INTRODUCTION
THANK YOU
Thank you for selecting the L2M Mastering Limiter and thereby making it a part of your
art. The L2M MkIII M/S Version is the third generation of our L2M platform, now in
it’s 12th year of production (2011).
We classify the L2M as a mastering limiter because it was designed with the specialized
requirements of the mastering engineer in mind. Features such as a choice of outboard
power supplies (all tube or solid-state), true bypass, 1dB 24-step attenuator, 1dB 10-step
Limiter Feedback, Limiter Response, Mid/Side function, and multiple calibration points
all contribute to its effectiveness in the demanding application of mastering. Further-
more, the L2M is equally at home in tracking and mixing situations.
The L2M is an optical limiter based on classic designs of the early 1960s, however, the
L2M is the beneficiary of many significant improvements and represents what a truly
refined optical limiter can be.
Among the more notable performance features of the L2M are it's sonic excellence, ver-
satility and stable frequency response while limiting program material. Corrective EQ,
following the L2M, is simply not required as with many limiters. Your work stays intact,
just as you need it to. While providing unobtrusive compression/limiting action, there
is no undulating bottom or loss of openness, even in the heaviest of limiting situations.
For over a decade, the L2M has been installed in some of the finest mastering and re-
cording studios throughout the U.S., Europe and Canada and has been the primary dy-
namics processor on many major record and film releases.
Please read this manual carefully as it contains information essential to the proper op-
eration of the unit. We welcome your comments and encourage you to write or call.
Thank you again, and please enjoy!
