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. (

about
"Speakers
A"
and "Speakers B")
• 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
speaker set, use speakers whose impedance is 4 to
16
n,
and set the speaker impedance setting on the
receiver to 4
or
6
Q
(
~
page 13). When the impedance
of
the speaker to be used is less than 6
n,
set the
speaker impedance to 4
n.
• When you connect speakers to both
SPEAKERS A
and
SPEAKERS B terminal posts and output sound
from both speaker sets simultaneously, use speakers
whose impedance is 8 to 16
n.
Set the speaker
impedance setting
on
the receiver to 4
n.
•
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 unnatura
l.
•
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.
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.

be
connected to each pair
