■ 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.
