Third, refine the Band Gain controls for optimum suppression.
Set all six Band Gain controls to 0dB. Now increase and decrease the gain in each band
separately while listening to the effect that each has on the noise. This will identify the bands
that contain the majority of the noise. (Do not be alarmed if all six bands contain significant
noise. This is not unusual.)
Let’s assume that the greatest improvement occurs when you reduce the gain in bands 3 and 4.
This suggests that the noise is concentrated in an approximate range of 200Hz to 1kHz. You
should now find the optimum positions for all six faders. The greatest cuts will lie in bands 3 and
4, whereas bands 1, 2, 5 and 6 should remain as close to 0dB as possible to ensure that
minimal signal damage occurs in the bands that do not contain much noise.
The final configuration might look like this:
