No sound from surround or 
center speakers.

• 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.

The 

PHASE CONTROL 

feature doesn’t seem to 
have an audible effect.

• 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).

Considerable noise in radio 
broadcasts.

• 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).

Broadcast stations cannot 
be selected automatically.

• Connect an outdoor antenna (refer to page 27).

Noise during playback of a 
cassette deck.

• Move the cassette deck away from your receiver, until the noise 
disappears.

Sound is produced from 
other components, but not 
from LD or DVD player.

• Set the 

SIGNAL SEL to HDMI, C1/O1/O2 (DIGITAL) or A (analog) 

according to the type of connections made (refer to page 41).
• Set the digital input settings correctly (refer to page 46).
• Make digital connections (refer to page 23) and set the 

SIGNAL SEL to 

C1/O1/O2 (DIGITAL) (refer to page 41).
• Refer to the instruction manual supplied with the DVD player.

No sound is output or a 
noise is output when 
software with DTS is played 
back.

• Set the digital volume level of the player to full, or to the neutral 
position.
• 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.
• Set the input signal type to 

C1/O1/O2 (DIGITAL) (see Choosing the 

input signal on page 41).

During a playback search, 
noise is output from a DTS 
compatible CD player.

• This is not a malfunction, but be sure to turn the volume down to 
prevent the output of loud noise from your speakers.

Everything seems to be set 
up correctly, but the 
playback sound is odd.

• Check that the positive/negative speaker terminals on the receiver are 
matched with the corresponding terminals on the speakers (see 
Connecting the speakers on page 18).
