• SIGNAL SELECT is set incorrectly.
• The digital inputs are assigned
incorrectly, or not at all.
• The digital components aren't connected
properly.
• The player is not compatible with the
source you're using, or the player settings
are incorrect.
• The MULTI CH IN mode has been
selected.
• The digital output level has been turned
down on a CD player or other component
equipped with digital output level
adjustment capability.
• Settings route signal away from
subwoofer.
• That speaker is set to NO.
• The source is coming from something
other than the MULTI CH IN jacks (for
example, digital PCM output, etc.)
• Incorrect frequency.
• The antenna is not connected.
• Digital cables are near the antenna
terminals and wires.
• The antenna is poorly positioned.
• Interference caused by other equipment
(fluorescent lamp, motor, etc.).
• Weak radio signals.
• There is electrical interference from
another component or appliance.
• The search function performed by the
player interferes with the reading of digital
information.
• The SIGNAL SELECT is on ANALOG.
• You are trying to make an analog
recording from a digital signal, or a digital
recording of an analog source.
• The digital source is copy protected.
• The jacks for recording have not been
connected properly.
• Set SIGNAL SELECT to AUTO or
according to the type of connections made
(see page 45).
• Set the digital input settings correctly
(see pages 12, 23, and especially 91).
• Check all connections.
• Choose a compatible source, or check
the player's manual for the correct settings.
• Choose one of the listening modes (see
pages 46–48). The MULTI CH IN switches

antenna terminals and wires.
• Adjust the direction and position for best
reception.
• Turn off the equipment causing the noise
or move it away from the receiver.
• Place the antenna farther away from the
equipment causing the noise.
• Connect an outdoor AM or FM antenna
(see page 24).
• Check that personal computers or other
digital components connected to the same
power source are not causing interference.
• This is not a malfunction, but be sure to
turn the volume down to prevent the output
of loud noise from your speakers.
• Set the SIGNAL SELECT to DIGITAL (see
page 45).
• You can only record analog to analog, or
digital to digital. Make sure the playback
and recording components are hooked up
with the same kind of connections.

been copy protected.
• Check connections (see pages 20 & 22).
