Hooking Up and Setting Up the Speaker System Speaker System Hookup 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. 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 "8Ω." 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 "4Ω." 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. 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. 16
