ADJUSTING THE SUBWOOFER BEFORE USE Before using the subwoofer, adjust the subwoofer to obtain the optimum volume and tone balance between the subwoofer and the main speakers by following the procedures described below. Subwoofer rear panel PHASE OUTPUT TO SPEAKERS INPUT 1 FROM AMPLIFIER INPUT 2 AUTO STANDBY PHASE /MONO OFF HIGH LOW NORM REV POWER ON OFF NORM REV 3 (U.S.A. model) 7 SUBWOOFER SYSTEM YST-RSW300 STANDBY/ON HIGH CUT VOLUME 40Hz 140Hz 0 10 3 5,6 1,6 Subwoofer front panel 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 on the rear panel is set to the ON position, then press the STANDBY/ON switch on the front panel to turn on the subwoofer. * The status indicator lights up in green. 4 Play a source containing low-frequency signals and adjust the amplifier's volume control to the desired listening level. 5 Adjust the HIGH CUT control to the position where the desired response can be obtained. Normally, set the control to the level a little higher than the main speaker's rated minimum reproducible frequency*. * The main speaker's rated minimum reproducible frequency can be looked up in the speakers' catalog or owner's manual. 6 Increase the volume gradually to adjust the volume balance between the subwoofer and the main speakers. Normally, set the control to the level where you can obtain a little more bass effect than when the subwoofer is not used. If the desired response cannot be obtained, adjust the HIGH CUT control and the VOLUME control again. 7 Set the PHASE switch to the position which gives you the better bass sound. Normally, set the switch to the REV (reverse) position. If the desired response cannot be obtained, set the switch to the NORM (normal) position. Notes • Once the volume balance between the subwoofer and the main speakers is adjusted, you can adjust the volume of your whole sound system by using the amplifier'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 CUT control and the PHASE switch, refer to "FREQUENCY CHARACTERISTICS" on page 14. 12 En
