PLACEMENT A CONTROLS AND THEIR FUNCTIONS Front Rear B ( : subwoofer, : front speaker) The subwoofer will have a good effect on your audio system. Using the subwoofer, it is recommended to place it on the outside of either the right or the left front speaker. (See fig. A .) The placement shown in fig. B is also possible, however, if the subwoofer system is placed directly facing the wall, the bass effect may suffer due to cancellation of direct and reflected sounds. To prevent this from happening, place the subwoofer system at an angle, as in fig. A . 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 developed between two parallel walls and cancel the bass sounds. In such a case, place the subwoofer at an oblique angle to the wall. It also may be necessary to break up the parallel surfaces by placing bookshelves, etc. along the walls. Power indicator Lights up Green when the POWER switch is turned ON; turns off when the POWER switch is turned OFF. INPUT (FROM AMPLIFIER) terminal Used to connect the subwoofer with the subwoofer terminal of the amplifier. (Refer to "CONNECTIONS" for details.) VOLUME control Adjusts the volume level. Turn the control clockwise to increase the volume, and counterclockwise to decrease the volume. POWER switch Press this switch to the ON position to turn on the power to the subwoofer. Press this switch again to set it to the OFF position to turn off the power of the subwoofer. VOLTAGE SELECTOR switch (Asia and General models only) If the preset setting of the switch is incorrect, set the switch to the proper voltage (110-120/220-240V) of your area. Consult your dealer if you are unsure of the correct setting. WARNING Be sure to unplug the subwoofer before setting the VOLTAGE SELECTOR switch correctly. 3 En English
