INTRODUCTION

Thank you for choosing a Mackie Designs
power amplifier! The M•2600 is designed to
fulfill the amplification needs of almost any type
of application, with solid design features such as:
• 2600 watts into 4 ohms, bridged
• 1700 watts into 8 ohms, bridged
• 1300 watts x 2 into 2 ohms, stereo
• 850 watts x 2 into 4 ohms, stereo
• 500 watts x 2 into 8 ohms, stereo
• Easily handles 2 ohm loads all night long
• Two low-cut filters, 2nd-order Bessel,
12dB/octave, variable from Off to 170Hz
• Two superior design active crossovers,
4th-order Linkwitz-Riley, 24dB/octave,
selectable crossover point at 60, 90 or 120Hz
• Switchable limiter
• Automatic soft turn-on and multiple
protection circuits
• Balanced/unbalanced 1/4" and XLR inputs
• XLR thru outputs, selectable to full-range,
high pass or low pass
• Speakon ® or binding post outputs
• Superior T-Design fan cooling
• Ultra low noise and distortion
• Fast Recovery design
• Five year warranty
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.

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

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.
