OPERATION

1.Set the subwoofer’s Volume control ❹ (Fig. 2) to 12 o’clock.

2.Set the subwoofer’s Low-Frequency Rolloff control ❺ (Fig. 2) to 12 o’clock.

3.Switch the subwoofer’s AC Power switch ❶ (Fig. 2) to the “ON” position.

4.Turn on your entire audio system.

5.Turn the Volume control ❹ (Fig. 2) to its mid position. If no sound emanates from the subwoofer after the auto-sensing system turns it on, check the AC line cord and input cables. Are the connectors on the cables making proper contact? Is the AC plug connected to a “live” receptacle?

6.Once you have confirmed that the subwoofer is active, proceed by playing a CD, record or cassette. Use a selection that has ample bass information.

7.Set the overall volume control of the preamplifier or stereo to a comfortable level. Begin with the subwoofer’s Frequency ❺ (Fig. 2) and Volume ❹ (Fig. 2) control at the 12 o’clock position. Adjust the subwoofer’s Volume control ❹ (Fig. 2) until you obtain a pleasing

blend of bass. Bass response should not overpower the room, but rather be adjusted so there is a harmonious blend across the entire musical range. Many users have a tendency to set the subwoofer volume too loud following the belief that a subwoofer is there to produce lots of bass. This is not entirely true. A subwoofer is there to enhance bass, extending the response of the entire system so the bass can be felt as well as heard. However, overall balance must be maintained; otherwise, the music will not sound natural. An experienced listener will set the volume of the subwoofer so its impact on bass response is always there but is never obtrusive.

8.The Frequency control ❺ (Fig. 2) sets the high-frequency roll-off, adjustable from 50 to 150Hz. Where this control is set depends on the low-frequency capabilities of your satellite speakers, system placement and other factors affecting the mid-bass region. Turn the control UP (clockwise) until you feel there is too much mid-bass information (around 100Hz) then back the control down a bit until that area sounds more natural. If you are pleased with the mid-bass but want to hear more low bass, turn the Frequency control DOWN a bit and the Volume control UP by about the same amount. This will increase low bass while leaving the mid-bass sounding the same as it did before the adjustment. To get a reduction in low bass without changing mid-bass, turn the Frequency control UP and the Volume control DOWN.

9.Room placement of the subwoofer is the most critical aspect of its installation. It will be necessary for you to try various locations in your listening room before you choose the final location. Some possible starting points include: behind the right-channel satellite speaker, along the back wall between the satellites, along a side wall (but not too close to a corner) or behind a couch or a chair.

In general, the closer the subwoofer is to walls and corners, the greater the effect of low- frequency enhancement. Experiment with the Frequency and Volume controls in different locations until you are pleased with the result you obtain from your particular application.
