■ Preparing the speaker cables
1
Cut the included speaker cable to suitable
lengths for the front, center, and surround
speakers and a subwoofer. You need six cables.
2
Remove about 10 mm (3/8") of insulation from
the end of each speaker cable.
3
Twist the bare wires tightly so the individual
strands are not splayed.
Notes
• Make the speaker cables as short as possible. Do not
bundle or roll up excess cable.
• Be careful not to injure yourself while preparing the
speaker cables.
■ Operating the speaker terminals
1
Press and hold the terminal tab.
2
Insert the bare wire.
3
Release the tab so that it closes securely on the
bare wire, not the insulation.
4
Test the security of the connection by pulling
gently on the cable.
Notes
• Make sure the bare wires do not touch each other, as
this could damage the speaker or the amplifier.
• If the connections are faulty, you will hear no sound
from the speakers.
