• Specifications are subject to change without notice due toproduct improvements. 2-SW015(E) (03.1.19)a 03.2.28, 7:16 PM2English E-3 PLACEMENT It is recommended to place the subwoofer on the outside ofeither the right or the left main speaker. (See fig. Å .) Theplacement shown in fig. ı is also possible, however, if thesubwoofer system is placed directly facing the wall, thebass effect may die because the sound from it and thesound reflected by the wall may cancel out each other. Toprevent this from happening, face the subwoofer system atan angle as shown in fig. Å. 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 cancelthe bass sounds.In such a case, face the subwoofer obliquely to the wall. Italso may be necessary to break up the parallel surfaces byplacing bookshelves etc. along the walls. ( : subwoofer, : main speaker)Use the non-skid padsPut the provided non-skid pads at the four corners on thebottom of the subwoofer to prevent the subwoofer frommoving by vibrations etc.

(Refer to “CONNECTIONS” for details.) 9 AUTO STANDBY (HIGH/LOW/OFF) switch This switch is originally set to the OFF position. Bysetting this switch to the HIGH or LOW position, thesubwoofer’s automatic power-switching functionoperates as described below. If you do not need thisfunction, leave this switch in the OFF position.* Make sure to change the setting of this switch onlywhen the subwoofer is set in the standby mode bypressing the STANDBY/ON (

0 PHASE switch Normally this switch is to be set to the REV (reverse)position. However, according to the listening conditionor your preference, there may be a case when bettersound quality is obtained by setting this switch to theNORM (normal) position. Select the better position bymonitoring the sound.

AUTOMATIC POWER-SWITCHING FUNCTION

IIf the source being played is stopped and the input signal iscut off for 7 to 8 minutes, the subwoofer automaticallyswitches to the standby mode. (When the subwooferswitches to the standby mode by the automatic power-switching function, the power indicator lights up in red.)When you play a source again, the power of the subwooferturns on automatically by sensing audio signals input to thesubwoofer.This function operates by sensing a certain level of lowfrequency input signal. Usually set the AUTO STANDBYswitch to the LOW position. However, if this function doesnot operate smoothly, set the switch to the HIGH position. Inthe HIGH position, the power will turn on even with a lowlevel of input signal. But please be aware that the subwoofermay not switch to the standby mode when there is anextremely low input signal.* The power might turn on unexpectedly by sensing noisefrom other appliances. If that occurs, set the AUTOSTANDBY switch to the OFF position and use theSTANDBY/ON button to switch the power between onand in the standby mode manually.* This function detects the low-frequency componentsbelow 200 Hz of the input signals (i.e., the explosion inthe action movie, the sound of the bass guitar or the bassdrum, etc.).* The minutes required to switch the subwoofer to thestandby mode might change by sensing noise from otherappliances.This function is available only when the power of thesubwoofer is on (by pressing the STANDBY/ON button). 2-SW015(E) (03.1.19)a 03.2.28, 7:17 PM6English E-7 1 Set the VOLUME control to minimum (0). 2 Turn on the power of all the other components. 3 Make sure that the POWER switch is set to the ON position, then press the STANDBY/ON button to turn on the subwoofer.* The Power indicator lights up in green. 4 Play a source containing low-frequency components and adjust the amplifier’svolume control to the desired listening level. 5 Adjust the HIGH CUT control to the position where the desired response can beobtained.Normally, set the control to the main speaker’s ratedminimum reproducible frequency*.* The main speaker’s rated minimum reproduciblefrequency can be looked up in the speakers’ catalogor owner’s manual. 6 Increase the volume gradually to adjust the volume balance between the subwoofer andthe main speakers.Normally, set the control to the level where you canobtain a little more bass effect than when the subwooferis not used. If the desired response cannot be obtained,adjust the HIGH CUT control and the VOLUME controlagain.Before using the subwoofer, adjust the subwoofer to obtain the optimum volume and tone balance between the subwoofer andthe main speakers by following the procedures described below. 7 Set the PHASE switch to the position which gives you the better bass sound.Normally, set the switch to the REV (reverse) position. Ifthe desired response cannot be obtained, set the switchto the NORM (normal) position. 8 Select “MOVIE” or “MUSIC” according to the played source.MOVIE: When a movie type source is played, the low-frequency effects are enhanced to allow the listenerenjoy more powerful sound. (The sound will be thickerand deeper.)MUSIC: When an ordinary music source is played, theexcessive low-frequency components are cut off tomake the sound clearer. (The sound will be lighter andreproduces the melody line more clearly.)• Once the volume balance between the subwoofer andthe main speakers is adjusted, you can adjust thevolume of your whole sound system by using theamplifier’s volume control.However, if you change the main speakers to others,you must make this adjustment again.• For adjusting the VOLUME control, the HIGH CUTcontrol and the PHASE switch, refer to “Frequencycharacteristics” on the next page.
