The 18S conguration menu parameters
and their options are described in the
following paragraphs:
• Input sensitivity: Adjusts the input
sensitivity to match the output level
of your pre-amplier or audio-
visual processor. Initially select the
0dB option. Only adjust the input
sensitivity if the subwoofer volume
adjustment doesn’t provide a
suitable range.
• Volume: Set to match the volume of
your main speakers so that bass at
your main listening position is neither
too prominent or too quiet.
• Presets: The 18S incorporates low
pass lter presets to match a range
of Dynaudio speaker models. If
your 18S is to be used in a system
with one of the Dynaudio models
listed, select it to congure the 18S
low pass lter appropriately. If your
subwoofer is to be used for the LFE
channel in a home theatre system
select the lter Bypass option.
• Parametric EQ: Provides three
bands of low frequency parametric
equalisation. Each band offers
frequency, gain and Q parameters.
Parametric is best used in
combination with low frequency
room acoustic analysis to identify
frequency response anomalies. The
equalisation is set to “at” by default.
• Auto standby: Select to specify
the delay time before the subwoofer
will switch to Standby mode when
unused. The auto standby feature
can also be switched off.
• Line Wake-up: Select to enable or
disable trigger input switch on.
• Left main speaker distance:
Select to specify the distance in
metres of the left channel monitor
from the listening position.
• Right main speaker distance:
Select to specify the distance in
metres of the right channel monitor
from the listening position.
Note
Setting the subwoofer volume is
important in terms of both overall
system balance and the demands
of different types of programme
material.
Note
If your Dynaudio speaker model
is not listed among the 18S
presets, or your 18S is to be
used with speakers from an
alternative manufacturer, select
the generic lter preset closest to
the speaker’s specied -6dB low
frequency cut-off.
