Manley ELOP - Manual (Page 3)

INTRODUCTION
THANK YOU!...
for choosing the Manley ELOP®. This Limiter follows in the tradition of the vintage LA-2A Lev-
eling Amplifier using a passive electro-optical device to control gain. The advantage of a passive
device is that it eliminates the need to push the music through many transistors and/or ICs as
would be the case in a VCA based Limiter.
Also like the LA-2A, the Manley utilizes a tube line amplifier for make-up gain. This is one of our
favorite clean and powerful line drivers. We achieve true tube “warmth” with fidelity rather than
with distortion. Other owners of this unit love the way they can drastically (10 dB) limit without
introducing unmusical harshness. We find it extremely quick and easy to use, mostly because it
does exactly what one would expect of a good limiter when patched in. For critical vocal tracks,
this is the one to demand.
Unlike the LA-2A, we illuminate the photo-resistor with an LED rather than electro-luminescent
elements which are often slow and unreliable. We also use a solid state side-chain to drive the
LEDs. The Limiter also features a BYPASS switch that retains the tube section at unity gain.
Please take a few moments to read through this manual carefully as it contains information es-
sential to proper operation of this unit. Thank you again, and please enjoy.
GENERAL NOTES
LOCATION & VENTILATION
The Manley ELOP® must be installed in a stable location with ample ventilation. It is recom-
mended, if this unit is rack mounted, that you allow enough clearance on the top and bottom of
the unit such that a constant flow of air can move through the ventilation holes.
WATER & MOISTURE
As with any electrical equipment, this equipment should not be used near water or moisture.
SERVICING
The user should not attempt to service this unit beyond that described in the owner’s manual.
Refer all servicing to Manley Laboratories.
