Harman-Kardon AVR65 Home Theater System User Manual

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 minimum peak
level by
/4 to
/3. This prevents abruptly
loud transitions from causing distur-
bances without reducing the impact of
the digital source. The Night mode is
available only when AC-3 signals with
special data are being played.
To engage the Night mode, press the
Night buttonjon the remote and
note that the NIGHT indicator L 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
DATAmessage to be displayed in the
Main Information Display U or on-
screen display (Figure 8). This is normal
and does not indicate a problem with
either the AVR65 or the source machine.
The AVR65 will return to digital playback
as soon as the data is available when the
machine is in a standard play mode.

2. The AVR65 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 and HDTV sources, it is pos-
sible that some future digital sources
may not be compatible with the AVR65.
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 LV discs, connect
the AC-3/RF output of the player to the
demodulator, and connect the output
of the demodulator to the Coaxial or
Optical inputs °· on the rear panel
of the AVR65. DO NOT connect the
AC-3/RF output of a laser disc player
directly to the AVR65.
3. Note that not all digitally encoded
programs contain full 5.1 channel
audio. Consult the program guide that
accompanies the DVD or laser disc to
determine which type of audio has been
recorded on the disc. The AVR65 will
automatically sense the type of digital
surround encoding used and adjust to
accommodate it.
4. When a 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 digital program.
PCM Audio Playback
PCM (Pulse Code Modulation) is the
non-compressed digital audio system
used for compact discs and non-AC-3 or
DTS laser discs. The digital circuits in the
AVR65 are capable of high-quality digital-
to-analog decoding, and they may be
connected directly to the digital audio
output of your CD or LV player.
Connections should be made to the
Optical or Coaxial inputs °· on the
rear panel, using whichever input is not
occupied by a digital 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 Digital button
w ˆ and then using the
g on the remote or the Selector
buttons¸on the front panel until the
desired choice of either COAXIALor
OPTICAL, as it appears in the Main
Information Display U. Press the Set
button i ˜ to enter the desired choice.
When a PCM source is playing, the PCM
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.
Tuner Operation
The AVR65’s tuner is capable of tuning
AM, FM and FM Stereo broadcast stations.
Stations may be tuned manually, or they
may be stored as favorite station presets
and recalled from a 30-position memory.
