Preparations
SUB WOOFER ON/PLUS/OFF setting mode
Sets whether the SUB WOOFER is used or not. Also, when used you have the option to use the "PLUS"
setting.
• Initial setting is "ON".
memo
• Setting the front speaker size to "Small" in the SPEAKER setting mode automatically
locks the sub woofer in the "ON" position.
• Use the PLUS for extra bass. When you use PLUS you will get the bass sounds from the
sub woofer even if the front speakers are set to "Large".
Crossover frequency setting mode
Crossover frequency is the point where the receiver divides the high and low sounds (the frequencies) between
the speakers. Since most smaller speakers can't handle deep bass tones, this setting allows you to send those
sounds to the sub woofer (or speakers set to "Large" if you don't have a sub woofer) instead of the speakers
set to "Small" in your system. Choose the point at which you want the frequency routed to the sub woofer (or
"Large" speakers).
We recommend setting this to 200 Hz if smaller bookshelf-type speakers are used for your "Small" speakers.
• Initial setting is "100 Hz".
memo
• If all speakers (front, center, and surround) are set to "Large" in SPEAKER setting mode,
crossover frequency cannot be set because there are no "Small" speakers (*** appears
in the display).

LFE attenuator setting mode
Dolby Digital and DTS audio sources include ultra-low bass tones. Set the LFE attenuator as needed to prevent
the ultra-low bass tones from distorting the sound from the speakers.
• Initial setting is "0 dB".
