Remedy
• If the subwoofer has a volume knob, make sure it's turned up.
• The Dolby Digital or DTS source you are listening to may not have an
LFE channel.
• Switch the subwoofer setting in Speaker Setting on page 43 to YES or
PLUS.
• Switch the LFE ATT (LFE Attenuate) on page 40 to LFEATT 0 or LFEATT 5.
• Connect the speakers properly (refer to page 18).
• Refer to Speaker Setting on page 43 to check the speaker settings.
• Refer to Channel Level on page 45 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).
• Make sure the speaker distance setting is correct for all speakers (see
Speaker Distance on page 46).
• Connect the antenna (page 27) and adjust the position for best
reception.
• Route any loose cables away from the antenna terminals and wires.
• Fully extend the FM wire antenna, position for best reception, and
secure to a wall (or connect an outdoor FM antenna).
• Connect an additional internal or external AM antenna (page 27).
• Turn off equipment causing interference or move it away from the
receiver (or move antennas farther away from equipment causing noise).
• Connect an outdoor antenna (refer to page 27).
• Move the cassette deck away from your receiver, until the noise
disappears.
• Make sure the player's settings are correct and/or the DTS signal out is
on. Refer to the instruction manual supplied with the DVD player.
• See Automatically setting up for surround sound (MCACC) on page 29 to
set up your system again using MCACC (this will automatically
compensate for a delay in the subwoofer output).
• Low-frequency noise could have been caused by an air conditioner or
motor. Switch off all appliances in the room and rerun the Auto MCACC
Setup.
