Preparing Your Receiver
Connecting Speakers
Preparing the Speaker Wires
Speaker wire consists of two conductors (individual wires) encased in
insulation and is usually color-coded or marked with a ridge along one
side so you can identify each conductor. Use these markings as a guide
to help you properly connect the speakers to your receiver.
Follow these steps to prepare the speaker wires.
1. Cut the speaker wires to the necessary length.
2. Separate the wires about 4 inches on each end.
3. Using a wire stripper, carefully strip about 3 / 4 inch of insulation
from the end of each conductor.
4. Twist the end of each conductor to secure any loose wire strands.
Setting the Impedance Selector Switch
Before proceeding to speaker connection, be sure to set the IMPEDANCE
SELECTOR switch to the appropriate position. If you connect speakers
with 6- to 8-ohm impedance, set the switch to 6~LESS THAN 8 W position. If
you are using 8- to 16-ohm impedance, set it to 8~16 Ω Ω Ω Ω position.
Follow these guidelines when you select
and connect speakers.
• Only connect speakers that are rated
at between 6 and 16 Ohms.
• Be sure you properly connect all
speakers.
• Do not connect two pairs of speakers
to a single set of terminals at the
same time.
• Optimus and other high-quality speak-
ers have color-coded speaker termi-
nals (red for positive polarity and
black for negative polarity). Use these
color-coded terminals as a guide to
help you properly connect the speak-
ers to the receiver.
• Use 16-gauge (or larger) speaker wire
for all speaker connections, and con-
sider possible speaker locations be-
fore you decide how much speaker
wire you need.
