This unit is equipped with a variety of input jacks. You
can select the type of input signals you wish to use.
Each time you turn on the unit power, the input mode is
set to the "INPUT 2 INPUT MODE" setting defined in
the set menu.
Press INPUT MODE repeatedly until the
desired input mode is shown on the front

AUTO: In this mode, the input signal is selected
automatically as follows:
1) Digital signal
2) Analog signal
DTS: In this mode, only digital input signals
encoded with DTS are selected, even if the
unit is receiving another signal
simultaneously.
ANALOG: In this mode, only analog input signals are
selected, even the unit is receiving digital
signals at the same time.
Notes
• When AUTO is selected, this unit automatically determines
the type of signal. If it detects a Dolby Digital or DTS signal,
the decoder automatically switches to the appropriate setting.
• When playing a disc encoded with Dolby Digital or DTS on
some LD or DVD players, there is a delay in sound output for
a moment when playback resumes after a search, because the
unit must select the digital signal again.
• When playing a LD source that has not been digitally
recorded, the unit may not output any sound for some LD
players. In this case, set the input mode to ANALOG.

I Notes on digital signals
The digital input jacks of this unit can handle 96 kHz
sampling digital signals. Note the following when a
digital signal with a sampling frequency greater than 48
kHz is input to this unit:
• You cannot use any DSP programs.
• The unit will output sound as 2-channel stereo from the
main left and right speakers only. Therefore, you
cannot adjust the level of the effect speakers while
listening to such a source.
I Notes on playing DTS-CD/LDs
• If the digital output data of the player has been
processed in any way, the unit may not be able to
perform DTS decoding even if there is a digital
connection between this unit and the player.
• If you play a source encoded with a DTS signal and set
the input mode to ANALOG, the unit may reproduce
the noise of an unprocessed DTS signal. In this case,
connect the source to a digital input jack on this unit
and set the input mode to AUTO or DTS.
• If you switch the input mode to ANALOG while
playing a source encoded with a DTS signal, the unit
does not output any sound.
R • If you play a source encoded with a DTS signal with
the input mode set to AUTO;
– The unit automatically switches to the DTS-
decoding mode (The "t" indicator lights up)
after detecting the DTS signal. When playback of
the DTS source is completed, the "t" indicator
may flash. While this indicator is flashing, the unit
can only reproduce DTS source. If you want to play
a normal PCM source immediately, change the input
mode back to AUTO.
– When the input mode is set to AUTO and a search
or skip operation is performed during playback of a
DTS source, the "t" indicator may flash. If this
state continues for longer than 30 seconds, the unit
will automatically switch from "DTS-decoding"
mode to PCM digital signal input mode. The "t"
indicator will turn off.
