the main speakers by following the procedures described below.

1 Set the volume level on the amplifier to minimum, and turn on the amplifier and other components.

2 Turn the VOLUME control to set the control to minimum (0).

3 Make sure that the POWER switch on the rear panel 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’s volume control to the desired listening level.

5 Turn the HIGH CUT control (or press the

HIGH CUT UP/DOWN buttons on the remote control) to set the control to the position where the desired response can be obtained.

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 Press the PHASE button to select the regular or reverse mode which gives you the better bass sound.

Normally, select the reverse mode (so that the PHASE indicator on the front panel lights up in green). If the desired response cannot be obtained, select the regular mode (so that the PHASE indicator lights up in red).

8 Select “MOVIE” or “MUSIC” according to the played source.

MOVIE (when the MUSIC/MOVIE indicator on the front panel lights up in green):

When a movie type source is played, the low-frequency effects are enhanced to allow the listener enjoy more powerful sound. (The sound will be thicker and deeper.)

MUSIC (when the MUSIC/MOVIE indicator on the front panel lights up in red):

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 button, refer to “Frequency characteristics” on page 17.
