Operation

26

3/1:

This message indicates the AC-3

system is decoding a standard Dolby Pro
Logic signal with left, center and right
front channels and a signal mono
surround channel.

2/0:

This message indicates that the

AC-3 system is decoding a traditional
two-channel stereo signal and that no
center, surround or LFE signals are
present.

1+1:

This is a monaural signal that

plays the same information in both the
left front and right front speakers. There
is no sound sent to the center or
surround speakers.

1/0:

This is a monaural signal that

plays through the center channel
speaker only. There is no sound at the
front left/right or surround speakers.

Night Mode
A special feature of Dolby Digital is the
Night mode, which enables AC-3 input
sources to be played back with their full
range while reducing the maximum peak
level by 

1/4

to 

1/3

. This prevents abruptly

loud transitions from causing disturbances
without reducing the impact of the digital
source in the remaining level range. The
Night mode is available only when AC-3
signals are being played.

To engage the Night mode, press the

button

k

on the remote and note

that the 

indicator 

K

will

illuminate in the Information Display.

1. When the digital playback unit is in a
pause, fast forward or chapter search mode
the digital audio data may momentarily
stop, causing a 

NO DATA

message to be

displayed. This is normal and does not
indicate a problem with either the
AVR35RDS or the source machine. The
AVR35RDS will return to Dolby Digital/AC-
3 playback as soon as the data is available
when the machine is in a standard play
mode.

2. The AVR35RDS will decode digital audio
sources with a sampling frequency of
32kHz, 44.1kHz and 48kHz. Although this
will enable it to decode virtually all DVD
movies, CD and MD sources, it is possible
that some future digital sources may not be
compatible with the AVR35RDS.

NOTE: In order to play the Dolby Digital
signals that are recorded on laser discs,
you must have both a laser disc player with
an RF output, and an optional, outboard
RF-to-data demodulator. To listen to Dolby
Digital LD discs, connect the AC-3/RF
output of the player to the demodulator,
and connect the output of the demodulator
to the 

or 

inputs 

fl ‡

on the rear panel of the AVR35RDS. DO
NOT connect the AC-3/RF output of a laser
disc player directly to the AVR35RDS.

3. Note that not all programs recorded in
Dolby Digital contain full 5.1 channel audio.
Consult the program guide that accompa-
nies the DVD or laser disc to determine
which type of audio has been recorded on
the disc. The AVR35RDS will automatically
sense the type of digital surround encoding
used on an AC-3 program source and adjust
to accommodate it.

4. When a Dolby Digital source is playing,
you may not select any of the analog
surround modes.

5. It is not possible to record the output of
a Dolby Digital program (recording its
analog two channel audio track see 
page 29).

PCM Audio Playback
PCM (Pulse Code Modulation) is the non-
compressed digital audio system used for
compact discs, Mini discs (MD) and non-
AC-3 laser discs. The digital circuits in the
AVR35RDS are capable of high-quality
digital-to-analog decoding, and they may
be connected directly to the digital audio
output of your CD, MD or LD player.

Connections should be made to the 

or 

inputs

fl ‡

on the rear panel, using whichever

input is not occupied by an AC-3 source
such as a DVD player.

To listen to a PCM digital source, first select
the input for the desired source (e.g., CD).
Next press the 

button 

y ˆ

and

then using the 

⁄

¤

buttons 

h

on the

remote or the

buttons

¸

on the

front panel until the desired choice of either

COAXIAL

or 

OPTICAL

, as it appears

in the 

V

.

Press the 

button 

j ˜

to enter the

desired choice.

When a PCM source is playing, the 

indicator 

I

will light, and the Main

Information Display will show the input
source and the digital type. During PCM
playback you may select any surround
mode except Dolby Digital.
