Input mode selection function
Different input modes can be selected for the different
input sources. The selected input modes for the
separate input sources are stored in the memory.
q AUTO (All auto mode)
In this mode, the types of signals being input to the
digital and analog input jacks for the selected input
source are detected and the program in the AVR-
1803’s surround decoder is selected automatically
upon playback. This mode can be selected for all
input sources other than PHONO and TUNER.
The presence or absence of digital signals is
detected, the signals input to the digital input jacks
are identified and decoding and playback are
performed automatically in DTS, Dolby Digital or
PCM (2 channel stereo) format. If no digital signal
is being input, the analog input jacks are selected.
Use this mode to play Dolby Digital signals.
w PCM (exclusive PCM signal playback mode)
Decoding and playback are only performed when
PCM signals are being input.
Note that noise may be generated when using this
mode to play signals other than PCM signals.
e DTS (exclusive DTS signal playback mode)
Decoding and playback are only performed when
DTS signals are being input.
r ANALOG (exclusive analog audio signal playback
mode)
The signals input to the analog input jacks are
decoded and played.
t EXT. IN (external decoder input jack selection mode)
The signals being input to the external decoder
input jacks are played without passing through the
surround circuitry.
NOTE:
• Note that noise will be output when CDs or LDs
recorded in DTS format are played in the “PCM”
(exclusive PCM signal playback) or “ANALOG”
(exclusive analog audio signal playback) mode.
Select the AUTO or DTS (exclusive DTS signal
playback) mode when playing signals recorded in
DTS.
Notes on playing a source encoded with DTS
• Noise may be generated at the beginning of
playback and while searching during DTS
playback in the AUTO mode. If so, play in the
DTS mode.
•
In some rare cases the noise may be generated
when you preform the operation to stop
playback of a DTS-CD or DTS-LD.
To select the input source when
REC OUT is selected, press the
SOURCE button then operate
the input function selector.

(Main unit) (Remote control unit)
To select the surround mode
while adjusting the surround
parameters, channel volume or
tone control, press the surround
mode button then operate the
selector.
(Main unit)
Start playback on the selected component.
•
For operating instructions, refer to the component’s
manual.

Adjust the volume.
5
(Main unit) (Remote control unit)
The volume level is
displayed on the master
volume level display.
The volume can be adjusted within the range
of –70 to 0 to 18 dB, in steps of 1 dB. However,
when the channel level is set as described on
page 19, if the volume for any channel is set
at +1 dB or greater, the volume cannot be
adjusted up to 18 dB. (In this case the
maximum volume is adjusted to “18 dB —
(Maximum value of channel level)”.)
Input mode when playing DTS sources
• Noise will be output if DTS-compatible CDs or LDs
are played in the “ANALOG” or “PCM” mode.
When playing DTS-compatible sources, be sure to
connect the source component to the digital input
jacks (OPTICAL/COAXIAL) and set the input mode
to “DTS”.
