You must use the R.A.B.O.S. key to adjust these controls. Always adjust both
subwoofers together. Using the adjustment key, 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 p. 16.
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 page 16, “Setting the Subwoofer Test Level.” 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.”
Cue Track 51 of the R.A.B.O.S. Test CD. Press Play
G
. Increase the system volume
until the RSLM indicates -10 dB. Now play Track 52. Adjust both subwoofer gain
controls until -10 dB 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.
