[. . . ] UC SW-201 Subwoofer System Enceinte a Caisson de Grave OWNER'S MANUAL MODE D'EMPLOI · Explanation of Graphical Symbols CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert you to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert you to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. IMPORTANT Please record the serial number of this system in the space below. Model: Serial No. : The serial number is located on the rear of the main unit. [. . . ] (Refer to page 11 for details on Advanced YAMAHA Active Servo Technology. ) This super-bass sound adds a more realistic, theater-in-the-home effect to your stereo system. This subwoofer can be easily added to your existing audio system by connecting to either the speaker terminals or the line output (pin jack) terminals of the amplifier. The HIGH CUT switch provides you with two positions (HIGH and LOW) to adjust the tone balance between the subwoofer and the main speakers. The AUTO STANDBY switch saves you the trouble of setting the POWER switch to the ON or OFF position. English PLACEMENT Å i Ç ( : subwoofer, : main speaker) One subwoofer will have a good effect on your audio system, however, the use of two subwoofers is recommended to obtain more effect. If using one subwoofer, it is recommended to place it on the outside of either the right or the left main speaker. Å. ) If using two subwoofers, it is recommended to place them on the outside of each main speaker. Ç is also possible, however, if the subwoofer system is placed directly facing the wall, the bass effect may die because the sound from it and the sound reflected by the wall may cancel out each other. To prevent this from happening, face the subwoofer system at an angle as in fig. Å or i. Note There may be a case that you cannot obtain enough superbass sounds from the subwoofer when listening at the middle of the room. This is because "standing waves" have been developed between two parallel walls and they cancel the bass sounds. In such a case, face the subwoofer obliquely to the wall. It also may be necessary to break up the parallel surfaces by placing bookshelves etc. along the walls. E-3 CONNECTIONS Caution: Plug in the subwoofer and other components after all connections are completed. All connections must be correct, that is to say L (left) to L, R (right) to R, "+" to "+" and "­" to "­". If the amplifier has only one set of PRE OUT terminals, do not connect the subwoofer to the PRE OUT terminals. Instead, connect the subwoofer to the speaker output terminals of the amplifier. (Refer to pages 6 and 7. ) When connecting to a monaural line output terminal of the amplifier, connect the L/MONO INPUT2 terminal. When connecting to line output terminals of the amplifier, other speakers should not be connected to the OUTPUT terminals on the rear panel of the subwoofer. If connected, they will not produce sound. E-5 Connecting to speaker output terminals of the amplifier Using one subwoofer If your amplifier has only one set of main speaker output terminals Connect the speaker output terminals of the amplifier to the INPUT1 terminals of the subwoofer, and connect the OUTPUT terminals of the subwoofer to the main speakers.

(Cut the excessive wire if necessary. ) If the connections are faulty, no sound will be heard from the speakers. Make sure that the + and ­ polarity markings of the speaker wires are observed and set correctly. If these wires are reversed, the sound will be unnatural and lack bass.
