Manley MONO VARIABLE MU LIMITER / COMPRESSOR 5670 MODELS - Manual (Page 3)

INTRODUCTION
!
THANK YOU!...
for choosing the Manley Laboratories Mono Variable-MU Limiter Compressor
Amplifier. The heart of this limiter is the unique 5670 variable-mu vacuum tube
which can handle a widely varying range of input signals in a rapid-acting manner
without introducing harmonic distortion. This limiting circuitry was designed by
David Manley over thirty years ago. Our current version of this 1960s design
combines that classic sound with the precise cleanliness of modern componentry.
Please take a few moments to read through this manual, there may be features and
information about this unit that are unfamiliar to you.
Thank you again, and please enjoy!
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 4 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.
