Sound is produced from analog
components, but not from digital
ones (DVD, LD, CD-ROM etc.).
• The digital input assignment is wrong. • Assign the digital inputs correctly (see Assigning the
digital inputs on page 83).
• The digital components aren't connected
properly.
• Make sure you have properly connected the digital
component to the corresponding input on the back of the
amplifier (see Connecting your equipment on page 12).
• The player is not compatible with the source
you're using, or the player settings are
incorrect.
• Choose a compatible source, or check the component’s
manual for the correct settings.
• The digital output level has been turned
down on a CD player or other component
equipped with digital output level adjustment
capability.
• Set the digital volume level of the player to full, or to the
neutral position.
• Analog input has been selected. • Select digital input (see Selecting the input signal type
on page 44).
When playing an LD the input
signal type is 2RF but there is
still no sound.
The LD is not a Dolby Digital compatible disc. • Set the input signal to AUTO (see Selecting the input
signal type on page 44). Also make sure your LD player is
hooked up with analog connections in addition to digital
and 2RF connections (see Connecting other video
sources on page 19).
No sound output from the
headphones.
The U-shaped connectors that connect the
POWER AMP IN terminals to the front
channel pre-outs are not connected.
• Reconnect the POWER AMP IN terminals to the front
channel pre-outs using the supplied U-shaped connectors
(see item 8 in Rear panel on page 12).

multichannel DVD-Audio or
SACD disc.
• DVD players do not output digital audio
when playing these kinds of discs.

connect your DVD player to this amplifier through the
multichannel analog inputs. See Connecting the
multichannel analog outputs on page 16 and also the
operating instructions that came with your DVD player.
No digital output when playing a
192/176.4 kHz sampling rate
DVD-Audio disc.

these sampling rates. Usually, players output
the audio from these discs at a downsampled
rate of 96/88.2 kHz or 48/44.1 kHz. Some discs
prohibit all digital output.
• This is not a malfunction. To enjoy fully these discs,
connect your DVD player to this amplifier through the
multichannel analog inputs. See Connecting the
