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
