[. . . ] Since hearing damage from loud sounds is often undetectable until it is too late, YAMAHA and the Electronic Industries Association's Consumer Electronics Group recommend you to avoid prolonged exposure from excessive volume levels. SUPPLIED ACCESSORIES After unpacking, check that the following parts are contained. Remote Control Transmitter Batteries (size AA, R6, UM-3) Speaker Cords POWER ON/OFF OUTPUT HIGH-CUT UP VOLUME DOWN 3 FEATURES · This subwoofer system employs YAMAHA Active Servo Technology which YAMAHA developed for reproducing higher quality super-bass sound. (Refer to page 13 for details on Active Servo Technology. ) This unit does not only enhance bass frequency response of sound output in your audio system, but, by reproducing the bass frequencies, the subwoofer permits your existing amplifier and speakers to operate under less strenuous conditions, improving overall system performance. · · This unit can be added easily to your existing audio system by connecting to either the speaker terminals or the line output (pin jack) terminals of the amplifier. For the effective use of this unit, this unit's super-bass sound must be matched to the sounds on your main speakers. Therefore, this unit employs the continuously variable high frequency cut-off point (HIGH-CUT) control. Moreover, the PHASE switch allows you to select better sound quality according to the listening condition. PLACEMENT A B C If using one subwoofer system, it is recommended to place it on the outside of either the right or the left main speaker. A . ) If using two systems, it is recommended to place them on the outside of each main speaker. C 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 will collide. To prevent this, face the subwoofer system obliquely to the wall as shown in fig. A or B. One subwoofer system will have a good effect on your audio system, however, the use of two subwoofer systems is recommended to obtain more presence. Note There may be a case that you cannot obtain enough superbass sounds from this unit when listening at the middle of the room. This is because the "standing waves" occur between two parallel walls and the bass sounds are canceled. In such a case, face the unit obliquely to the wall. It also may be necessary to break up the parallel surfaces by placing bookshelves etc. along the walls. 4 CONNECTIONS · Before attempting to make any connections to or from this unit, be sure to first switch OFF the power to this unit and to any other components to which connections are being made. · When making connections between this unit and other components, be sure all connections are made correctly and consistently, that is to say L (left) to L, R (right) to R, "+" to "+" and "­" to "­". · This unit can be connected to either the speaker terminals or the line output (pin jack) terminals of the amplifier. Choose one of the ways shown below according to your audio system. Also, refer to the owner's manual for each component to be connected to this unit. CONNECTING TO SPEAKER TERMINALS OF THE AMPLIFIER · Disconnect your main speakers from the amplifier and connect them to this unit. · Line output terminals may be labeled PRE OUT, REC OUT or SUBWOOFER OUT. * For PRE OUT terminal connection, the amplifier must possess at least two sets of PRE OUT terminals. With some amplifiers with only one set of PRE OUT terminals, connection can result in no sound from the main left and right speakers. In this case, select an alternative method of connection.

[. . . ] Setting of the PHASE switch is not proper. A source sound with few bass frequencies is played. The remote control transmitter does not work. The distance or range within which the remote control transmitter can be used decreases. [. . . ]
