Broadcast stations cannot be
selected automatically, or
there is considerable noise in
radio broadcasts.

For FM broadcasts

• Fully extend the FM wire antenna, adjust the position for best reception and secure to a wall, etc.

• Use an outdoor antenna for better reception (see page 28).

For AM broadcasts

• Adjust the position and direction of the AM antenna.

• Use an outdoor antenna for better reception (see page 28).

• Noise may be caused by interference from other equipment, such as a fluorescent light, motor,
etc. Switch off or move the other equipment, or move the AM antenna.

A multichannel DVD source
appears to be downmixed to 2
channels during playback.

• Make sure that the multichannel analog inputs are selected (see

Selecting the multichannel analog

inputs on page 61).

Noise is output when scanning
a DTS CD.

• This is not a malfunction of the receiver. The scan function of your player alters the digital
information, making it unreadable, resulting in noise being output. Lower the volume when
scanning.

When playing a DTS format LD
there is audible noise on the
soundtrack.

• Make sure that the input signal type is set to

DIGITAL (see Choosing the input signal on page 38).

Can’t record audio.

• You can only make a digital recording from a digital source, and an analog recording from an
analog source.

• For digital sources, make sure that what you’re recording isn’t copy protected.

• Check that the

OUT jacks are properly connected to the recorders input jacks (see Connecting

analog audio sources on page 24).

Subwoofer output is very low.

• To route more signal to the subwoofer, set it to

PLUS or set the front speakers to SMALL (see

Speaker Setting on page 57).

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

• The speakers may be out of phase. 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 25).

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 59).

Noise or hum can be heard
even when there is no sound
being input.

• Check that personal computers or other digital components connected to the same power source
are not causing interference.

There seems to be a time lag
between the speakers and the
output of the subwoofer.

• See

Automatically setting up for surround sound (MCACC & Full Band Phase Control) on page 9 to

set up your system again using MCACC (this will automatically compensate for a delay in the
subwoofer output).

Can’t use the SR+ features.

• Make sure that

HDMI Control is set to OFF (see Setting the HDMI Control mode on page 88).

The maximum volume
available (shown in the front
panel display) is lower than the
+12dB maximum.

• This is not a malfunction. If the levels in

Channel Level on page 58 have been adjusted, the

maximum volume will change accordingly.
