that will be affected by the amplitude setting. For the K2500, the width is defined by imagining
an amplitude curve with a level (in dB) of -infinity (minus infinity) at the center frequency, then
measuring the distance (in octaves) between the points on the curve where the amplitude is
attenuated by 3dB. See the diagram below.
