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. 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. Simply insert the Banana Plug connector into the corresponding terminal. How to Connect: Red: positive (+) Black: negative (­) 2 1 3 Unscrew the knob. 5mm (1/4") insulation from the speaker wires. ] Tighten the knob and secure the wire. 6 CONNECTING TO LINE OUTPUT (PIN JACK) TERMINALS OF THE AMPLIFIER · Leave the main speakers connected to the amplifier. · 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.
