Manley Mastering Version Massive Passive Stereo Tube EQ
The Massive Passive is a passive design and not a "true parametric"!
This is the Mastering Version of the Massive Passive with innovative
repeatable, mechanically detented knobs of their own design. Range is
clamped down for focus where mastering engineers live and breathe.
Filters go higher and lower for solving problems in the mastering stage.
A
true parametric implies non-interacting controls. In the Massive
Passive, the "GAIN" and "BANDWIDTH" controls DO interact (on purpose). Manley could not 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.
