Connecting to Audio Components Connecting the Speakers
Speaker wires are color-coded to match the
terminals. Connect the speaker wire from the
back of each speaker to the corresponding
color terminal at the back of the unit. Press
down the tab to open the terminal and insert
the wire. Release the tab to lock wire in
the terminal.
When connecting the speakers, make sure the
polarities (“+” speaker wire to “+” on the unit.
For example, red wire to red terminal on the
unit) of speaker wires and terminals match.
If the cords are reversed, the sound will
be distorted. Do not let the speaker wires
touch each other, it will damage
the speaker.
When connecting subwoofer, connect
subwoofer control cable (red/black striped) at
the back of the subwoofer to the subwoofer
control jack on the unit’s rear panel, then press
POWER ON/OFF on the subwoofer speaker to
turn it on.

Set up and Maintenance of
the Unit
Provide spaces for sufficient ventilation
as indicated:
• Do not connect to the AC power cords until
all connections are completed.
• Do not use your set immediately after
transferring it from a cold place to a warm
place: there is risk of condensation.
• Do not expose your set to water and
excessively high temperatures.
• After having disconnected your set, clean the
case with a soft cloth, or with a slightly damp
leather chamois. Never use strong solvents.
Protect your Components from
Overheating
• Do not block ventilation holes in any
component. Arrange the components so that
air can circulate freely.
• Do not stack components directly on top of
each other.
• Do not place the unit near other components
that generate heat such as heating vents.
• Allow adequate ventilation when placing
your components in a stand.
• Place an amplifier near the top shelf of the
stand so heated air rising from it will not
affect other components. If you have a
satellite receiver, you should place it on the
top shelf.
TV Connections
TVs with RF input may need a RF modulator
(not included) for inputting audio signals.
The illustration shown above may varies from
your actual RF modulator, please refer to your
RF modulator manual.
Connecting the Antennas
Connect the AM and FM antennas to the AM
and FM terminals on the system’s back panel.
They must be hooked up in order to receive
clear reception. For FM reception, extend
antenna to its full length. For AM reception,
rotate the antenna horizontally to get
better reception.
AM Loop Antenna and FM Indoor Antenna
1. Uncoil the antenna wire and locate the base
end of the AM antenna.
2. Press down on the antenna tab to open
the terminal.
3. Insert the antenna wires into the terminal
and release the tabs to secure the wires
in place.
4. Make sure the white wire on the AM loop
antenna is inserted into the AM LOOP
terminal and other wire is inserted into the
ground loop terminal.

the outlet completely, turn the
plug over and try to insert it the other way. If it
still won’t fit, contact a qualified electrician to
change the outlet, or use a different one. Do
not attempt to bypass this safety feature.
CAUTION: To prevent electric shock, match
wide blade of plug to wide slot, fully insert.

Portable Cart Warning
Positioning Speakers
1. Left, Right (Front Speakers)
Front speakers carry primarily music and
sound effects.
2. Center
In surround mode, the center speaker carries
most of the dialog as well as music and effects.
It should be set between the left and
right speakers.
3. Surround (Rear Speakers)
The rear speakers’ overall sound balance should
be as close as possible to the front speakers.
Proper placement is vital to establish an evenly
distributed sound field.
Subwoofer
A subwoofer is designed to reproduce powerful
low bass effects (explosions, the rumble of
spaceships, etc.) which dramatically heighten
the action on the screen.
Magnetic Shielding
Speakers placed less than two feet from the TV
set must be magnetically shielded in order to
prevent picture distortion. Front speakers
provided with this unit are magnetically
shielded to protect your TV set.
Front Speaker Placement
Follow the suggestions for speaker placement
below to get the best results.
Alignment
Align the center speaker evenly with (A) or
slightly behind (B) (the left and right speakers),
but not ahead of them.
Angle
Place the left and right speakers to form a 45-
degree angle with your favorite viewing
position to duplicate the soundtrack
mixer’s perspective.
Height
The mid- and high-frequency drivers of the
three front speakers should be as close as
possible to the same height. This often requires
placing the center speaker directly on top (A)
or beneath (B) the TV set.
Better Surround Placement
Location
If possible, place surround speakers to either
side of the listening area, not behind it.
Height
If space permits, install surround speakers 2-3
feet above viewers. This helps to minimize
localization effects.
Aiming
Aim surround speakers straight across the
room, not down at viewers, to help create a
more open, spacious surround sound field.
Alternative Surround Placement
Rear wall
If rear wall mounting is the only choice, aim
the speakers at each other (A), towards the
front (B) or towards the sidewalls (C, D).
Experiment with placement until sounds seem
to surround you, rather than come from
behind you.
No adjacent walls
Surround speakers can go on stands facing
each other to approximate sidewall mounting
(A), or to the sides or rear of the viewing area,
aimed upwards; they can go right on the floor,
or preferably, a few feet off the floor such as
on end tables (B).
Front Surround Mode
Speaker Placement
Configuration 1
Follow the suggestion for speaker placement in
the section before.
Configuration 2
If placing the rear speakers (surround speakers)
at the back is not a good choice for you, you
can use the Front Surround sound Effect(FSsE).
Follow the following instruction for setting
the speakers. (See section “Front Surround
Sound Effect (FSsE) Setting” under “Advanced
Sound Control” for details).
Mounting the Speakers
1. Place the front speaker upside down.
2. Slide in the hinge to the bottom of the front
speaker until the ‘click’ sound is heard.
3. Slide in the rear speaker to the hinge until
the ‘click’ sound is heard.
4. Attach the four rubber feet provided to the
top of the front speaker.
Adjusting the Angle of the Speakers
To achieve the best Front Surround sound
Effect (FSsE), adjust the mounted front left and
the rear left speakers to the left for an angle of
25
o
- 45
o
from the center.
Adjust the mounted front right and rear right
speakers to the right in the same way.
After adjusting the angle, the speaker should
look like this illustration.
Disconnecting the Speakers
1. To unlock the speakers, press and hold the
hinge spring as illustrated below.
2. Slide out the rear speaker from the hinge.
3. Press and hold the two hinge springs.
4. Slide out the hinge from the front speaker.
