Chapter 30: Manley Massive Passive EQ
Shelf/Bell
The Shelf/Bell toggle switch defines the shape of the filter band. A
unique aspect of this control is that unlike other EQs where only the
edge frequencies offer a shelving mode, with Massive Passive all
bands can be used in either mode for expanded sonic possibilities.
Note:
) affects the slope of the band filters
in both Shelf and Bell modes.
Shelf
The two lowest (leftmost) bands can each be in Low Shelf mode; the two high-
est (rightmost) bands can each be in High Shelf mode. Shelf slopes generally
boost or cut towards the highs or lows (thus the high shelves and low shelves).
The two middle shelves are almost the same as the outer ones but just have
other (interleaved) frequency choices.
Bell
Bell curves focus their boost and cut at a given frequency (the
) and the further away the signal is from that frequency, the less
boost or cut is applied.
Band Gain
This control determines the amount of EQ gain to be applied to the
band. The range is from zero gain (flat) at the fully counter-clock-
wise position, to the maximum value at the fully clockwise posi-
tion. Whether the gain is applied as a boost or cut is defined by
).
The range for the standard version is continuously variable at up to ±20 dB;
the range for the Mastering version is up to ±11 dB in 16 steps (in both ver-
sions the maximum value depends on the Bandwidth control).
Important:
When Gain for the band is set to zero, the other band controls
have no effect.
Unlike most EQs, this control is not flat at the center position with the gain cut
or boosted by moving the control to left or right of center. This design allows
the band gain to operate at twice the knob resolution as that of a “conven-
tional” dual-purposed control, as well as facilitating a quicker and more ac-
curate return to zero.
