Hooking Up and Setting Up the Speaker System
Speaker impedance
Set the IMPEDANCE SELECTOR for the front speakers as
indicated in the table below. 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 the nominal impedance of
your speaker is
Between 4 and 8 ohms
8 ohms or higher
Speakers connected to the SURROUND and CENTER
SPEAKERS terminals must have a nominal impedance of
8 ohms or higher (regardless of the setting of the
IMPEDANCE SELECTOR).
Note
Be sure to turn the power off when setting the IMPEDANCE
SELECTOR.
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 23.
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.
To avoid damaging your speakers
Make sure that you turn down the volume before you
turn off the receiver. When you turn on the receiver, the
volume remains at the level you turn off the receiver.
