[. . . ] UCA YST -SW800 Active Servo Processing Subwoofer System Caisson de grave avec asservissement actif OWNER'S MANUAL MODE D'EMPLOI I · 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. [. . . ] 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. Note There may be a case that you cannot obtain enough super-bass sounds from the subwoofer when listening in the center 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. Use the nonskid pads Put the provided nonskid pads at the four corners on the bottom of the subwoofer to prevent the subwoofer from moving by vibrations etc. E-3 CONNECTIONS Caution: Plug in the subwoofer and other audio/video 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 "­". Also refer to the owner's manual for each of your components. The subwoofer can be connected to either the line output (pin jack) terminals or the speaker output terminals of the amplifier. Choose one of the ways shown in this section that is more suitable for your audio system. Also, refer to the owner's manual of your component to be connected to the subwoofer. Basically, connect the subwoofer to the line output (pin jack) terminal(s) of the amplifier. (Refer to pages 4 and 5 for details. ) If your amplifier does not have any line output terminal, connect the subwoofer to the speaker output terminals of the amplifier. (Refer to pages 6 and 7 for details. ) Connecting to line output (pin jack) terminals of the amplifier Connect the main speakers to the speaker output terminals of the amplifier. To connect with a YAMAHA DSP amplifier (or AV receiver), connect the SUBWOOFER (or LOW PASS etc. ) terminal on the rear of the DSP 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 DSP 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.

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 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. [. . . ] Otherwise, set the AUTO STANDBY switch to the "OFF" position. Turn down the volume on the amplifier etc. connected to this unit or cut off the power to other unused equipment. English It is influenced by standing waves. The subwoofer does not turn on automatically. The POWER switch is set to the OFF position. The AUTO STANDBY switch is set to the OFF position. [. . . ]
