Surround back speakers
Surround back speakers are required when a full 7.1-chan-
nel system is installed.
Speakers should be placed on a rear wall, behind the lis-
tening position.
The center of the speaker should face into the room.
Subwoofer
We recommend using a subwoofer to have maximum bass
effect. Subwoofer bears only low frequency range so you
can place it any where in the room.
HEIGHT OF THE SPEAKER UNITS
Front left and right speakers, and a center speaker
Align the tweeters and mid-range drivers on the three front
speakers at the same height, as best as possible.
Surround left and right speakers, and surround back
speaker
Place the surround left, right and surround back speakers
higher than your ears by about 70cm -1m.
Also place the speakers at the same height, as best as pos-
sible.
Note:
• Use magnetically-shielded speakers for front left, right
and the center speakers when the speakers are installed
near the TV and the TV is a monitor type.
CONNECTING SPEAKER WIRE
1. Strip away approx. 10 mm of wire insulation.
2. Twist the bared wire ends tight, to prevent short circuits.
3. Loosen the knob by turning it counterclockwise.
4. Insert the bare part of the wire into the hole in side of
each terminal.
5. Tighten the knob by turning it clockwise to secure the
wire.
Caution:
• Be sure to use speakers with the specified impedance as
shown on the rear panel of this unit.
• To prevent damage to circuitry, do not let the bare speak-
er wires touch each other and do not let them touch any
metal part of this unit.
• Do not touch the speaker terminals when the power is on.
It may cause you to receive an electric shocks.
• Do not connect more than one speaker cable to one
speaker terminal. Doing so may damage this unit.
Note:
• Be sure to connect the positive and negative cables for
the speaker properly. If they are miss connected, the sig-
nal phase will be reversed and the signal quality will be
corrupted.
CONNECTING A SUBWOOFER
Use the PRE OUT SUBWOOFER jack to connect a powered
subwoofer (power amplifier built in ).
If your subwoofer is a passive type (power amplifier is not
built in), connect a monaural power amplifier to the PRE
OUT SUBWOOFER jack and connect the subwoofer to the
amplifier.
