When connecting 6-ohm speakers
Set the unit's speaker impedance to "6 Ω MIN". For details, see "Setting the
speaker impedance" in the Owner's Manual.
Precautions for connecting speaker cables
• Be sure that the unit and subwoofer are turned off.
• Prepare speaker cables in a place away from the unit, to avoid accidentally
dropping wire strands into the unit's interior which could result in a short
circuit or malfunction of the unit.
• Improper connection of speaker cables could cause a short circuit resulting
in damage to, or malfunctioning of, the unit or speakers.
– Carefully remove approximately 10 mm
(3/8") of insulation from the speaker-
connection ends of the cables, and twist
the bare wires of each speaker cable
together firmly.
– Do not allow the bare wires of separate speaker
cables to come into contact with one another.
– Do not allow speaker cable bare wires to come into
contact with metal parts on the unit (rear panel and
screws).
If "Check SP Wires" is shown on the front display when the unit is turned on,
turn off the unit and be sure that speaker cables have not caused a short
circuit.
