THANK YOU!...
for choosing the Manley MASSIVE PASSIVE STEREO TUBE EQUALIZER. This EQ is supposed
to be somewhat different from any EQ you may have used before , as well, this manual may be a bit unusual
in that you may find it worthwhile to read. Even though at first glance the Massive Passive looks fairly
conventional, you should take an hour and read this manual before you jump to conclusions or confusions.
The usual stuff like precautions, hook-up instructions, and operational information is here but also
explanations about how and why this is an unusual animal and hints of how you may find different settings
than you are used to being the key to getting the most out of this box. There is even a little section of EQ
hints or techniques for those who may find that info useful.
As you use this EQ, probably a number of descriptive words may come to you. It has been called "organic",
"natural", "smooth", "liquid", "powerful", "sweet", and "the mother of all EQs". There is no single reason
why it sounds the way it does but more of a synergy of the advantages of passive EQ, the parallel topology,
the tube/transformer amplifiers, the unique shelves and, of course, Manley's construction style and use
of premium components. Like the Manley Variable MU, we have found the Massive Passive can easily
make anything sound better. Perhaps the combination of the "Vari-MU" and the "Passivo" is the killer
combination for music. You may find yourself using it everything. Any gear that you prefer to use on every
sound is a sure sign you bought the right piece.
The Massive Passive is intended as an EQ platform and in the future should offer some interesting custom
options. At some point we expect to offer other EQ cards that can replace some of the passive cards for
particular needs and special applications.
GENERAL NOTES
LOCATION & VENTILATION
The Manley MASSIVE PASSIVE must be installed in a stable location with ample ventilation. It is
recommended, if this unit is rack mounted, that you allow enough clearance on the top of the unit such
that a constant flow of air can move through the ventilation holes. Airflow is primarily through the back
panel vents and out through the top.
You should also not mount the Massive Passive where there is likely to be strong magnetic fields such
as directly over or under power amplifiers or large power consuming devices. The other gear's fuse values
tend to give a hint of whether it draws major power and is likely to create a bigger magnetic field. Magnetic
fields might cause a hum in the EQ and occasionally you may need to experiment with placement in the
rack to eliminate the hum. In most situations it should be quiet and trouble free.
WATER & MOISTURE
As with any electrical equipment, this equipment should not be used near water or moisture.
