The Bass MuRF’s FILTERS
The Bass MuRF’s seven resonant filters have fixed center
frequencies and a shelving(lowpass) filter that has a fixed cutoff
frequency. These frequencies are shown on the legend underneath
the filters’ sliders. Their frequencies are: 110 Hz(shelving filter),
160 Hz, 240 Hz, 350 Hz, 525 Hz, 775 Hz, 1.2K and 1.8K.

Each filter has a slider that adjusts the gain of that filter. In this
respect, the Bass MuRF resembles a graphic equalizer. When a
filter’s slider is all the way down, the gain for that filter is zero,
and the filter’s output is zero. When the slider is all the way up,
the filter’s output is maximized. The resemblance to a graphic EQ
ends there. The Bass MuRF’s filters have a characteristic that sets
them far apart from a graphic equalizer. A graphic equalizer will
theoretically not color the signal at all when all the sliders are set
to the same level. The Bass MuRF’s resonant filters and shelving
filter on the other hand color the signal a great deal, adding warm
analog resonances at pleasing intervals through out the frequency
spectrum of a bass instrument. We’ll now show how the Bass
MuRF’s filters affect your MF-105B frequency response. We will
always start with this ‘basic’ panel setup, which is:
