For example, the unit should not be situated on a bed, sofa, rug, or similar surface, that may block the ventilation openings; or placed in a built-in installation, such as a bookcase or cabinet that may impede the flow of air through the ventilation openings. [. . . ] Voltage Selector (General Model only) The voltage selector on the rear panel of this unit must be set for your local main voltage BEFORE plugging into the AC main supply. Voltages are AC 110/120/220/240V, 50/60 Hz. 4 English FEATURES · This subwoofer system employs YAMAHA Active Servo Technology which YAMAHA developed for reproducing higher quality super-bass sound. (Refer to page 15 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. · 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 which is suitable for your audio system. Also, refer to the owner's manual for each component to be connected to this unit.

If the connections are faulty, no sound will be heard from the speakers. Make sure that the polarity of the speaker wires is correct, that is, + and ­ markings are observed. If these wires are reversed, the sound will be unnatural and will lack bass. Do not let the bare speaker wires touch each other and do not let them touch the metal parts of this unit as this could damage this unit, your amplifier and/or speakers. * Banana Plug connections are also possible (except for U. K. Simply insert the Banana Plug connector into the corresponding terminal. How to Connect: Red: positive (+) Black: negative (­) 2 1 3 1 Unscrew the knob. 2 Insert the bare wire. [Remove approx. 5mm (1/4") insulation from the speaker wires. ] 3 Tighten the knob and secure the wire. 7 CONNECTING TO LINE OUTPUT (PIN JACK) TERMINALS OF THE AMPLIFIER · Leave the main speakers connected to the amplifier. 1 CONNECTING TO PRE OUT OR SUBWOOFER OUT TERMINAL(S) · Amplifier line output terminals are generally labeled PRE 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 the method of connecting to the speaker terminals. · To connect with a YAMAHA DSP amplifier, connect the LOW PASS (or SUBWOOFER etc. ) terminal on the rear of the DSP amplifier to either the left (L) or right (R) INPUT 2 terminal.
