4. Set Up and Control
Your DB Series subwoofer can only be set
up and controlled using the DB Subwoofers
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 subwoofer.
Note: The DB Subwoofers app requires iOS
version 10 and Android version 5 or later.
Bluetooth must be switched on in the iOS or
Android settings.
When your DB subwoofer is connected to
signal cables and mains power it will switch on
in operational mode with its standby indicator
illuminating green. To begin the set up procedure
follow the steps below:
• Launch the DB Subwoofers app and confirm
Bluetooth pairing. When pairing is complete the
app will display the app home page.
• The home page provides subwoofer level
adjustment, product information, auto-standby
options and access to the Room EQ optimisation
procedure. Using Room EQ is not mandatory,
however doing so will ensure that your subwoofer
performs optimally in your room.
4.1 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.
