■ About the Test Tone
The test tone is produced by the tone generator.
The tone generator produces a narrow band noise centered at a specified
frequency by the band pass filter.
You can change the 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.
