The gain at the center frequency is 0 dB. Small values for width (a narrow bandpass) may
produce a very quiet signal unless the center frequency matches the frequency of a strong sine
wave partial. Wide bandpasses may result in a quiet signal if theyÕre centered in a region of the
sound where the partials are weak. You can easily boost these quiet signals with the parameters
on the F4 AMP page.
