Manley Massive Passive Stereo EQ - Mastering Version

A versatile EQ with the warmth of tubes and filters tailored for mastering!




The mastering version of the Manley Massive
Passive Stereo EQ provides precisely repeatable settings. Manley came up
with a clever way to pull it off without breaking your bank account:
mechanically detented knobs for the Gain and Bandwidth controls to
ensure repeatability—which is what everyone wanted, but without the
incredible cost and space problems that tons of Grayhill switches would
have caused.

Some notes pertinent to the Manley Mastering Stereo EQ:

The
Manley 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).
It is not possible to 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 12dB. 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 a repeatable 16 steps.
The FREQUENCY select is already detented and always has been a Grayhill
switch. It also interacts in shelf mode.

On a similar note, the
Manley Massive Passive is a "parallel design" and not the conventional
"series design". This means the bands interact with each other too. It
is possible, to set a band to boost 20 dB but if another band is
boosting near or at that frequency, very little will happen. On a
conventional EQ the two bands "add" and you would be boosting 40 dB into
clipping. Because the bands interact, predictable step sizes are
unrealistic, however, with the Mastering Version, you will be able to
repeat settings (if you log them of course). The price paid for
interacting bands, is a better sounding EQ and bizarre looking settings
(on purpose).

Unlike virtually every other EQ, the Massive
Passive Equalizer allows much more EQ without sounding "processed".
Where 5- or 6dB is about all one could attempt with other EQs in
mastering, the Massivo amazes engineers with how much EQ they can do and
get more natural results at the same time. Manley could have squeezed
11-position Grayhill switches in the modules if they had wanted 1/2dB
steps, but then the maximum range would have become only 5-1/2dB. The
minimum range would then become about 1-1/2dB with approximately 0.2dB
steps. This approach would have essentially thrown away most of the
useful range the unit is capable of. Going with these special
mechanically detented knobs, which use the same pots underneath that the
normal Massivo uses, you get nearly all the range of the normal
version, but with the added benefit of repeatability made possible by
the detents.

With mastering engineers in mind, Manley has
custom-tailored the FILTERS in this Mastering Version, moving them lower
and higher than the normal version. This was done specifically for
mastering purposes. If you're looking for drastic effects (like
telephone sounds) then get the normal version. These filters are
specifically geared for mastering engineers.

Additionally, the
Master Gain Trim controls in the Manley Mastering EQ are true
11-position 1/2dB stepped Grayhill switches, set up for a range between
-2.5 to +2.5 dBof master gain trim. This allows more confidence in
left/right matching and calibration.

The Filters – 5 frequencies Hi Pass and bypass, PLUS 5 frequencies Lo Pass with bypass.

High Pass Filters = 12, 16, 23, 30, 39Hz, OFF
Low Pass Filters = 15K, 20K, 27K, 40K, 52KHz, OFF

The
filters are somewhat better tuned specifically for mastering. (They are
flatter until the knee). As with the standard version the slopes are
typically 18dB per octave, on these mastering filters except for the
highest (52K) at 30 dB/octave.

Parametric Frequencies (same as normal Massivo):
LOW - 22, 33, 47, 68, 100, 150, 220, 330, 470, 680, 1K
LM - 82, 120, 180, 270, 390, 560, 820, 1K2, 1K8, 2K7, 3K9
HM - 220, 330, 470, 680, 1K, 1K5, 2K2, 3K3, 4K7, 6K8, 10K
HI - 560, 820, 1K2, 1K8, 2K7, 3K9, 5K6, 8K2, 12K, 18K, 27K
