Owners Manual

INTRODUCTION
!
THANK YOU!...
for choosing the Manley Laboratories Stereo Variable-MU Limiter Compressor . The
heart of this limiter is the variable gain vacuum tube. In tube-talk MU refers to gain
and only a few types of tubes were ever designed for variable-mu operation. This
limiting circuitry was designed by David Manley over thirty years ago. Our current
version of this unique piece combines that classic sound with the precise cleanliness
of modern componentry. The circuit is entirely differential which tends to cancel
distortion and hum. It can handle a widely varying range of input signals in a rapid-
acting manner without introducing audible coloration common in many limiters. The
Attack and Recovery (Release) times have been carefully chosen for todays
applications. These properties make this a superb compressor for both individual
tracks, mixes and final mastering.
GENERAL NOTES
LOCATION & VENTILATION
The Limiter Compressor Amplifier 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 and bottom of the unit such that constant movement of air can
flow through the ventilation holes. There are 8 tubes inside this unit so it does run
quite hot. Good ventilation is definitely encouraged.
WATER & MOISTURE
As with any electrical equipment, this unit should not be used near water or
moisture.
SPECIAL NOTES
Tubes may become loose during transit. Straighten and press down each tube before
plugging this unit into the mains socket. Furthermore, don't touch the tubes after the
unit has been switched on, the tubes become very hot during operation and should
only be handled after the power has been turned off and the tubes have cooled.
WARNING!
