The BOOST/CUT control of the MF band realizes maximum
boost of 15dB and maximum cut of -36dB.This response is called
‘non-reciprocal response’.Due to the enormous headroom of this
filter design the sound of the MF band is even more open and
transparent and almost unlimited in dynamic response.
All B/C controls feature stepped potentiometers with 31
detends which allow adjustments in steps of 0.5dB. Due to the
non-reciprocal response of the MF band the cut values are adju-
stable in 1dB steps.
Setting up procedure: When trying to locate the precise
frequency range requiring adjustment, set the B/C control fully
clockwise to provide maximum boost. By sweeping through the
frequency ranges, it should be easy to locate the precise
frequency range that needs cutting or boosting.
