.
Once your DB1D, DB2D or DB3D subwoofer is
positioned in the listening room and connected to
power and signal cables it can be switched on from
its standby button. The standby indicator will change
colour from red to blue. Open the Bluetooth settings
page on your iOS or Android device and select the
DB1D, DB2D or DB3D subwoofer for connection.
Once the iOS or Android device is connected via
Bluetooth, launch the Sub app.
The Sub app will take you through the following
setup parameters so that your DB1D, DB2D or
DB3D subwoofer is fully configured and ready
for use.
• Identification: Enables the DB1D, DB2D or
DB3D subwoofer to be named and the type of
installation (stereo hi-fi or home theatre) to be
specified.
• Audio input setup: Selects the DB1D, DB2D or
DB3D subwoofer input to be used.
• Input Sensitivity: Enables the DB1D, DB2D
or DB3D subwoofer input sensitivity to be
adjusted.
• Polarity Inversions: Enables DB1D, DB2D or
DB3D subwoofer polarity to be inverted to match
the polarity inversion occasionally found in audio
electronics.
• Low Pass Filter: Enables the DB1D, DB2D or
DB3D subwoofer low pass filter to be specified
and engaged or disengaged.
• Impact Equalisation: Enables DB1D, DB2D or
DB3D subwoofer impact equalisation to enhance
the low frequency impact of audio visual material.
• Graphic Equalisation: Enables the DB1D, DB2D
or DB3D subwoofer five-band graphic equaliser
to be adjusted to suit the characteristics of the
listening room.
• Configuration Presets: Enables up to five DB1D,
DB2D or DB3D subwoofer configurations of the
seven setup parameters to be saved as presets.
• Room Optimisation: Enables DB1D, DB2D or
DB3D subwoofer performance to be optimised to
match the acoustic characteristics of the listening
environment. An appropriate OS X or Windows
computer, audio interface, and measurement
microphone is required. Your Bowers & Wilkins
retailer will be ablle to advise on appropriate
hardware.
5. DB1D, DB2D and DB3D In Use
Once the Sub app setup procedure is complete,
your DB1D, DB2D or DB3D subwoofer is ready
for use. Beyond potentially selecting presets for
different types of programme material or selecting
inputs for use with different systems, your DB1D,
DB2D or DB3D subwoofer should need little
regular adjustment. However, if it is moved within
the listening room or if large items of furniture
are introduced, its level and graphic equalisation
will probably require adjustment. If the Room
Optimisation function was previously employed this
will also need to be repeated.
Please remember that DB1D, DB2D and DB3D
subwoofers are capable of volume levels with the
potential to cause nuisance and even damage your
and others’ hearing. If in any doubt, reduce the
volume. If a DB1D, DB2D or DB3D subwoofer is
overloaded its standby indicator will flash red.
The performance of your DB1D, DB2D or DB3D
subwoofer may change subtly during the initial
listening period. If it has been stored in a cold
environment, the damping compounds and
suspension materials of the drive units will take
some time to recover their correct mechanical
properties. The drive unit suspension will also loosen
up during the first hours of use. The time taken for
the speaker to achieve its intended performance will
vary depending on previous storage conditions and
how it is used. As a guide, allow up to a week for
the temperature effects to stabilise and 15 hours of
average use for the mechanical parts to attain their
intended design characteristics.
6. DB1D, DB2D and DB3D Reset
To return your DB1D, DB2D or DB3D subwoofer
to its default settings, switch it to standby mode
(indicator red) then press and hold the standby
button for 5 seconds. The indicator will flash while
a reset is underway. When the reset is complete the
subwoofer will return to standby mode.
7. Cleaning Your DB1D, DB2D or DB3D
Subwoofer
Wipe surfaces with a clean lint-free cloth. If you
wish to use a cleaning agent, apply it onto the
cleaning cloth, not directly onto the subwoofer. Test
a small area first, as some cleaning products may
damage some of the surfaces. Avoid products that
are abrasive, or contain acid, alkali or anti-bacterial
agents.
