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.  

WARNING!  

!  

TO PREVENT THE RISK OF ELECTRIC SHOCK 

DO NOT OPEN THE CABINET
