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 front speakers by following the procedures described below.

7 3

NORM REV

POWER

OFF

3 8 5 1,6

1Set the VOLUME control to minimum (0).

2Turn on the power of all the other components.

3Make 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.

4Play a source containing low-frequency components and adjust the amplifier’s volume control to the desired listening level.

5Adjust the HIGH CUT control to the position where the desired response can be obtained and press HIGH CUT FILTER button to the ON position.

Normally, set the control to the level a little higher than the front speaker’s rated minimum reproducible frequency*.

*The front speaker’s rated minimum reproducible frequency can be looked up in the speakers’ catalog or owner’s manual.

6Increase the volume gradually to adjust the volume balance between the subwoofer and the front 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.

7Set 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.

8Select “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 listeners enjoy more powerful sound.

MUSIC:

When an ordinary music source is played, the excessive low-frequency components are cut off to make the sound clearer.

Notes

•Once the volume balance between the subwoofer and the front 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 front 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 13.
