Connecting Speakers
—Continued
Before you connect the supplied speakers, read the fol-
lowing:
• Disconnect the power cord from the wall outlet.
•Pay close attention to speaker wiring polarity. In other
words, connect positive (+) terminals only to positive (+)
terminals, and negative (–) terminals only to negative (–)
terminals. If you get them the wrong way around, the
sound will be out of phase and will sound odd.
• Only use speakers with an impedance of 8 ohms or
higher. 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 posi-
tive and negative connections.
Doing so may damage the
HT-R820THX.
• Don’t connect more than one
cable to each speaker terminal.
Doing so may damage the
HT-R820THX.
• 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.
Connecting speaker Set A
The HT-R820THX’s positive (+) speaker terminals and
speaker’s positive (+) terminals are color-coded for ease
of identification. (The negative (–) speaker terminals are
all black.) Match the color of each cables to the corre-
sponding apeaker terminal.

The following illustration shows which speakers should be connected to which terminals.

Strip 3/8" (10 mm) of insula-
tion from the ends of the
speaker cables, and twist the
bare wires tightly, as shown.

While pressing the lever, insert
the wire into the hole, and then
release the lever.
Make sure that the terminals are
gripping the bare wires, not the
insulation.
