1. Using the remote control or front
panel controls appropriate to your
receiver, processor or pre-amp, make
note of the delay time setting you use for
normal surround listening.
2. Press the front panel DELAY
∫
button
until the delay time indicator illuminates
to show a setting that is closest to that
used with your conventional surround
system.
SYSTEM CONNECTIONS
The ADP303 may be used in one of three
operating modes, depending on the other
equipment in your system. Before
proceeding to the final adjustments,
check to make certain that the ADP303 is
connected to the components in your
system based on one of the three options
shown on the following pages. Note that
proper system calibration and operation
are dependent on making the right
connections and use of the controls as
outlined on each page.
If you will be using the ADP303 in
conjunction with an AVR80, AVI250 or
other AV receiver equipped with direct
inputs for a “6 Channel Direct”
connection via RCA jacks, use the system
configuration shown on page 8.
If you will be using the ADP303 in
conjunction with an external preamp or
surround sound processor, use the system
configuration shown on page 9.
If you will be using the ADP303 in
conjunction with an AV receiver equipped
with “pre-out/main-in” jacks for all five
audio channels, use the system
configuration shown on page 10.
Installation & Setup
Large:
Set the switch to this position
when using traditional full range
loudspeakers that are capable of
handling sounds below 100 Hz. In this
position, the output to the surround
output jacks is full range.
None:
Set the switch to this position
when no surround speakers are
connected. In this position the full range
surround audio that would otherwise be
routed to the surround channels will be
mixed in with the FRONT LEFT and
FRONT RIGHT audio.
Small:
Set the switch to this position
when using smaller bookshelf or
“satellite” speakers that have limited low
frequency range and are unable to
reproduce sounds below 100 Hz. When
the switch is in the “Small” position all
sounds below 100 Hz will be routed to the
Subwoofer output jack. When the
Subwoofer Speaker Mode switch
ª
is in
the “ON” position, LFE surround audio
will be routed to the subwoofer. When the
Subwoofer Speaker Mode Switch
ª
is in
the “OFF” position, LFE surround audio
will be routed to the front left/right
speakers.
3) Center Speakers Mode
This switch determines the frequency
range for the center channel speaker.
Select Large, None or Small depending
on the type of center channel speaker
installed. The factory default setting is
“Small”.
Large:
Set the switch to this position
when using traditional full range loud-
speakers that are capable of handling
sounds below 100 Hz.
None:
Set the switch to this position
when a center channel speaker is not
connected. Full range audio signals that
would otherwise be routed to the center
channel will be mixed in with the
FRONT LEFT and FRONT RIGHT audio.
7
Small:
Set the switch to this position
when using a smaller bookshelf or
“satellite” center speaker that has limited
low frequency range and is unable to
reproduce sounds below 100 Hz. When
the switch is in the “Small” position, LFE
Center audio will be routed to the
Subwoofer output, provided that the
Subwoofer Speaker Mode Switch
ª
is in
the “ON” position. Otherwise it’s routed
to the front speakers.
4) Subwoofer Mode
Set this switch to determine the routing
of low frequency sounds for all channels.
The factory default setting is “ON”, to
indicate that a subwoofer is present.
On: Select this position if the ADP303 is
connected to an amplifier or Receiver
equipped with a Subwoofer INPUT
terminal, or if it is directly connected to a
powered subwoofer.
Off: Select this position if a Subwoofer
will not be used.
In this position the low frequency sounds
(below 100 Hz) will be routed to the
FRONT LEFT, RIGHT and/or CENTER
terminals, depending on the setting of
the speaker switches for those channels.
5) System Reset
Once you have completed any changes to
the Speaker Selection Switches turn the
ADP303 off, and then on again to enter
the settings into the unit’s memory for
future use.
DELAY TIME ADJUSTMENT
Delay time adjustment enables you to
adjust the timing between signals at the
front and rear channels. Since the use of
the ADP303 may bypass the delay settings
in your receiver or preamp it is important
to establish a proper delay setting for use
in 6 channel operation.
