Notice INFINITY Alpha 40

« ct the loudspeakers from any damage due to rough handling during shipment. We strongly suggest that you keep the packing material for future purposes, in case you move or if your loudspeakers should require service. POSITIONING Proper positioning of the speakers within the listening room is of primary importance in order to achieve the best possible sound. Room reflections, furniture placement, heavy drapes, window reflections and so on can influence sonic quality, balance and the stereo image. It is essential to experiment with different locations to determine which placement offers the best overall balance and imaging. For the best stereo effect, the speakers should be placed at least 2 to 3 meters apart. At times, angling the speakers slightly inward toward the listening position will add to overall spaciousness and deliver a more realistic sound stage. Try to avoid placing the speakers directly against the wall, or in corners of the room because this may sacrifice depth and image and create excessive boominess. If you must place the speakers higher than ear level tilt them downward to direct the tweeters toward your ears. INSTALLATION OF THE SPIKED FEET All floor standing models come with spiked feet to isolate the speaker from floor vibrations. To install the spiked feet follow these directions: 1. Turn the speaker upside down with the bottom of the enclosure facing upwards. 2.Thread a nut onto each spiked foot until the nut reaches the unthreaded section. 3.Screw the spiked feet into the threaded mounting sockets. 4.Adjust the spiked feet so they all are at the same height, then tighten the nuts to prevent the spiked feet from changing height, or from rocking side to side. 1 THREADED MOUNTED SOCKET NUT SPIKED FOOT BOTTOM OF ENCLOSURE NUT LOCKED INTO PLACECONNECTIONS Make sure all equipment is turned off before making connections. To connect the loudspeakers to the receiver or amplifier, use two conductor insulated wire. Your Infinity dealer can recommend suitable cables. We recommend 1.3 mm diameter (16 AWG) as a minimum size. If your speakers are more than 10 m (30 feet) from your receiver or amplifier, use larger diameter wire. Interconnects are an important component in an audio system. You may wish to audition and compare the performance of some of the specialty audio interconnects and speaker cable available from your dealer. For each channel, the red terminal on the loudspeaker should be connected to the red or (+) loudspeaker connection terminal on the amplifier (or receiver), and the black terminal on the loudspeaker should be connected to the black or (–) terminal on the amplifier. Connecting the loudspeakers in this manner ensures that they will work in phase; that is, work together rather than in opposition. Connecting the loud- speakers out of phase will not damage them, but will result in less bass and poor imaging. Most two conductor wire is color-coded or has a ridge on one of its insulating jackets, so that you can easily identify which wire is connected to which terminal. When connecting more than one pair of loudspeakers to an amplifier or receiver, consult your dealer or amplifier manufacturer to ensure that the resulting load can be handled safely. BI-WIRING All ALPHA speakers except Alpha 10 and Alpha Center can be bi-wired. Before bi-wiring, AL- WAYS remove the metal bars between the high and low inputs. Bi-wiring will improve resolution and dynamic... »
