Subwoofer (SW FREQ.) frequency
• For the subwoofer frequency at the speaker setting screen, set
the bass crossover frequency for playback from the subwoofer
• Select "80 Hz", "120 Hz", "150 Hz" or "180 Hz" (-6 dB for
each). Bass sound below these frequencies is played from the
subwoofer.
(This is set to "80 Hz" by factory default.)
Assignment of low frequencies
• In the Dolby Digital, Dolby Pro Logic H, DTS, and virtual surround
modes, the low frequency signals for channels whose speaker
settings are set to "Small" are assigned to the subwoofer The
low frequencies of channels set to "Large" are played from
those channels
(if set to "120 Hz", channels set to "Small" play sounds of 120
Hz and greater, while bass frequencies of under 120 Hz are
played from the subwoofer.)
• In surround modes other than the ones listed above, low
frequencies below the frequency set at the subwoofer frequency
setting are played from the subwoofer regardless of whether the
speakers are set to "Large" or "Small".
• Set the subwoofer frequency according to the low frequency
playback abilities of your speakers and subwoofer
Subwoofer mode
• The subwoofer mode setting is only valid when "LARGE" is set
for the front speakers and "YES" is set for the subwoofer in the
"SPEAKER CONFIGURATION" settings.
• When the "LFE+MAiN" playback mode is selected, the low
frequency signal range of channels set to "LARG E" are produced
simultaneously from those channels and the subwoofer channel.
In this playback mode, the low frequency range expand more
uniformly through the room, but depending on the size and shape
of the room, interference may result in a decrease of the actual
volume of the low frequency range.
• Selection of the "LFE " play mode will play the low frequency
signal range of the channel selected with "LARGE" from that
channel only. Therefore, the low frequency signal range that are
played from the subwoofer channel are only the low frequency
signal range of LFE (only during Dolby Digital or DTS signal
playback) and the channel specified as "SMALL" in the setup
menu.
• Select the play mode that provides bass reproduction with body.
• When the subwoofer is set to "YES", bass sound is output from
the subwoofer regardless of the subwoofer mode setting in
surround modes other than Dolby/DTS.
