03 Connecting your equipment Connecting the speakers Each speaker connection on the receiver comprises a positive (+) and negative (-) terminal. Make sure to match these up with the terminals on the speakers themselves. CAUTION ! These speaker terminals carry HAZARDOUS LIVE voltage. To prevent the risk of electric shock when connecting or disconnecting the speaker cables, disconnect the power cord before touching any uninsulated parts. ! Make sure that all the bare speaker wire is twisted together and inserted fully into the speaker terminal. If core wires touch each other or come in contact with the rear panel or the metal parts of other speaker terminals, the protective circuit may be activated, setting the power to the standby mode. Bare wire connections CAUTION Make sure that all speakers are securely installed. This not only improves sound quality, but also reduces the risk of damage or injury resulting from speakers being knocked over or falling in the event of external shocks such as earthquakes. 1 Twist exposed wire strands together. 2 Loosen terminal and insert exposed wire. 3 Tighten terminal. 1 2 3 10 mm (3/8 in.) Note ! Please refer to the manual that came with your speakers for details on how to connect the other end of the speaker cables to your speakers. ! Use an RCA cable to connect the subwoofer. It is not possible to connect using speaker cables. ! If you have two subwoofers, the second subwoofer can be connected to the SUBWOOFER 2 terminal. Connecting two subwoofers increases the bass sound to achieve more powerful sound reproduction. In this case, the same sound is output from the two subwoofers. Banana plug connections If you want to use speaker cables terminated with banana plugs, screw the speaker terminal fully shut, then plug the banana plug into the end of the speaker terminal. Bi-amping your speakers Bi-amping is when you connect the high frequency driver and low frequency driver of your speakers to different amplifiers for better crossover performance. Your speakers must be bi-ampable to do this (having separate terminals for high and low) and the sound improvement will depend on the kind of speakers you're using.

Most speakers with both High and Low terminals have two metal plates that connect the High to the Low terminals. These must be removed when you are bi-amping the speakers or you could severely damage the amplifier. See your speaker manual for more information. ! If your speakers have a removable crossover network, make sure you do not remove it for biamping. Doing so may damage your speakers. Bi-wiring your speakers Your speakers can also be bi-wired if they support bi-amping. ! With these connections, the Speaker System setting makes no difference. CAUTION ! Don't connect different speakers from the same terminal in this way. ! When bi-wiring as well, heed the cautions for bi-amping shown above. % To bi-wire a speaker, connect two speaker cords to the speaker terminal on the receiver. Using a banana plug for the second connection is recommended. 16 En
