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.

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’s volume control to the desired listening level.

5 Adjust the HIGH CUT control to the position where the desired response can be obtained.

This system is designed so that the optimum tone balance between the subwoofer and the main speakers (NX-430P) is obtained when this control is set at 110 Hz. However, the tone balance may change depending on the room size, the distance from the subwoofer to the main speakers, etc. So, if you prefer, turn the HIGH CUT control and set it to a position where a better tone balance is obtained.

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

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 low- frequency 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 NX-430P 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.
