SYMPTOM
A loud hissing noise is heard when you
play back a source encoded with the DTS.
A percussive noise is heard when you
begin playing back a source encoded with
the DTS.
No sound is heard when you play back a
source encoded with the DTS, even though
the “AUTO” or “DTS” input mode is
selected on this unit.
No sound is heard when you play back an
MD onto which you have recorded a
source encoded with the DTS.
No sound is heard when you play back a
DAT onto which you have recorded a
source encoded with the DTS.
No sound is heard when you play back a
source (CD etc.) even though the currently
selected input mode is “AUTO”.
CAUSE
The player which plays back the source is
not connected to a digital audio signal input
terminal of this unit.
The “ANALOG” input mode is selected on
this unit.
If the “AUTO” input mode is selected,
depending on some sources, there may be a
case that a noise is heard while this unit is
identifying the format of input signal.
The DTS decoder built into this unit does not
function because the player has a digital
volume control and it is set at a position
other than “maximum”, “neutral” or
“ineffective”.
A source encoded with the DTS cannot be
recorded onto an MD.
Depending on a DAT deck, a source
encoded with the DTS cannot be recorded
onto a DAT.
In the “AUTO” mode, the DTS-decoding
mode cannot be changed to the normal
(PCM) digital signal input mode
automatically.
REMEDY
The player must be connected to a digital
audio signal input terminal of this unit besides
analog audio signal terminal connections.
Select a proper input mode on this unit to turn
on the DTS decoder built into this unit.
Set the input mode of the currently selected
input source to “DTS”.
Set the player’s digital volume control at the
maximum, neutral or ineffective position.
Press the INPUT MODE button on the front
panel or the input selector button (for the
currently selected source) on the remote
control transmitter so that “PCM” appears on
the display.
When playing back a source encoded with the DTS:
Notes
It is necessary to use a DTS decoder to play back a source encoded with the DTS, so the player which plays back a source must
be connected to a digital audio input terminal of this unit in the way described in this manual. If this connection is not made or only
a D/A converter is used without using a DTS decoder, when you play back a source, only a loud hiss noise will be heard.
If you make a search (or skip etc.) operation while playing back a source encoded with the DTS, the “PCM” indicator lights up on
the display. This is because this unit automatically changes the DTS-decoding mode to the normal (PCM) digital signal input
mode to prevent a noise from being output.
A source encoded with the DTS cannot be recorded onto analog audio and video tapes, and also, an analog tape recorded with a
source encoded with the DTS cannot be played back.
The same result is obtained for MDs and DATs (depending on a DAT deck used for recording and/or playback).
