Note for connecting the speaker cords to the receiver
Remove about 10 mm of insulation at the end of the cord, then twist the exposed wires.
Connect the stripped ends of the cords to the terminals, taking care to avoid mutual contact
between the cords.
Make sure the cords are firmly connected to the speaker and receiver terminals.
To avoid short-circuiting the speakers
Short-circuiting of the speakers may damage the receiver. To prevent this, be sure to follow
these precautions when connecting the speakers. Make sure the bare wire of each speaker cord
does not touch another speaker terminal or the bare wire of another speaker cord.
Examples of poor conditions of the speaker cord
Stripped speaker cord is touching
another speaker terminal.
After connecting all the components, speakers, and AC power cord (mains lead), output a test
tone to check that all the speakers are connected correctly. For details on outputting a test tone,
see page 30.
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 currently displayed on the front panel display, the speaker may be
short-circuited. If this happens, check the speaker connection again.
Notes
• Be sure to match the speaker cord to the appropriate terminal on the components: 3 to 3, and # to #. If the
cords are reversed, the sound will be distorted and will lack bass.
• If you use front speakers with low maximum input rating, adjust the volume carefully to avoid excessive output
on the speakers.
• When connecting the stripped ends of the speaker cords, make sure the ends do not touch each other or
neighboring terminals.
