INSTALLATION
The ADP303 delivers optimal perfor-
mance when it is used with the Harman
Kardon AVR80 or AVI250 although it is
also compatible with many other home
theater system configurations. Please
follow the instructions in this section
that describe the equipment and speaker
choices that most closely resemble that of
your own system. Depending on the
equipment in use, some of the switches
and settings may require adjustment,
while in other cases they may be left in
their factory preset positions.
Depending on the specific equipment in
your home theater setup, the ADP303 can
be connected in one of three configura-
tion options:
• Direct connection to A/V products such
as the Harman Kardon AVR80 or AVI250
that feature a SIX CHANNEL DIRECT
INPUT.
• Connection between an existing A/V
surround processor/pre-amp and your
power amplifier(s) and subwoofer (for
owners of separates-based home theater
systems).
• Connection to the PRE-OUT/MAIN-IN
jacks on the rear panel of your A/V
receiver, provided that it is equipped
with 5 pre-out/main-in jack pairs and a
subwoofer output jack.
SPEAKER SELECTION
The home theater system you already
have installed should work with the
ADP303 provided that there are left,
center and right front speakers, left and
right rear/surround speakers and a
subwoofer. For best results we
recommend that the front speakers be of
the same type, with identical or similar
driver units. This will deliver smooth
pans across the front sound stage as the
action moves from side to side.

Rear channel speakers need not be
identical to the front channel speakers,
but they should be of high quality. One
of the benefits of Dolby Digital AC-3 is
that the surround channels are full
range, while they were frequency limited
in earlier ProLogic type systems.
Bass effects are also an important part of
home theater. For optimal enjoyment a
subwoofer should be used as it is
optimized for low frequency
reproduction. If you have large full range
front speakers, however, they may be
used in place of a subwoofer with proper
setting of the rear panel switches.
For the best advice on speaker selection
consult your Harman Kardon dealer.
SPEAKER MODE SETTINGS
Since the ADP303 may be used with a
wide variety of speaker types, it is
important that you adjust the rear panel
speaker mode switches before use. Setting
these switches will tell the ADP303 what
type of speakers you are using so that the
audio outputs will be directed to the
proper speaker.
In general, a "Large" speaker is defined
as a traditional full range speaker that
includes a woofer or some prepackaged
"satellite/subwoofer" systems and is
capable of reproducing sounds below 100
Hz. For the purposes of this product, a
"Small" speaker is one that is not
capable of delivering sounds significantly
below 100 Hz. (Most "satellite" type
speakers fall into this category.) Before
setting the switches make note of the type
of front, center and rear speakers that
will be used. For further clarification of
your speakers' type consult the speaker
owner's manual and look on the
"specifications" page to find the
frequency range.
When you have the information on your
speakers, set the four switches as follows:
1) Front Speaker Mode
This switch determines the frequency
range of the front left/right speakers.
Select Large or Small depending on the
type of speaker you will be using. The
factory default setting is "Small".
Large: Set the switch to this position if
you are using full range speakers that are
capable of reproducing sounds below 100
Hz. In this position, the output to the
front left/right output jacks is full range.
This switch position should also be used
if you are using a packaged speaker
system where the first input feed is to the
subwoofer. Although subwoofer/satellite
systems normally use the "small"
setting, some systems contain a crossover
within the subwoofer, and send filtered
sounds to small speakers. Consult your
dealer or the speaker system's owner's
manual if you are uncertain if this is an
appropriate setting.
Small: Set the switch to this position if
you have small, frequency limited
satellite type speakers that do not
reproduce sounds below 100 Hz, and
whenever a subwoofer is used. Use this
setting if you have a subwoofer satellite
system where there are separate feeds to
your subwoofer and the small satellite
speakers (but then an extra subwoofer is
neccessary for the LFE channel). When
ª
the Subwoofer Mode Switch is in the
"ON" position, front Low Frequency
Effects (LFE) audio will be routed to the
subwoofer.
2) Surround Speaker Mode
This switch determines the frequency
range of the rear surround speakers.
Select Large, None or Small depending
on the type of speakers you will be using.
The factory default setting is "Small".
