SUBWOOFER
The Subwoofer Menu allows turning the Subwoofer ON (default) or OFF.
If any speaker is set to SMALL then the subwoofer must be ON for best
results.
Parameter Possible Settings
SUB WOOFER ON , OFF
in2Bypass ON , OFF
XTRA BASS ON , OFF (for large front speakers)
SUBWOOFER IN 2-CHANNEL BYPASS MODE:
Two channel bypass mode is selected by the front panel button labeled
―2 CH. BYPASS‖ and applies to analog stereo (left and right only) input
signals. The signals are bypassing the Digital Signal Processor (DSP)
and are routed only through analog preamps and analog volume control
circuit. In this mode DSP can be completely disabled when the
―in2BYPASS‖ option is OFF, or it can be used to extract the bass
contents of the analog L and R input channels and output it through the
Subwoofer sockets. When ―in2BYPASS‖ option is ON then the cross-
over frequency used for bass extraction is the one set up in: SOURCE
SETUPCROSSOVER FcFRONT, while the Subwoofer Volume
Level correction is the one set up in: SOURCE SETUPSPEAKER
LEVELSUB .
XTRA BASS FEATURE:
If Subwoofer is present and the Front speakers are declared as Large
then bass contents will be streamed through the Front speakers while
only LFE will be reproduced through the Subwoofer. In this case, in order
to make the subwoofer reproduce bass from the Front speakers as well,
in addition to being reproduced by the Front speakers, Xtra Bass option
can be enabled. Xtra Bass option has no effect and is disabled when the
Front speakers are declared Small or when no subwoofer is present.
Xtra Bass option has no effect on LFE reproduction. To turn on the
XTRA BASS you must do the following:
Front speakers set to LARGE in SPEAKER SIZE
Turn ON the XTRA BASS in SOURCE
SETUPSUBWOOFERXTRA BASS In addition, the mixing
volume level of the bass contents can be adjusted by this parameter:
SOURCE SETUPSUBWOOFERLEVEL The adjustment range
is -20dB to 0dB. The LEVEL parameter applies only to Subwoofer in
Xtra Bass (on top of the normal Subwoofer Level correction from
SOURCE SETUPSPEAKER LEVEL). It is disabled and not
applied if Extra Bass is OFF.
You cannot use XTRA BASS if the front speakers are set to SMALL
