Speaker system connections
• Connect the speaker terminals with the speakers making sure that
like polarities are matched (< with <, > with >). Mismatching of
polarities will result in weak central sound, unclear orientation of
the various instruments, and the sense of direction of the stereo
being impaired.
• When making connections, take care that none of the individual
conductors of the speaker cord come in contact with adjacent
terminals, with other speaker cord conductors, or with the rear
panel.
NOTE:
NEVER touch the speaker terminals when the power is on.
Doing so could result in electric shocks.
1. Loosen by turning
counterclockwise.
CENTER SPEAKER SYSTEM
Connection jack for subwoofer with built-in amplifier
(super woofer), etc.
To achieve Dolby Digital playback effect, use a unit
that can sufficiently reproduce frequencies of
under 80 Hz.
Connecting the speaker cords
2. Insert the cord. 3. Tighten by turning
clockwise.

SURROUND SPEAKER SYSTEMS
• Precautions when connecting speakers
If a speaker is placed near a TV or video monitor, the colors on the screen may be disturbed by
the speaker's magnetism. If this should happen, move the speaker away to a position where
it does not have this effect.
Speaker Impedance
• When speaker systems A and B are use separately, speakers with
an impedance of 6 to 16 Ω/ohms can be connected for use as front
speakers.
• Be careful when using two pairs of front speakers (A + B) at the
same time, since use of speakers with an impedance of 12 to 16
Ω/ohms.
• Speakers with an impedance of 6 to 16 Ω/ohms can be connected
for use as center and surround and surround back speakers.
• The protector circuit may be activated if the set is played for long
periods of time at high volumes when speakers with an impedance
lower than the specified impedance are connected.
Banana plug
Turn clockwise to tighten, then insert the
banana plug.
