Description of controls is as follows:

Notch Freq (1-16): Specifies frequency in Hertz which is to be removed from the input audio by

each of the 16 notches. Minimum Notch Freq is 1 Hz, while maximum Notch

Freq depends upon the System Bandwidth setting. Set Notch Freq to Out

(scroll box in full left position) if the notch is not desired. Notch Freq is

adjustable in 1 Hz steps.

Notch Width Specifies width in Hertz for each of the 16

(1-16): notches. Minimum and maximum Notch Widths and adjustment resolution

depend upon the System Bandwidth setting.

Build Button: Causes the FIR filter coefficients for the Multiple Notch filter to be calculated

and loaded into the external processor for implementation. While this is

occurring, an "hourglass" mouse cursor will appear.

NOTE: You must click the Build button after any Notch Freq or Notch Width

is changed in order for the change to take effect. You must also click the Build

button after any change in System Bandwidth or Input Mode in order to

rebuild the filter.
