Connecting Your Speakers
Disconnect the power cord from the wall outlet before making any connections.
15mm

<=
Strip about
15
mm (5/8
inch)
of
insulation from
the ends
of
the speaker
cables, and
twist
the bare
wires tightly, as shown.
Unscrew the terminal.
Screw the terminal tight.
Fully insert the bare
wires.
Read the instructions supplied with your speakers.
Pay close attention to speaker wiring polarity.
In
other
words, connect positive (+) terminals only to positive
(+) terminals, and negative
(-)
terminals only to
negative
(-)
terminals.
If
you get them the wrong way
around, the sound will be out
of
phase and will sound
unnatural.
Unnecessarily long or very thin speaker cables may
affect the sound quality and should be avoided.
Be careful not to short the
positive and negative wires.
Doing so may damage the
receiver.
Don't
connect more than one
cable to each speaker
terminal. Doing so may
damage the receiver.
Don't
connect a speaker to more than one pair
of
speaker terminals.

The receiver allows you to connect two sets
of
speakers.
When two sets
of
speakers are connected, you can select
which speaker set outputs sound or use both sets to
output sound simultaneously.
When you connect one set
of
speakers
to
either
SPEAKERS A or SPEAKERS B terminal posts, or
when you connect two sets
of
speakers to both speaker
terminal posts and output sound only from either
speakerset, use speakers whose impedance is between
4 and 16 ohms.
When you connect speakers to both SPEAKER A and
SPEAKER B terminal posts and output sound from
both speaker sets simultaneously, use speakers whose
impedance is between 8 and
16
ohms.
Note:
If
you make an incorrect setting for the speakers or the
impedance values, the built-in protection circuit may be
activated resulting
in
no sound output from speakers.
The following illustration shows which speaker should
be connected to each pair
of
terminals.
