Connecting Your Speakers-Continued Speaker Connection Precautions Read the following before connecting your speakers: • You can connect speakers with an impedance of between 8 and 16 ohms. If you use speakers with a lower impedance, and use the amplifier at high volume levels for a long period of time, the built-in amp protection circuit may be activated. • Disconnect the power cord from the wall outlet before making any connections. • Pay close attention to speaker wiring polarity. In other words, connect positive (+) terminals to only positive (+) terminals, and negative (-) terminals to only negative (-) terminals. If you get them the wrong way around, the sound will be out of phase and will sound unnatural. • Unnecessarily long or very thin speaker cables may affect the sound quality and should be avoided. • Be careful not to short the positive and negative wires. Doing so may damage the AV receiver. • Don't connect more than one cable to each speaker terminal. Doing so may damage the AV receiver. • Don't connect a speaker to several terminals. Using the Speaker Terminal Tool The supplied speaker terminal tool makes it easy to tighten and loosen the speaker terminals. If you are using banana plugs, to ensure optimum sound quality, tighten the speaker terminal before inserting the banana plug. Connecting Speakers The AV receiver's positive (+) speaker terminals and speaker's positive (+) terminals are color-coded for ease of identification. (The negative (-) speaker terminals are all black.) Match the color of each cable to the corresponding speaker terminal.

Make sure that the bare wire is touching the inside of the pole. Screw the terminal tight. 2 On the speakers, while pressing the terminal lever, insert the wire into the hole, and then release the lever. 3 Using the supplied RCA cable, connect the AV receiver's SUBWOOFER PRE OUT to LINE INPUT on the subwoofer. Make sure the cable is plugged all the way. The following illustration shows which speaker should be connected to each pair of terminals.
