Location

Placing your subwoofer in a corner will produce optimum performance. Experiment with at least two corners and decide which is the best, or you can try the following procedure:

1.Start by placing the subwoofer right on the seat of your favorite couch or easy chair. Take care to position it so it is not likely to fall off. (This method may seem a bit odd, but it is based on principles of acoustic physics.)

2.If you are using the subwoofer as part of a Home Theater system, you can either run a calibration test (noise) signal through the subwoofer, or simply plug the analog outputs of a CD player di- rectly into the subwoofer’s line level inputs. Turn down the subwoofer's volume level before turning on the CD, then play some of your favorite music samples with heavy bass.

3.Walk around the room, listening, and crouch down low in all the positions where you might be able to place the subwoofer. Ideally your ears would be where the sub would be placed. Explain to the family what you are doing, in case they think you've ßipped. Find the place where the subwoofer's bass output sounds the loudest.

4.Shut things down and install the subwoofer in this position. Make sure the control panel is not touch- ing anything, and that it can receive good ventilation.

Although low frequencies are non-di- rectional, factors such as room reßec- tions, standing waves, resonance and ab- sorption will strongly affect your subwoof- er’s performance. Moving the subwoofer from one location to another can have a major effect on the bass response.

The Auto EQ mode will let you adjust for the room effects, but you should Þnd the best location Þrst.

Remember to keep the subwoofer at least two or three feet away from any TV screen, computer, VCR or

magnetic tapes and discs. This will reduce the chance of the magnetic Þelds upsetting the TV screen or erasing your magnetic media.

Using Two Subwoofers

If you wish to use two subwoofers, the sound output will double (an increase of 6 dB). Locate the subwoofers with one in each corner and experiment with the location and phase control to achieve the best bass response.

Always drive each subwoofer through the Left/Mon input even though you are driving one subwoofer with a right chan- nel drive and the other with a left channel drive. If your preampliÞer has a single sub/LFE output, use a Y cable to split it into two outputs.
