Subwoofer and centre
speaker
You can connect a subwoofer and a
centre speaker to this device.
In order to optimise the sound still fur-
ther when using a subwoofer and cen-
tre speaker, you can set a low-pass fil-
ter for the subwoofer and a high-pass
filter for the front and rear channels sep-
arately.
Adjusting the subwoofer boost
level (gain)
You can set a permanent volume boost/
reduction level between -6 and +6 for
the connected subwoofer and therefore
emphasise or tone down the subwoof-
er’s bass reproduction. The setting that
you should select depends on the in-
stallation position and location of the
subwoofer in your vehicle. If necessary,
find out which setting you prefer by try-
ing out the various settings.

Setting up the low-pass filter
You can use the low-pass filter to set a
frequency up to which the subwoofer
will work. All the signals above the set
frequency will be “cut off” and not sent
to the subwoofer.
You can choose between the following
frequencies: “40 Hz”, “50 Hz”, “63 Hz”
and “100 Hz”. If your subwoofer is fitted
with a built-in low-pass filter, you can
also select the “FLAT” setting and thus
allow all the frequencies to be sent to
the subwoofer.
You should adjust this setting to suit the
frequency range and capabilities of your
subwoofer. For further information,
please read the subwoofer’s documen-
tation.
