SUBWOOFER
NONE
If you do not connect a subwoofer,
select this. This activates the Dolby
Digital bass redirection circuitry and
outputs the LFE signals from the front
speakers as long as the front speaker
size is set to "LARGE."
YES
If you connect a subwoofer, select this
to output the LFE (low frequency
effect) channel from the subwoofer.
When you set the other speakers
settings to "SMALL," the subwoofer
makes up for the missing bass
frequencies of the speakers.
Notes
The cut off frequency for the subwoofer is fixed at
120 Hz.
If your speakers are too small to reproduce low bass
frequencies, please set all speaker settings to
"SMALL" and utilize a subwoofer for low
frequency sound.
Even if there are fewer than 6 speakers connected,
the player distributes the audio signal components to
the front speakers.

an equal distance from your listening position, set
the distance according to the closest speaker.
