Notes on speaker system hookup

• Twist the stripped ends of the speaker cords about 2/3 inch (10 mm). Be sure to match the speaker cord to

the appropriate terminal on the components: + to + and

- to -. If the cords are reversed, the sound will be

distorted and will lack bass.

• Ifyou use front speakers with low maximum irrput

rating, adjust the volume carefully to avoid excessive output on the speakers.

Active sub woofer

To avoid short-circuiting the speakers

Short-circuiting of tile speakers may damage tile receiver. To prevent this, make sure to take the following precautions when connecting the speakers.

Make sure the stripped ends of each speaker cord do not touch another speaker terminal or the

stripped end of another speaker cord.

Speakerimpedance

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_d." Check the instruction manual supplied with your

speakers if you're not sure of their impedance. (This intormation is usually printed on a label on the back of

the speaken)

.r o

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 22.

You may connect a pair of speakers with a nominal impedance between 4 and 8 ohms to the FRONT

SPEAKERS terminals, if you set the IMPEDANCE SELECTOR to "4f_." Speakers connected to the REAR 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 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). In this case, set the iMPEDANCE SELECTOR to "4f_.".

€

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.
