• Never short circuit the + and – speaker cords.
• If the left and right speakers are connected inversely or the
speaker cords are connected with reversed polarity, the
sound will be unnatural with ambiguous acoustic imaging.
Be sure to connect the speakers correctly.
Speaker impedance
After confirming the speaker impedance indications printed
on the rear panel of the receiver, connect speakers with
matching impedance ratings. Using speakers with a rated
impedance other than that indicated on the rear panel of
the receiver could result in malfunctions or damage to the
speakers or receiver.
