FIRST THINGS FIRST
CONNECTING, PLACING &
BALANCING THE SPEAKERS
CONNECTING THE WIRES
Each speaker - the two main, two surround and one
central - has a designated set of terminals on the back
panel of the central unit.
Uncoil the speaker wires and locate the bare ends.
Press and hold down on the tab to open the red
terminal, then insert the red (+) wire. Release hold to
close tab. Use the same procedure for black (0 wire
into black terminal.
WARNING: Be sure to follow these instructions
carefully. The system can be damaged if speakers are
improperly connected.
SETTING UP FOR SURROUND SOUND
THE MAIN SPEAKERS
The two main speakers should be set between six and
10 feet apart. Putting the speakers any cioser or any
farther apart may result in distorted sound.
The speakers should also form a 45 degree angle to
the central listening point in the room, creating a
triangle of listening enjoyment,
NOTE: You may need to place the main speakers closer
together when not utilizing the center speaker. Do
not place them so close, however, that their
magnetic fields affect the TV’s reception.
THE CENTER SPEAKER
For optimal performance, you shouid try to place the
center speaker as close as possible to the same height
as the left and right main speakers. You shouid also
try to align all three speakers, or set the center
speaker slightly behind the left and right mains.
However, you should never place the center speaker
forward of the left and right mains, as this will distort
the sound for those listeners not seated in the center
of the room.
THE SURROUND SPEAKERS
Placement of the surround speakers for optimal
performance is truly subject to the size and type of
room in which the system is to be placed.
The following are a few position suggestions.
1. Set the speakers on the side walls, facing each
other, approximately two to three feet above the
listeners head.
