Lend Me Your Ears
Exposure to extremely high
noise levels may cause permanent 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
Occupational
Safety and
Health Administration (OSHA) has specified the permissible
noise level exposures shown in this chart.
Duration Per Day Sound Level dBA, Typical
In Hours Slow Response Example
8 90 Duo in small club
692
4 95 Subway Train
397
2 100 Very loud classical music
1.5 102
1 105 Lori screaming at Ron about deadlines
0.5 110
0.25 or less 115 Loudest parts at a rock concert
INTRODUCTION
According to OSHA, any exposure in excess of
these permissible limits could result in some hearing loss. To ensure against potentially dangerous
exposure to high sound pressure levels, it is recommended that all persons exposed to equipment
capable of producing high sound pressure levels
(such as this amplification system) 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 amplification system in order to prevent
a permanent hearing loss if exposure is in excess of
the limits set forth here.
Thank you for choosing a Mackie Designs power
amplifier! We appreciate your vote of confidence
for the folks in Woodinville who specialize in awesome and affordable audio. The Mackie Designs
M•1400 and M•1400i Power Amplifiers are designed
to fulfill the amplification needs of almost any type
of application. They boast a wealth of features you’d
expect to pay extra for — like subwoofer filtering,
constant directivity equalization, speaker-protecting
limiter, and gobs of ultra-clean power, to name a few.
Perhaps the most important feature of the FR
Series™ Power Amplifiers is the attention to detail
in every aspect of the design. 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.
Roadworthiness is only part of the picture. We
know that reliability is paramount to sound reinforcement. 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 punishing tests
imaginable, to fine-tune the design and extend its
limits beyond those of ordinary amplifiers.
Fast Recovery — where the “FR” comes from
— is more than a buzzword. It is based on real,
proven design principles. The result is an amplifier
that performs better than conventional designs
when presented with adverse conditions. One of
the most difficult things for a power amplifier to
handle is clipping. Conventional designs use lots
of negative feedback to provide stability and lower
Part No. 0000999 Rev. A 12/2001
©2001 Mackie Designs, All Rights Reserved.
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. Our Fast Recovery design eliminates this
high-frequency sticking and allows the amplifier
to remain stable when powering highly reactive
loads at high volume levels.
You may wonder why a power amp even needs
an owner’s manual. After all, you just plug in a few
cables and power it up. Well, it’s almost that
simple. There’s just a few things that we’d like you to
be aware of, and we’ll discuss those right away —
please see the Quick Start on the next page.
Then go ahead and read the entire manual. The
M•1400/M•1400i amplifiers have a wealth of useful features, and each of them is explained in detail.
Note: The only difference between the M•1400 and
M•1400i are the speaker output connectors: in addition to the binding posts, the M•1400 has Speakon
connectors while the M•1400i has 1/4" TS jacks.
Please write your serial number here for
future reference (i.e., insurance claims, tech
support, return authorization, etc.):

QUICK START

INSTALLATION
The M•1400/M•1400i amp
can be mounted in any
standard rack system (see
page 23), or placed horizontally on a floor or table. The
heavier internal components are located towards the front of the
chassis to make it easier to hold the amp by its
front handles.
IMPORTANT: The amplifier draws its ventilation
air in from the front and
out through the side panels. It needs plenty of fresh
air to stay cool.
DO NOT BLOCK THE VENTILATION PORTS
(see page 23).

Things You Must Remember:
• Read and follow the
safety instructions on
page 2, and the hearing
protection details on
page 3, before using the
amplifier.
• Never plug amplifier outputs into anything except speakers (unless you have
an outboard box specifically designed to
handle speaker-level signals).
• Before making connections to an amp or
reconfiguring an amp’s routing, turn the
GAIN
amp’s level (
) controls down, turn
the power off, make the changes, turn
the power back on, and then turn the
level controls back up.
• If you shut down your equipment, turn
off the amplifiers first. When powering
up, turn on the amplifiers last.
• Save the shipping boxes! You may need
them someday, and you probably don’t
want to have to pay for them again.
