Hooking Up and Setting Up the Speaker System
To avoid short-circuiting the speakers
Short-circuiting of the speakers may damage the receiver.
To prevent this, make sure to take the following
precautions when connecting the speakers.
Make sure the stripped ends of each speaker cord
does not touch another speaker terminal or the
stripped end of another speaker cord.
Examples of poor conditions of the speaker cord
Stripped speaker cord is touching another speaker terminal.
Stripped cords are touching each other due to excessive
removal of insulation.
After connecting all the components, speakers,
and AC power cord, output a test tone to check
that all the speakers are connected correctly. For
details on outputting a test tone, see page 21.
If no sound is heard from a speaker while outputting a
test tone or a test tone is output from a speaker other than
the one whose name is currently displayed on the
receiver, the speaker may be short-circuited. If this
happens, check the speaker connection again.
Speaker impedance
To enjoy multi channel surround, connect front, center,
and rear speakers with a nominal impedance of 8 ohms or
higher, and set the speaker IMPEDANCE SELECTOR to
“8
Ω
.” Check the instruction manual supplied with your
speakers if you’re not sure of their impedance. (This
information is usually printed on a label on the back of
the speaker.)
If you connect any speaker to the FRONT, CENTER or
REAR SPEAKERS terminals with a nominal impedance
between 4 ohms and 8 ohms, you must set the
IMPEDANCE SELECTOR to “4
Ω.
”
Notes
• Be sure to connect front speakers with a nominal impedance of
8 ohms or higher if you want to select both sets (A+B) of front
speakers (see page 27).
• Speakers with an impedance of less than 4 ohms cannot be
used.
