format_quote The Massive Passive is a passive design and not a "true parametric". A true parametric implies non-interacting controls. In the Massive Passive, the "GAIN" and "BANDWIDTH" controls DO interact (on purpose). We cannot create a "GAIN" switch that is set up for "consistent" 1/2 dB steps. When you change the "BANDWIDTH" the step size must and will change. On the regular version, you get a full 20dB boost or cut only when: the bandwidth is fully clockwise (narrow) in bell mode or fully counter-clockwise in shelf mode. Here on the Mastering Version, this maximum boost or cut is 11dB. Conversely at the widest bell, the maximum boost or cut is 6dB and the narrowest shelf maxes out at 12 dB. A similar situation is also true for the bandwidth detents. So in this new Mastering Version, do not expect a certain dB change per step as it will vary according to where the bandwidth is set. But whatever the step sizes are, they will be repeatably 16 steps. The FREQUENCY select is already detented as it is and always has been a Grayhill switch. It also interacts in shelf mode.
