Connecting speakers
■ Note on the speaker impedance
The unit supports the following speaker impedance.
• CH.3 A/B: 4 or more (8 or more when using CH.3 A and CH.3 B at the same time)
• BRIDGE connection: 8 or more
•Other channels: 6 or more
Set the IMPEDANCE SELECTOR to the upper/lower position depending on the speakers
connected to the unit.
■ Connecting speaker cables
Speaker cables have two wires. One is for connecting the negative (-) terminal of the unit and the
speaker, and the other is for the positive (+) terminal. If the wires are colored to prevent confusion,
connect the black wire to the negative and the other wire to the positive terminal.
a Remove approximately 10 mm (0.40 in) of insulation from the ends of the speaker cable, and
twist the bare wires of the cable firmly together.
b Loosen the speaker terminal.
c Insert the bare wires of the cable into the gap on the side (upper left or bottom right) of the
terminal.
d Tighten the terminal.
Using a banana plug
(U.S.A., Canada, China, Taiwan and Australia models only)
a Tighten the speaker terminal.
b Insert a banana plug into the end of the terminal.
Upper position
Select this option when your speaker system meets one of the followings.
• When connecting speakers with impedance of less than 8 (4 or more) to the CH.3
A or CH.3 B terminal
• When using two pairs of speakers connected to the CH.3 A/B terminals at the same
time (be sure to use 8-ohm speakers for both CH.3 A and CH.3 B)
• When simultaneously using speakers of 8 Ω or more connected to both CH.3 A
terminals and CH.4 terminals.
• When connecting speakers with impedance of less than 8 (6 or more) to speaker
terminals other than CH.3 A or CH.3 B
Lower position
(default)
Select this option when using speakers with impedance of 8
or more only.
