If using more than one subwoofer, always adjust both subwoofers together. Adjust the controls as indicated by the Measurement Template. Each value shown in the table is represented by detents in the R.A.B.O.S. controls. Simply count the number of detents necessary, indicated by the results of your R.A.B.O.S. Test.

After performing these adjustments, you may skip forward to the “Final System Balance” section. It is recommended that you perform a second measurement to confirm that the settings are correct.

If you are going to retest the system after EQ adjustments, repeat the “Setting the Subwoofer Test Level” section on page 7.

Retesting the system will go much faster if you use Tracks 27–50. These tracks contain all the same test tones you just used. However, each tone plays for only a few seconds and there is no frequency announcement. If you are uncomfortable operating at this pace, you may, of course, perform measure- ments with the original test tracks.

Your first interpretation of the data and choice of settings may not be optimum. You can repeat the test-adjust-test cycle as often as needed to get the desired results. To do this, return to “Setting the Subwoofer Test Level”on page 7. You may prefer to retest using the same template. Doing so makes it easy to evaluate the improvement.

When you are satisfied with the results, go to “Final System Balance.”

Final System Balance

Cue Track 51 of the R.A.B.O.S. Test CD. Press Play ›. Increase the system volume until the RSLM indicates –10dB. Now play Track 52. Adjust the subwoofer gain control until –10dB

is indicated on the RSLM. Of course, you may fine-tune the subwoofer gain control to your listening preference.

This concludes the R.A.B.O.S. process. It is recommended that you remove the battery from the RSLM. Store the Test CD, Width Selector, Adjustment Key and the RSLM together.
