Lend Me Your Ears
Exposure to extremely high
noise levels may cause per-
manent hearing loss.
Individuals vary considerably
in susceptibility to noise-
induced hearing loss, but nearly everyone will
lose some hearing if exposed to sufficiently intense
noise for a period of
time. The U.S.
Government’s Occu-
pational Safety and
Health Administra-
tion (OSHA) has
specified the per-
missible noise level
exposures shown in
this chart.
®
According to OSHA, any exposure in excess of
these permissible limits could result in some hear-
ing loss. To ensure against potentially dangerous
exposure to high sound pressure levels, it is recom-
mended that all persons exposed to equipment
capable of producing these levels (such as the
M•2600) use hearing protectors while this unit is in
operation. Ear plugs or protectors in the ear canals
or over the ears
must be worn when
operating this am-
plification system
in order to prevent
a permanent hear-
ing loss if exposure
is in excess of the
limits set forth here.
INTRODUCTION
Our Fast Recovery (FR) amplifiers perform
better than conventional designs when presented
with adverse conditions such as clipping. Con-
ventional designs use lots of negative feedback
to provide stability and lower distortion. When
clipping occurs, this “feedback” causes high-
frequency sticking, keeping the amplifier
“latched” in the clipping state longer than
necessary. This results in painfully audible
distortion. The Fast Recovery design eliminates
this high-frequency sticking and allows the
amplifier to remain stable when powering
highly reactive loads at high volume levels.
Carefully read and follow all the safety in-
structions explained on page 2 and throughout
the manual. The Quick Start guide on page 4
gives an overview of the amplifier, and the rest
of the manual explains the wealth of features
and operating instructions in loving detail.

At Mackie, we know what it takes to be
roadworthy. After all, our mixers have traveled
all over the world under the worst of conditions,
and we’ve applied what we’ve learned to the
mechanical design of our amplifiers.
Reliability is paramount to sound reinforce-
ment. That’s why we use double-sided thru-hole-
plated fiberglass printed circuit boards. That’s
why our engineers have subjected the amplifier
to the most rigorous and fiendish tests imag-
inable to fine-tune the design and extend its
limits beyond those of ordinary amplifiers.
