Subwoofer:
In this menu point you set whether a subwoofer is
present in your loudspeaker system. Select one of the
following settings:
Bass-manager recommended setting for sub-
woofer / satellite systems.
If a sub-woofer is present. The signals of the
bass effect channel (LFE), and all other low
frequency bass signals (below the set
transition frequency) which are not reproduced
by the full-range loudspeakers, are passed to
the sub-woofer channel. In this mode it may
occur that the sub-woofer has no signal to
reproduce in some surround modes or with
multi-channel input signals which lack an LFE
channel.
If the bass manager is in use, the low-pass
filter on the sub-woofer should be switched off,
as the bass manager carries out the filtering.
Permanent recommended setting for full-range
loudspeakers and sub-woofer.
If a sub-woofer is present and you wish it to
operate constantly. In addition to bass
management the signals of all channels are
mixed together and reproduced by the sub-
woofer.
For constant sub-woofer operation the low-
pass filter on the sub-woofer must be switched
on and the transition frequency on the sub-
woofer set in such a way that the sub-woofer
only reproduces signals below the bottom
transition frequency of the main loudspeakers
(generally 30 - 40 Hz).
none if this setting is selected, at least the main
loudspeakers must be full-range types.
If no sub-woofer is present. The signals of the
bass effect channel (LFE) and all other low
frequency bass signals (below the set
transition frequency) are reproduced by the
main loudspeakers.
Note:
Provided that you have switched on the subwoofer in
the 'Speaker Setup', then you can adjust its level in the
'Main Menu' within the range -10 (dB) to +10 (dB), so
that the volume of the subwoofer matches the volume of
the other channels.
Satellite high pass:
Here the lower transition frequency for satellite speakers
can be selected. The bass range below the frequency set
here (for all loudspeakers whose size is set as 'Satellite')
is mixed by the bass manager onto other suitable
loudspeakers and the sub-woofer.
The following values (Hz) can be set:
50 60 70 80 90 100 120 150 180
