English 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. Front panel SUBWOOFER SYSTEM YST-SW015 STANDBY/ON B.A.S.S. HIGH CUT50-150Hz VOLUME 0-10 SUBWOOFER SYSTEM YST-SW015 STANDBY/ON B.A.S.S.

Normally, set the control to 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. 8 Select "MOVIE" or "MUSIC" according to the played source. MOVIE: When a movie type source is played, the lowfrequency effects are enhanced to allow the listener enjoy more powerful sound. (The sound will be thicker and deeper.) MUSIC: When an ordinary music source is played, the excessive low-frequency components are cut off to make the sound clearer. (The sound will be lighter and reproduces the melody line more clearly.) • 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 the next page.
