• To select the parameter
• 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.
If the subwoofer has sufficient low frequency playback capacity, good sound can be achieved even when
“Small” is set for the front, center and surround speakers.
For the majority of speaker system configurations, using the Small setting for all five main speakers and
Subwooofer On with a connected subwoofer will yield the best results.
