abled. If no digital signal is present, the ana-
log inputs for that source are selected. This
auto-sensing is the preferred configuration for
digital source inputs such as DVD players.
When an ANALOG input is assigned, the unit
will not access a digital signal, even though
one may be available at the digital input.
By default, the source input buttons are fac-
tory configured to select the following inputs:
CD: Analog input
Tuner: Analog input
Tape: Analog input
Video 1: Digital Coaxial 1
Video 2: Digital Coaxial 2
Video 3: Digital Coaxial 3
Video 4: Digital Optical 1
Video 5: Digital Optical 2
Each source input should be configured us-
ing the ON-SCREEN DISPLAY menu system to
use the desired input type (analog or digital
auto-sensing). See the INPUT MENU section
for configuration instructions.
: In addition to selecting analog or digital
NOTE
signals, the configuration options also permit
custom labeling and selection of a default sur-
round mode for each of the inputs.
The input source buttons can also be used with
the REC button to select an analog input source
signal to be available at the outputs for record-
ing. Additionally, the input source buttons can
be used with the ZONE button to select an
analog input source for ZONE 2.

Overview of
Surround Formats
To get the best performance from your
RSP-1068, it helps to understand the many
surround sound formats available today, to
know which decoding process to use for a
particular recording, and how to select it. This
section provides basic background informa-
tion about surround sound formats. The follow-
ing sections provide detailed operating instruc-
tions for automatic and manual selection of
surround modes.

Dolby Surround

Dolby Pro Logic II

The most widely available surround sound
format for consumer audio/video is Dolby
Surround ® , available on nearly all commer-
cial VHS tapes, many television broadcasts,
and most DVDs. Dolby Surround is the con-
sumer version of the analog Dolby Stereo system
first introduced in the film industry in 1972. It
is a matrix-encoding system that records front
left, front center, front right, and a mono sur-
round channel into a 2-channel stereo record-
ing. During playback, a Dolby Pro Logic
Pro Logic II decoder extracts each channel and
distributes it to the appropriate speakers.
The original Dolby Pro Logic decoder deliv-
ered a mono signal with reduced high-fre-
quency content to the surround speakers. A
more advanced decoder in the RSP-1068,
Dolby Pro Logic II, increases the separation
and frequency response of the surround chan-
nels for significantly improved performance
with Dolby Surround encoded recordings.
Dolby Pro Logic II decoding should be used
for any analog recording labeled "Dolby Sur-
round" or any Dolby Digital 2.0 soundtrack.
Dolby Pro Logic II does a superb job deriving
surround sound from conventional 2-channel
stereo recordings, using phase relationships
to extract front, right, center, and surround chan-
nels. A "music mode" makes Pro Logic II an
excellent choice for audio CDs.

Dolby Digital

In 1992, a digital recording system, called
Dolby Digital, was first used in the film indus-
try. Dolby Digital is a recording/playback sys-
tem that uses compression techniques to store
large amounts of audio data efficiently, much
like the JPEG format stores large photographs
in small files on a computer. Because it is
capable of performance beyond that of au-
dio CDs and can tailor its output for a wide
ranges of system configurations, Dolby Digi-
tal is the standard audio format for DVDs and
for digital television broadcasting in the United
States.
The Dolby Digital system can be used to record
up to six discrete audio channels, but can also
be used for fewer. For example, a Dolby Digital
2.0 soundtrack is a digital 2-channel record-
ing of a matrix encoded Dolby Surround
soundtrack.. To play a Dolby Digital 2.0 re-
cording, use Dolby Pro Logic II decoding as
previously described.
