About the test tone
The test tone is produced by the tone generator.
The tone generator produces a narrow-band noise centered on a specified frequency by
the band pass filter.
You can change this center frequency from 35 Hz through 250 Hz in one-sixth octave
steps.
You can use the test tone not only for adjusting the subwoofer level, but also for
checking the low-frequency characteristics of your listening room. Low-frequency
sounds are especially affected by the listeners position, speaker placement, subwoofer
polarity and other conditions.
