Onkyo TX-8011 - Manual (Page 11)

Connections
Before you connect your speakers, read the following:
• Disconnect the power cord from the wall outlet.
• Read the instructions supplied with your speakers.
• Pay close attention to speaker wiring polarity. In other
words, connect positive (+) terminals only to positive
(+) terminals, and negative (–) terminals only to nega-
tive (–) terminals. If you get them the wrong way
around, the sound will be out of phase and will sound
odd.
• The impedance of each speaker connected to this unit
must be no lower than 4 ohms. If you’re using only
speakers A or speakers B, the minimum speaker
impedance is 4 ohms. If you’re using both speakers A
and speaker B, the minimum speaker impedance is 8
ohms. If you use speakers with a lower impedance,
and use the amplifier at high volume levels for a long
period of time, the built-in protection circuit may be
activated.
• Unnecessarily long or very thin speaker cables may
affect the sound quality and should be avoided.
• Be careful not to short the positive
and negative connections. Doing so
may damage the TX-8011.
• Don’t connect more than one cable
to each speaker terminal. Doing so
may damage the TX-8011.
• If you want to connect a single speaker instead of a
pair, connect it to either the left or right speaker termi-
nals, not both.
Maker sure that the speaker connectors are gripping the
bare wires, not the insulation.
The following illustration shows which speakers should be connected to which terminals.

1 Strip 3/8" (10 mm) of
insulation from the
ends of the speaker
cables, and twist the
bare wires tightly.
2 Push the lever to open the
hole, insert the bare wire
into the hole, and then
push the lever again to
close the hole, thereby
securing the wire.
