LFE channel.
• Switch the subwoofer setting in Speaker Setting on page 45 to YES or
PLUS.

• Connect the speakers properly (refer to page 19).
• Refer to Speaker Setting on page 45 to check the speaker settings.
• Refer to Channel Level on page 47 to check the speaker levels.
• If applicable, check that the lowpass filter switch on your subwoofer is
off, or the lowpass cutoff is set to the highest frequency setting. If there is
a PHASE setting on your subwoofer, set it to 0º (or depending on the
subwoofer, the setting where you think it has the best overall effect on the
sound).

Speaker Distance on page 48).

reception.

receiver (or move antennas farther away from equipment causing noise).

disappears.
