Installation
Unpacking
This section describes how to connect the system to
the speakers, a TV monitor with audio / video input jacks
and other video components. You cannot connect this
system to a TV monitor which does not have a video
input connector. Be sure to turn off the power of each
component before making the connectors.
Check that you have the following items:
Main unit (1).
Subwoofer (1).
Speakers (5).
Remote control (1).
Video cable (4 feet x 1).
AM loop antenna (1).
FM antenna (1).
Batteries (2).
Inserting Batteries into the Remote
Control
You can control the system using the supplied remote.
Insert two “AA” batteries by matching the + and - on the
batteries with the markings in the battery compartment.
When using the remote, point it at the remote sensor on
the front panel of this system.
Notes:
Do not leave the remote in an extremely hot or humid
place.
Do not use a new battery with an old one.
Do not drop any foreign object into the remote casing,
particularly when replacing the batteries.
Do not expose the remote sensor to direct sunlight
or lighting apparatuses. Doing so many cause a
malfunction.
If you do not use the remote for an extended period
of time, remove the batteries to avoid possible damage
from battery leakage and corrosion.
Use only the size and type of batteries specified.
Be sure to follow the correct polarity when installing
the batteries as indicated in the battery compartment.
Reversed batteries may cause damage to the device.
Do not mix different types of batteries together
(e.g. Alkaline and Carbon-zinc) or old batteries with
fresh ones.
13
Speaker System Connection
Connect the supplied speaker system by matching the colors of the terminals and those of the cords.
The speaker cables and speaker terminals are color-coded for easier connection.
Connect the Front Left Speaker with White/Black cables to the “SPEAKER - FRONT L” White/Black terminals on
the back panel.
Connect the Front Right Speaker with Red/Black cables to the “SPEAKER - FRONT R” Red/Black terminals on
the back panel.
Connect the Rear Left Speaker with Blue/Black cables to the “SPEAKER - REAR L” Blue/Black terminals on
the back panel.
Connect the Rear Right Speaker with Gray/Black cables to the “SPEAKER - REAR R” Gray/Black terminals on
the back panel.
Connect the “CENTER” Speaker with Green/Black cables to the “SPEAKER CENTER” Green/Black terminals on
the back panel.
Connect the “SUBWOOFER” with Pink/Black cables to the “SUBWOOFER” Pink/Black terminals on the back
panel.
T o avoid short-circuiting the speakers
Make sure the stripped end of each speaker cord does
not touch another speaker terminal or the stripped
end of another speaker cord.
Examples of poor connection of the speaker cord
Stripped speaker cord is touching another speaker
terminal.
Stripped cords are touching each other due to
excessive removal of insulation.

Antenna Connections
FM ANTENNAS
FM Indoor Antenna
If you live reasonably close to a transmitter and want
to use the provided lead-type FM antenna, you will
connect it directly to the “FM 75 W” socket at the
back of the main unit. See the LOCATION OF JACKS
AND TERMINALS page for details on the location of
this socket. Fit the metal sleeve of the lead-type antenna
over the core (center) conductor of the (FM 75 W)
socket. Be sure to fully extend the FM antenna and keep
it as horizontal as possible.
Lead-type FM Antenna (75 W provided)
AM Indoor Loop Antenna
To stand the antenna on a surface, fix the claw to the
slot.
A high-performance AM loop antenna provided with the
receiver is sufficient for good reception in most areas.
Connect the loop antenna’s wires to the AM antenna
terminals as shown. Place the antenna on a shelf, for
example, or hang it on a window frame, etc., in the
direction which gives the best reception. Place it as
far away as possible from the entire system, speaker
cords and the power cord, to prevent unwanted noise.
Outdoor FM Antenna (75 W)
FM Outdoor Antenna
In an area where FM signals are weak, it will be
necessary to use a 75 W unbalanced-type outdoor
FM antenna using the optional matching transformer,
as shown. Generally, a 3-element antenna will be
sufficient, if you live in an area where the FM signals
are particularly weak, it may be necessary to use one
with 5 or more elements. Check the instructions provided with
the outdoor antenna for details on how to connect it to this
product.
AM Outdoor Antenna
If the provided AM loop antenna does not deliver
sufficient reception (because you are too far from the
transmitter or in a concrete building, etc.), it may be
necessary to use an outdoor AM antenna. Check the
instructions provided with the outdoor antenna for details on
how to connect it to this product.
Note: when connecting an outdoor AM antenna, do not
disconnect the AM loop antenna.
