Introduction - Manley TNT Owner's Manual

INTRODUCTION

THANK YOU !
For choosing the Manley TNT Microphone Preamplifier. The name of this mic preamplifier "TNT" is
a reference to the two different channels, one that is Tube and the other No Tube. We see people today
hungry for a variety of preamps as a means of getting a variety of sounds and tones from the start. Of
course, mic selection and mic position can produce a wider variety of colors, but once that is locked
in, the preamp choice can be a significant factor in some sessions and that subtle difference in others.
The designer considers the reference to TNT (the explosive) might be a bit apropos too. Both share
a reputation as a relatively powerful and particularly useful tool for the 'difficult' tasks while being
relatively safe (well, much safer and more stable than Nitro-Glycerine, its main component). Manley
would like to thank Steve Pogact for suggesting the name.
Most mic preamps are stereo, which is fine when one needs to record true stereo with matched mics
(few are), but the most common situations where one can compare and choose a particular preamp,
are the often the more relaxed overdubs. These are typically single miked or multi-miked where each
mic might be a different type and different distance from the source. So the TNT might be the ideal
cost-effective solution for these situations – maximum choices & minimum cost and rack space and
where you need to know you are using the one of the best.
Some people use the TNT simply because it offers two different sounds and is different from their
other preamps. Some people choose it because each channel may be a contender for the highest
caliber preamp in either the "tube category" or "solid-state category" and they demand the best. And
some users just like the unique controls and features. Of course, given a variety of sounds and fea-
tures, different people will gravitate to one side or the other and one feature or another. This is to be
expected and probably encouraged, however let us emphasize that we encourage you to dig in, use it
to its fullest and form you own opinions and methods that work for you.
GENERAL NOTES
LOCATION & VENTILATION
The Manley TNT 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 TNT 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. Magnet-
ic fields might cause a hum in the preamp and occasionally you may need to experiment with place-
ment 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.
