Other audio problems

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).

No sound is output or a noise is

output when Dolby Digital/DTS

software is played back.

• A DVD player not compatible with Dolby

Digital/DTS is being used.

• Make sure your DVD player is compatible with Dolby

Digital/DTS.

• The settings on the DVD player are incorrect

and/or the DTS signal output is turned off.

• 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.

• The digital output level is turned down on a

CD player or other component equipped with

digital output level adjustment capability. (The

DTS signal has been altered by the player, and

cannot be read.)

• Set the digital volume level of the player to full, or to the

neutral position.

No digital output from the DVD

player when playing a

multichannel DVD-Audio or

SACD disc.

• DVD players do not output digital audio

when playing these kinds of discs.

• To enjoy fully multichannel DVD-Audio and SACD 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.

• DVD players do not output digital audio at

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

multichannel analog outputs on page 16 and also the

operating instructions that came with your DVD player.

During playback of a Dolby

Surround EX / DTS ES

soundtrack, the LS, S and RS

indicators light but there is no

surround back channel sound.

• The listening mode is not set correctly. • Set the surround back channel to SB CH AUTO (see

Using the surround back channel on page 46).

Symptom Cause Remedy

Noise is output when scanning a

DTS CD.

• The scan function performed by the player

slightly alters the digital information, making

it unreadable.

• This is not a malfunction, but be sure to turn the volume

down to prevent the output of loud noise from your

speakers.

When playing a 96 kHz/24bit disc

the sound is too loud.

• Different discs have different recording

levels so some may be louder than others.

• Turn the volume down.

When playing a DTS format LD

there is audible noise on the

soundtrack.

• The input signal type is set to ANALOG.• Set the input signal type to DIGITAL (see Selecting the

input signal type on page 44)
