03 Connecting your equipment Some tips for improving sound quality Where you put your speakers in the room has a big effect on the quality of the sound. The following guidelines should help you to get the best sound from your system. ! The subwoofer can be placed on the floor. Ideally, the other speakers should be at about ear-level when you're listening to them. Putting the speakers on the floor (except the subwoofer), or mounting them very high on a wall is not recommended. ! For the best stereo effect, place the front speakers 2 m to 3 m apart, at equal distance from the TV. ! If you're going to place speakers around your CRT TV, use shielded speakers or place the speakers at a sufficient distance from your CRT TV. ! If you're using a center speaker, place the front speakers at a wider angle. If not, place them at a narrower angle. ! Place the center speaker above or below the TV so that the sound of the center channel is localized at the TV screen. Also, make sure the center speaker does not cross the line formed by the leading edge of the front left and right speakers. ! It is best to angle the speakers towards the listening position. The angle depends on the size of the room. Use less of an angle for bigger rooms. ! Surround and surround back speakers should be positioned 60 cm to 90 cm higher than your ears and tilted slightly downward. Make sure the speakers don't face each other. For DVDAudio, the speakers should be more directly behind the listener than for home theater playback. ! Try not to place the surround speakers farther away from the listening position than the front and center speakers. Doing so can weaken the surround sound effect. 18 En 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 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. 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.
