heating vents, stoves, or other appliances that generate heat.
It also should not be placed in temperatures less than 5°C
(41“F) or higher than 35°C (95°F).
Mounting surface —Place the unit on a flat, even surface.
Ventilation —The unit should be situated with adequate
space around it so that proper heat ventilation is assured.
Allow 10 cm (4 in.) clearance from the rear and the top of the
unit, and 5 cm (2 in.) from each side.
-Do not place the unit on a bed, rug, or similar surface that
may block the ventilation openings.
-Do not install the unit in abookcase, cabinet, or airfight
rack where ventilation may be impeded.
Objects and liquid entry —Take care that objects or liquids
do not get inside the unit through the ventilation openings.
Carts and stands —When
placed or mounted on a stand
or cart, the unit should be
moved with care.
Quick stops, excessive force,
and uneven surfaces may
cause the unit or cart to overturn
or fall.
Wall or ceiling mounting —The unit should not be mounted
on a wall or-ceiling, unless specified in the Operating
Instructions.
Electric Power
1Power sources —Connect this unit only to power sources
specified in the Operating Instructions, and as marked on
the unit.
2Polarization —As asafety feature, some units are equipped
with polarized AC power plugs which can only be inserted
one way into apower outlet. If it is difficult or impossible to
insert the AC power plug into an outlet, turn the plug over
and try again. If it is not still inserted easily into the outlet,
please call aqualified service technician to service or replace
the outlet, To avoid defeating the safety feature of the
polarized plug, do not force it into apower outlet.
3AC power cord
-When disconnecting the AC power cord, pull it out by the
AC power plug. Do not pull the cord itself.
-Never handle the AC power plug with wet hands, as this
could result in fire or shock.
-Power cords should be firmly secured to avoid being
severely bent, pinched, or walked upon. Pay particular
attention to the cord from the unit to the power socket.
-Avoid overloading AC power plugs and extension cords
beyond their capacity, as this could result in fire or shock.
4Extension cord — To help prevent electric shock, do not
use apolarized AC power plug with an extension cord,
receptacle, or other outlet unless the polarized plug can be
completely inserted to prevent exposure of the blades of the
plug.

continues to flow to the unit, even when the power is turned
off
Outdoor Antenna
1Power lines —When connecting an outdoor antenna, make
sure it is located away from power lines.
2Outdoor antenna grounding —Be sure the antenna system
is properly grounded to provide protection against unexpected
voltage surges or static electricity build-up. Article 810 of the
National Electrical Code, ANS1/NFPA70, provides information
on proper grounding of the mast, supporting structure, and
the lead-in wire to the antenna discharge unit, as well as the
size of the grounding unit, connection to grounding terminals,
and requirements for grounding terminals themselves.

CONNECTING SPEAKERS @
Speaker terminals
Connect front speakers (system Aand/or B), acenter speaker
and surround speakers to the corresponding speaker terminals
on the unit:
-the front speaker cords to the FRONT SPEAKERS terminals
-the center speaker cord to the CENTER SPEAKER terminals
-the surround speaker cords to the SURROUND SPEAKERS
terminals.
For more powerful bass, connect asub woofer with abuilt-in
amplifier to the SUPER WOOFER djack.
Speaker impedance
●Front and center speakers
The SPEAKER IMPEDANCE SELECTOR on the rear should be
set to the position that matches the impedance value of the front
and center speakers.
When using 4ohm speakers, set the selector to 4Q. When using
8ohm speakers, set the selector to 8Q. Please unplug the AC
cord before setting the selector.
●Surround speakers and super woofer
The SPEAKER IMPEDANCE SELECTOR has no effect on the
SURROUND SPEAKERS terminals and the SUPER WOOFER
~jack. For the surround speakers and sub woofer, use speakers
of 8ohms or more.
Connecting +to +, -to -terminals
To get the proper sound effect, the speaker terminals on the unit
and the speaker should be connected with proper polarity; the +
terminal on the unit should be connected to the +terminal on
the speaker (and –to –).
m
●Be sure to connect the speaker cords correctly as shown in
the illustration on the right column. Improper connections can
cause shorl circuits in the SPEAKER(S) terminals.
●Do not leave objects generating magnetism near the speakers.
●When using asub woofer, select the speaker system A(see
page 6). Otherwise no sound can be heard from it.
POSITIONING THE SPEAKERS
Position the speakers to make the most of the Dolby Pro Logic
or DSP effect (see “DOLBY PRO LOGIC).
@Front speakers
@Center speaker
Position in the center of the two front speakers. In addition,
position on or below the TV set, if connecting aTV set to the
unit.
@Surround speakers
Place the surround speakers directly to the side of or slightly
behind the listening area. Align them horizontally, about 1
meter (3.2 feet) above ear height.
m
●Sound is heard from the surround speakers when the DSP is
set to on.
●Sound is heard from the center speaker mainly when the Dolby
Pro Logic is set to on. Note that when you select the PHANTOM
mode of the Dolby Pro Logic, the center speaker is muted.
(For details, see “DOLBY PRO LOGIC”).
Front smeakers
Lift up the terminal flap,
insert the speaker cord lead
into the terminal slot, then
close the flap. Check that the
cord is connected securely.

To stand the AM loop antenna on asurface
Fix the claw to the slot as shown in the illustration.
To position the antennas
FM feeder antenna:
Extend this antenna horizontally in aTshape and fix its ends to
the wall.
AM loop antenna:
Position for the best reception.
m
●Do not bring the FM antenna near metal objects or curtain rails.
●Do not bring the AM antenna near other external equipment,
the unit itself, the AC power cord or speaker cords, as noise
will be picked up.
●Do not unwind the AM loop antenna wire.
CONNECTING AN OUTDOOR ANTENNA
For better FM reception, use of an outdoor antenna is
recommended. Connect the outdoor antenna to the FM 75 Q
terminals.
ABOUT THE REMOTE CONTROL
Inserting batteries
Detach the battery cover on the rear of the remote control and
insert two R6 (size AA) batteries.
R6(AA)
When to replace the batteries
The maximum operational distance between the remote control
and the sensor on the unit should be approximately 5meters
(16 feet). When this distance decreases, replace the batteries
with new ones.
Using the remote control
The instructions in this manual refer mainly to the buttons on the
main unit. Buttons on the remote control with the same names
as those on the main unit can be used as well.
m
●If the unit is not going to be used for an extended period of
time, remove the batteries to prevent possible electrolyte
leakage.
●The remote control may not operate correctly when:
-The line of sight between the remote control and the remote
sensor in the display window is exposed to intense light, such
as direct sunlight.
-Other remote controls are used nearby (those of television,
etc.)

The Dolby Pro Logic feature and the center and surround
speakers (standard) assure full-scale home theater sound. When
playing back laser discs or video software that have been
recorded in Dolby Surround, astonishingly realistic sound
surrounds the listener to create anew level of audio/visual
entertainment.
Independent control of the four channels allows the listener to
enjoy the same type of sound reproduction experienced in movie
theaters. Voices are reproduced in the front and center sound
field, while ambient sounds like cars and crowds are reproduced
on all sides of the listener for an incredibly lifelike audio/video
experience. Please read the following carefully to “tune” the
system’s output to match the characteristics of your listening
space.
Check the following:
*Before using the DOLBY PRO LOGIC, adjust the proper
balance of the speaker sound levels (see page 13).
●Make sure the speakers are properly connected and positioned
(see pages 3 and 4).
●Make sure the TV set and video unit are properly connected
(see page 3).
●Make sure the laser disc and video tape, etc., support

SELECTING DOLBY PRO LOGIC
The optimal Dolby Pro Logic mode depends on the type and

Aiwa speakers should be used for all channels, for example, the
SX-R2000 for surround speakers, the SX-C2000 for acenter
speaker and the SX-AV2000 for front speakers. Check your
current type and placement of the speakers and select the
recommended Dolby Pro Logic mode accordingly.
