Switching the input mode
This unit allows you to switch the input mode only for sources
that input two or more types of signals to this unit.
For CD, MD/TAPE 1, TV/DBS and
DVD/VCR 3 sources:
The following two input modes are provided.
AUTO:
This mode is automatically selected when you turn on the
power of this unit.
In this mode, input signal is automatically selected by the
following order of priority.
1. Digital signal encoded with the Dolby Digital (AC-3) or the
DTS, or Normal digital input signal (PCM)
2. Analog input signal (ANALOG)
* For CD, TV/DBS and DVD/VCR 3 sources, if digital signals
are input from both of the OPTICAL and COAXIAL
terminals, the digital signal from the OPTICAL terminal is
selected.
DTS:
In this mode, only digital input signal encoded with the DTS is
selected even though other signals are input at the same time.
ANALOG
In this mode, only analog input signal is selected even though
digital signal is input at the same time.
Select this mode when you want to use the analog input signal
instead of the digital input signal.
For LD sources:
The following five input modes are provided.
AUTO:
This mode is automatically selected when you turn on the
power to this unit.
In this mode, input signal is automatically selected by the
following order of priority.
1. Dolby Digital (AC-3) RF signal (DOLBY DIGITAL)
2. Digital signal encoded with the Dolby Digital (AC-3) or the
DTS, or Normal digital input signal (PCM)
3. Analog input signal (ANALOG)
AC-3 RF:
In this mode, only Dolby Digital (AC-3) RF signal is selected.
DTS:
In this mode, only digital input signal encoded with the DTS is
selected even though other signals are input at the same time.
DIGITAL:
In this mode, only digital input signal is selected even though
other types of signals are input at the same time.
ANALOG
In this mode, only analog input signal is selected even though
other types of signals are input at the same time.
Notes on input mode selection
For the TV/DBS and DVD/VCR 3 sources, the input mode
selected on the function "11. INPUT MODE" in the SET
MENU mode is selected when you turn on the power of this
unit.
To play back an LD source with the Dolby Digital (AC-3)
decoded, set the input mode to "AUTO" or "AC-3 RF".
When you want to enjoy a source which has normal 2-
channel signals with a Dolby Pro Logic Surround program,
select the ANALOG mode.
In the AUTO mode, there may be a case depending on
some LD players or DVD players that when you make a
search on a source encoded with the Dolby Digital (AC-3) or
the DTS during playback and then playback is restored,
sound output is interrupted for a moment because the digital
input signal is selected again.
For sources PHONO, TUNER, TAPE 2, VCR 1, VCR 2 and
V-AUX, the input mode cannot be changed because they
input analog signals only to this unit.
When the input source is changed to LD, CD, MD/TAPE 1,
TV/DBS or DVD/VCR 3, or the input mode is changed, the
currently selected input mode is shown on the display panel
and the monitor screen.
If changed to the AUTO mode, the type of selected input
signal is also shown as figured below.
* However, if those operations are made when the test tone is
output from this unit, the type of selected input signal will
not be shown. (Only "AUTO" will be displayed.)
Notes on playing back a source encoded with the DTS
When you play back an LD or CD source with the DTS
decoded (with the red "dts" indicator illuminated on the
display) in the AUTO mode, a noise may be heard just
after playback begins. To prevent such a noise, select
the DTS mode.
Be careful not to play back these sources in the
ANALOG mode. If they are played back in the ANALOG
mode, only a noise will be output from the speakers.
If you play back a CD or LD source encoded with the
DTS in the AUTO mode, this unit is locked in the DTS-
decoding mode automatically to prevent the generation
of noise possible in subsequent operations. In this state,
the red "dts" indicator flashes.
In this state, if you play back a CD or LD with normal
(PCM) digital signals, no sound will be heard. To play
back these sources normally, press the INPUT MODE
button on the front panel or the input selector key for the
currently selected source on the remote control
transmitter so that "PCM" appears on the display.
