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. 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 Set IMPEDANCE SELECTOR to your speaker is Between 4 and 8 ohms 4Ω 8 ohms or higher 8Ω 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. 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. 17
