■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 listener’s position, speaker placement, subwoofer polarity and other conditions.
