• Parameters
Large...... Select this when using speakers that can fully reproduce low sounds of below 80 Hz.
Small...... Select this when using speakers that cannot reproduce low sounds of below 80 Hz with sufficient
volume. When this setting is selected, low frequencies of below 80 Hz are assigned to the
subwoofer.
None...... Select this when no speakers are installed.
Yes/No.... Select "Yes" when a subwoofer is installed, "No" when it's not installed.
NOTE:
Select "Large" or "Small" not according to the physical size of the speaker, but according to the bass
reproduction capacity at 80 Hz. If you cannot determine the best setting, try comparing the sound when set to
"Small" and when set to "Large", at a level that will not damage the speakers.
Caution:
In case the subwoofer is not used, be sure to set "Subwoofer = No", or the bass sound of front channel is
divided to subwoofer channel and not reproduced in some mode.

NOTES:
— Assignment of low frequency signal range —
• The signals produced from the subwoofer channel are LFE signals (during playback of Dolby Digital or DTS
signals) and the low frequency signal range of channels set to "SMALL" in the setup. The low frequency
signal range of channels set to "LARGE" are produced from those channels.
— Crossover Frequency —
• When "Subwoofer" is set to "Yes" at the "Speaker Configuration Setting", set the frequency (Hz) below
which the bass sound of the various speakers is to be output from the subwoofer (the crossover
frequency).
• For speakers set to "Small", sound with a frequency below the crossover frequency is cut, and the cut bass
sound is output from the subwoofer instead.
NOTE: For ordinary speaker systems, we recommend setting the crossover frequency to 80 Hz. When
using small speakers, however, setting the crossover frequency to a high frequency may improve
frequency response for frequencies near the crossover frequency.
— 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 (see pages 10, 11).
If "SMALL" is set for the front speakers or "NO" is set for the subwoofer, the subwoofer mode setting
does not affect playback of low frequency signal range.
• When the "+MAIN" playback mode is selected, the low frequency signal range of channels set to
"LARGE" 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.
• When the "NORM" playback mode is selected, the low frequency signal range of channels set to "LARGE"
are only produced from those channels. In this playback mode there tends to be little interference of the
low frequency range in the room.
• Try playing the music or movie source and select the playback mode providing the stronger low frequency
range sound.
