[. . . ] UB YST-SW515 Subwoofer System OWNER'S MANUAL IMPORTANT SAFETY INSTRUCTIONS 1 Read these instructions. 7 Do not block any ventilation openings. Install in accordance with the manufacturer's instructions. Explanation of Graphical Symbols 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. 8 Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. 9 Do not defeat the safety purpose of the polarized or grounding-type plug. [. . . ] 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. Use the non-skid pads C Put the provided non-skid pads at the four corners on the bottom of the subwoofer to prevent the subwoofer from moving by vibrations etc. ( : subwoofer, : front speaker) 3 CONNECTIONS Choose one of the following two connecting methods that is more suitable for your audio system. Choose 1 Choose 2 (pages 4-5) if your amplifier has line output (pin jack) terminal(s) (pages 6-7) if your amplifier has no line output (pin jack) terminal Caution: Unplug the subwoofer and other audio/video components before making connections. Notes · All connections must be correct, that is to say L (left) to L, R (right) to R, "+" to "+" and "­" to "­". Also, refer to the owner's manual of your component to be connected to the subwoofer. · After all connections are completed, plug in the subwoofer and other audio/video components. 1 Connecting to line output (pin jack) terminals of the amplifier · To connect with an amplifier (or AV receiver), connect the SUBWOOFER (or LOW PASS etc. ) terminal on the rear of the amplifier (or AV receiver) to the L /MONO INPUT2 terminal of the subwoofer. · When connecting the subwoofer to the SPLIT SUBWOOFER terminals on the rear of the amplifier, be sure to connect the L /MONO INPUT2 terminal to the "L" side and the R INPUT2 terminal to the "R" side of the SPLIT SUBWOOFER terminals. Notes · Some amplifiers have line output terminals labeled PRE OUT. When you connect the subwoofer to the PRE OUT terminals of the amplifier, make sure that the amplifier has at least two sets of PRE OUT terminals. 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 6-7. ) · 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. 4 CONNECTIONS Using one subwoofer Subwoofer Mono pin cable (not included) Audio pin cable (not included) To AC outlet Amplifier Using two subwoofers Mono pin cable(not included) Subwoofer Subwoofer Mono pin cable (not included) Amplifier To AC outlet To AC outlet 5 CONNECTIONS 2 Connecting to speaker output terminals of the amplifier Select this method if your amplifier has no line output (pin jack) terminal. If your amplifier has two sets of front speaker output terminals and both terminals can output sound signals simultaneously. · Connect one set of front speaker output terminals of the amplifier to the INPUT1 terminals of the subwoofer, and connect the other set of front speaker output terminals of the amplifier to the front speakers. · Set the amplifier so that both sets of front speaker output terminals output sound signals simultaneously. Note · If your amplifier has only one set of front speaker output terminals, see page 7. Using one subwoofer (with speaker cables) Subwoofer Left front speaker Right front speaker To AC outlet Amplifier Speaker output terminals Using two subwoofers (with speaker cables) Speaker output terminals Left front speaker Amplifier Right front speaker Subwoofer Subwoofer To AC outlet To AC outlet 6 CONNECTIONS If your amplifier has only one set of front 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 front speakers. Using one subwoofer (with speaker cables) Left front speaker Right front speaker Subwoofer Amplifier To AC outlet Speaker output terminals Using two subwoofers (with speaker cables) Left front speaker Right front speaker Subwoofer Subwoofer Amplifier To AC outlet Speaker output terminals To AC outlet 7 CONNECTIONS Connecting to the INPUT1/OUTPUT terminals of the subwoofer For connection, keep the speaker cables as short as possible. Do not bundle or roll up the excess part of the cables. If the connections are faulty, no sound will be heard from the subwoofer or the speakers, or both of them. Make sure that the + and ­ polarity markings of the speaker cables are observed and set correctly. If these cables are reversed, the sound will be unnatural and lack bass. Caution Do not let the bare speaker wires touch each other, because this could damage the subwoofer or the amplifier, or both of them. U. S. A. , Canada and Australia models only Banana Plug conection are also possible. 1 2 Tighten the terminal knob. Simply insert the banana plug into the terminal 1 2 Before connecting Plug in the subwoofer to the AC outlet After all connections are completed, plug in the subwoofer and other audio/video components to the AC outlet. Remove the insulation coating at the extremity of each speaker cable by twisting the coating off. Good 10mm (3/8") No Good How to connect: 1 2 3 4 Loosen the terminal's knob, as shown in the figure. [. . . ] Set the AUTO STANDBY switch to the "HIGH" or "LOW" position. Set the AUTO STANDBY switch to the "HIGH" position. Move the subwoofer farther away from such appliances and/or reposition the connected speaker cables. Otherwise, set the AUTO STANDBY switch to the "OFF" position. [. . . ]
