Introduction and Safety Information
Congratulations!Your purchase of an
ADP303 places you in the vanguard of
home theater listeners. The ADP303s
advanced circuitry decodes the Dolby
Digital (AC-3) signals from standard
laser discs, the latest DVD players and
other future digital audio sources to
deliver six separate, discrete audio
channels. The realism of AC-3 finally
allows you to hear motion picture
soundtracks and music videos with the
digital clarity of the best first run movie
theater.
While complex systems are hard at work
within the ADP303 to decode the digital
audio, hook-up and operation are
simple. However, to obtain the
maximum enjoyment from your new
decoder we urge you to take a few
minutes to read through this manual.
This will ensure that connections to
source playback units, receivers or
amplifiers and other external devices are
made properly. In addition, a few
minutes spent learning the functions of
the various controls will enable you to
take advantage of all the processing
power the ADP303 is able to deliver.
If you have any questions about this
product, its installation or operation,
please contact the retailer or custom
installer who sold you the product. They
are your best source of local information. IMPORTANT SAFETY
INFORMATION
Verify Line Voltage Before Use
Your ADP303 has been designed for use
with 230 volt AC current. Connection to
a line voltage other than that for which it
is intended can create a safety and fire
hazard, and may damage the decoder.
If you have any questions about the
voltage requirements for your specific
model, or about the line voltage in your
area, contact your selling dealer before
plugging the unit into a wall outlet.
Do Not Use Extension Cords
To avoid safety hazards, use only the
power cord supplied with your unit. If a
replacement cord is used, make certain
that it is of similar gauge. We do not
recommend that extension cords be used
with this product. As with all electrical
devices, do not run power cords under
rugs or carpets or place heavy objects on
them. Damaged power cords should be
replaced immediately with cords meeting
factory specifications.
Handle the AC Power Cord Gently
When disconnecting the power cord from
an AC outlet, always pull the plug, never
pull the cord. If you do not intend to use
the decoder for any considerable length
of time, disconnect the plug from the AC
outlet.
Do Not Open The Cabinet
There are no user serviceable
components inside this product. Opening
the cabinet may present a shock hazard,
and any modification to the product will
void your warranty. If water or any metal
object such as a paper clip, wire or a
staple accidentally falls inside the unit,
disconnect it from the AC power source
immediately, and consult an authorized
service station.
Installation Location
- To assure proper operation, and to
avoid the potential for safety hazards,
place the unit on a firm and levelsurface. When placing the unit on a
shelf, be certain that the shelf and any
mounting hardware can support the
weight of the product.
- Make certain that proper space is
provided both above and below the unit
for ventilation. If this product will be
installed in a cabinet or other enclosed
area, make certain that there is sufficient
air movement within the cabinet.
- Do not place the unit directly on a
carpeted surface.
- Avoid installation in extremely hot or
cold locations, or an area that is exposed
to direct sunlight or heating equipment.
- Avoid moist or humid locations.
- Do not obstruct the ventilation slots on
the top of the unit, or place objects
directly over them.
Cleaning
When the unit gets dirty, wipe it with a
clean, soft dry cloth. If necessary, wipe it
with a soft cloth dampened with mild
soapy water, then a fresh cloth with clean
water. Wipe dry immediately with a dry
cloth. NEVER use benzene, thinner,
alcohol or any other volatile cleaning
agent. Do not use abrasive cleaners, as
they may damage the finish of metal
parts. Avoid spraying insecticide near the
unit.
Moving The Unit
Before moving the unit, be certain to
disconnect any interconnection cords
with other components, and make
certain that you disconnect the unit from
the AC outlet.

Introduction and Safety Information
UNPACKING & INSTALLATION
The carton and shipping materials used
to protect your new ADP303 during
shipment were specially designed to
cushion it from shock and vibration. We
suggest that you save the carton and
packing materials for use in shipping if
you move or should the unit ever need
repair.
To minimize the size of the carton in
storage, you may wish to flatten it. This
is done by carefully slitting the tape
seams on the bottom and collapsing the
carton down to a more two dimensional
appearance. Other cardboard inserts may
be stored in the same manner. Packing
materials that cannot be collapsed
should be saved along with the carton in
a plastic bag.
If you do not wish to save the packaging
materials, please note that the carton
and other sections of the shipping
protection are recyclable. Please respect
the environment and discard those
materials at a local recycling center.
When positioning your ADP303 in its
final location, make certain that any
shelf or stand is capable of supporting its
weight, and that there is adequate
ventilation on all sides, as well as on the
top and bottom. Do not place CDs,
record jackets, owners manuals, or other
paper on top of, or beneath the unit. This
will block air flow and create a potential
fire hazard. If the unit is to be enclosed
in a cabinet or rack, make certain that
there is adequate air circulation, with a
means provided for hot air to exit, and
for cool air to be brought in.
WHAT IS DOLBY DIGITAL?
Dolby Digital, or AC-3 as it is often
referred to, is a totally new generation of
multi-channel digital audio technology.
Using advanced circuit designs and
specially developed compression
techniques, AC-3 delivers significant
advances over previous multi-channel
systems: it delivers noise free, wide
bandwidth sound and it includes six
separate audio channels.
AC-3 evolves from Dolby Laboratories
constant research into new ways to
deliver high quality audio for theatrical
motion picture presentation and
transmission via satellite and
telecommunications links. In fact, the
AC in AC-3 stands for Audio Coding,
the technique used in Dolby Digital for
data compression.
The ADP303 digital demodulator/
decoder brings that same 5.1 channel
high quality sound that accompanies
many major motion pictures into your
home when used with a compatible laser
disc player, as well as from future Dolby
Digital sources such as DSS, Digital Video
Disc (DVD) and High Definition
Television (HDTV).
For todays Laser Disc systems the digital
audio signal is recorded as a modulated
RF signal, similar to the signals used for
FM and TV broadcasts. That is why
connections to a laser disc are made
through an RF input. New technology
products such as DVD will feature direct
data outputs, and they are connected
directly to the ADP303s decoding
circuitry, without the need for the
demodulator stage. Both Coaxial and
Optical data inputs are available.
Traditional stereo recordings consist of
two channels, left and right, even though
the original intent of sound engineers
was to have a multitude of channels
available to present a realistic audio
soundfield. Unfortunately, early
recording techniques for vinyl recordsand optical movie soundtracks were
limited to two channels. Dolby Surround
was the technology that broke the two
channel barrier, by placing two
additional channels within the left and
right signals.
Those two additional channels presented
center channel information, primarily
for movie dialog, and a single, mono
rear channel for effects. The
combination of these two channels with
the existing left and right signals and low
frequency information derived via filters
or an electronic crossover gave home
theater and musical presentations a
realism never before possible.
Dolby Digital takes surround sound to a
new and even higher level. The use of
digital recording techniques enables all
surround channels to be full range,
where the surround channel in older
matrix surround systems is frequency
limited. Dolby Digital also delivers six
separate, discrete channels, including
highly defined left and right surround
channels. With two rear channels instead
of the single, mono channel of Dolby
ProLogic there is a greater feeling of
reality and presence for surround effects
such as flyovers of planes and
spaceships. Discrete digital sound also
enables complete separation between the
left front, center, right front, right rear
and left rear channels. The matrix
system used in conventional surround
recordings was often plagued with cross
talk between the channels. That is now
gone with Dolby Digital.
