Connecting your equipment

Connecting the speakers
Each speaker connection on the amplifier 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 any of the bare speaker wire touches the back panel it may cause the power to cut off as a safety measure.

� When placing speakers near the TV, we recommend using magnetically shielded speakers to prevent possible interference, such as discoloration of the picture when the TV is switched on. If you do not have magnetically shielded speakers and notice discoloration of the TV picture, move the speakers farther away from the 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 titled slight 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. � To achieve the best possible surround sound, install your speakers as shown below. Be sure all speakers are installed securely to prevent accidents and improve sound quality.

Bare wire connections

Make sure that the speaker cable you�re going to use is properly prepared with about 10 mm of insulator stripped from each wire, and the exposed wire strands twisted together (fig. A). To connect a terminal, unscrew the terminal a few turns until there is enough space to insert the exposed wire (fig. B). Once the wire is in position, tighten the terminal until the wire is firmly clamped (fig. C).

Important � 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. � If you are using a THX certified subwoofer use the THX INPUT jack on the subwoofer (if your subwoofer has one) or switch the filter position to THX on your subwoofer.

Placing the speakers
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.

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.
