03 Connecting your equipment Layout as seen from the side TFwL / TFwR TMdL / TMdR TBwL / TBwR Height of top speakers (between two times to three times the height of the front listener speakers) FL / FR 55° 65° 30° 125° 100° 150° Height of Front Listener Speakers 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. This unit supports speakers with a nominal impedance of 4 W to 16 W. 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 any of the bare speaker wire touches the back panel it may cause the power to cut off as a safety measure. Bare wire connections ! The height of the Top Forward, Top Middle and Top Backward speakers mounted on the ceiling should preferably be no more than three times the height and no less than two times the height of the front speakers at listener height. ! The Top Forward, Top Middle and Top Backward speakers should be directed straight down, rather than directed at a central listener position. ! We recommend that the top middle speakers be installed slightly forward from right above. 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 (6 ft. to 9 ft.) 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 (2 ft. to 3 ft.) higher than your ears and tilted slightly downward. Make sure the speakers don't face each other. For DVD-Audio, 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. 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.) Notes ! 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. 25
