ENGLISH Important! Introduction The Infinity Alpha Junior Subwoofer has been designed to enhance the bass fre- quencies of any audio system. This subwoofer may be used with speakers of any size. Obviously, the greatest bass enhancement will be achieved when the subwoofer is connected with speakers that do not have the capability to create deep bass. This subwoofer may be used individually, or combined with another Alpha Junior subwoofer for even more impressive reproduction of bass frequencies (i.e., one subwoofer near the satellite speakers and a second subwoofer behind the primary listening area, or both subwoofers up front). The Alpha Junior Subwoofer is a self- powered system utilizing a solid-state, low-frequency amplifier driving a specially designed woofer mounted within a structurally rigid, tuned-port enclosure. Unpacking the Subwoofer Check your subwoofer carefully. If it has been damaged in transit, report the damage immediately by calling your dealer and/or the trucking firm that delivered it. To prevent fire or shock hazard, DO NOT EXPOSE THIS SUBWOOFER SYSTEM TO RAIN OR EXCESSIVE MOISTURE. To avoid electric shock, DO NOT OPEN THE SUBWOOFER! There are no user serviceable parts inside. Observe all warnings and cautions. About this product... Important ! Volume control... A Few Suggestions We recommend that you not operate your speakers or subwoofer with the bass, treble and loudness controls set to full boost. This will place undue strain on your electronics and speakers and could damage them. The volume control setting on your preamplifier or stereo receiver is not a specific indication of the overall loudness level of the speakers. The only important consideration is the loudness level at which the system can be played regardless of where the volume control is set. Always turn down the volume control setting on your preamplifier or stereo when changing a cassette or CD, or switching inputs to AM or FM operation. Excessively loud transients (clicks or popping sounds) can damage the satellite speakers and possibly the subwoofer. Whenever changing cables, pulling plugs, etc., ALWAYS TURN OFF ALL EQUIPMENT, including the subwoofer. This prevents transients from entering the speakers and prevents electrical energy from reaching you. Keep all connections out of the reach of children. 2Alpha Junior Subwoofer -“ Owners Manual

ENGLISH Alpha Junior Subwoofer -“ Owners Manual 3 Position within a room will strongly influence performance... Positioning Since the installation of a subwoofer is somewhat more complicated than installing full- range speakers, it is essential you read this section very carefully prior to connecting the subwoofer to your system. Should you have questions relating to your installation, it is advisable to call your Infinity dealer for advice. The performance of the subwoofer is directly related to its placement in the listening room and how you align the subwoofer with its satellite speakers. Setting the volume of the subwoofer in relationship to the left and right speakers is also of critical importance because it is essential that the subwoofer integrates smoothly with the entire system. Setting the subwoofers volume level too high will result in an over- powering, boomy bass. Setting the volume level too low will negate the effect of the subwoofer. The metal plate acts as the heat sink for the subwoofers internal amplifier. Do not place pillows or other objects against it. We recommend placing the subwoofer at least 2 to 3 feet away from a television or a computers disc-drive system to prevent smearing the colors of the TV picture or erasing of the magnetic drive. Here are several additional facts on installation that may prove useful. It is generally believed by most audio authorities that low frequencies (below 125Hz) are non- directional and, therefore, placement of a subwoofer within any listening room is not critical. While in theory it is true that the larger wavelengths of extremely low frequencies are basically non-directional, the fact is that when installing a subwoofer within the limited confines of a room, reflections, standing waves and absorption generated within the room will strongly influence the performance of any subwoofer system. As a result, specific location of the subwoofer becomes important, and we strongly recommend that you experiment with placement before choosing a final location. Placement will depend upon your room and the amount and quality of bass required (for example, whether or not your room permits placement of the subwoofer near either satellite). Never place the port too close to a wall or piece of furniture as this will prevent the port from operating properly. Since the port is an integral part of the subwoofers design, it should always be permitted free access to the listening room without obstruction to the sound emerging from it. Careful experimentation will enable you to determine the best position for the subwoofer (see useful hints, next page).
