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 suffi-
ciently
intense
noise for a
period of
time. The
U.S.
Government's
Occupa-
tional
Safety and
Health Ad-
ministration (OSHA) has specified the permissible
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 high sound pressure levels
(such as this amplification system) use hearing
protectors
while this
unit is in
operation.
Ear plugs
or protec-
tors in the
ear canals
or over the
ears must
be worn
when oper-
ating this amplification system in order to prevent
a permanent hearing loss if exposure is in excess of
the limits set forth here.
INTRODUCTION
amplifier to handle is clipping. Conventional
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 re-
sults 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 dis-
cuss those right away -- please see the Quick
Start
on the next page.
Then go ahead and read the entire manual.
The M·1400i amplifier has a wealth of useful
features, and each of them is explained in de-
tail.
Please write your serial number here for
future reference (i.e., insurance claims,
tech support, return authorization, etc.):

Date of purchase:
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·1400i power amplifier
is designed to fulfill the amplification needs of
almost any type of application. It boasts a wealth
of features you'd expect to pay extra for -- like
subwoofer filtering, constant directivity equal-
ization, speaker-protecting limiter, and gobs of
ultra-clean power, to name a few.
Perhaps the most important feature of the
FR SeriesTM 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 ampli-
fier 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.

6. Determine which
AMP MODE
is best
for your application:
·
STEREO mode (separate left and right
inputs, separate left and right outputs) is
the typical setup for amplifying stereo
signals.
·
MONO mode (sometimes called Dual-
Mono mode ­ one mono input, two mono
outputs) is for sending a mono signal to
two different speaker sets, with separately-
adjustable level controls.
·
BRIDGE mode (sometimes called Bridged-
Mono ­ one mono input, one mono output)
uses both sides of the amp to double the
power to one speaker set. An M·1400i
power amplifier, set to
BRIDGE mode,
delivers 1400 watts (into 4 ohms). Garsh!
Note: 4 ohms is the minimum impedance
you should connect to the amplifier in
BRIDGE
mode. If you connect a lower impedance load
in
BRIDGE mode, the SHORT
LEDs may
light, putting the amplifier into
PROTECT
mode.
Set the
AMP MODE
switch accordingly.
7. In
STEREO mode, connect line-level cables
from your signal source to the M·1400i's
INPUT
jacks, either XLR or TRS:
· The XLR and TRS inputs for each
channel are wired in parallel.
· The balanced XLR inputs are wired
pin 2 = hot (+), pin 3 = cold (­) and
pin 1 = shield (ground).
QUICK START
I got ants in my pants and I got to dance!
INSTALLATION
You can mount the
M·1400i amp in any stan-
dard rack system (see
),
or place it 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 M·1400i
amp 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
).
CONNECTIONS AND SETTINGS
1. Be sure the
POWER
switch is off before
making connections.
2. Turn the
GAIN
controls fully down
(counterclockwise) for now.
3. Set both
LOW CUT FILTER
controls to
their
TYPICAL marks (35Hz).
4. Set both
CONSTANT DIRECTIVITY
switches
OFF (unless you're using constant
directivity horns with compression drivers).
5. Set the
LIMITER
switch on.
Note: If you're using the M·1400i to power a
subwoofer, you probably do not need an external
crossover. Please see
for details.

· The 1/4" TRS inputs are wired
tip = hot (+), ring = cold (­) and
sleeve = shield (ground), and can accept
either balanced (TRS) or unbalanced (TS)
cables.
8. In
MONO and BRIDGE modes, connect an
input cable to
CHANNEL 1's INPUT only,
and nothing into
CHANNEL 2's INPUT.
(You could plug into
CHANNEL 2's input,
it just won't do anything.)
9. In
STEREO and MONO modes, connect
speaker cables to the
SPEAKER OUTPUTS
, either binding post or 1/4" TS:
· The binding post connectors are wired
red = hot (+) and black = cold (­).
· The 1/4" TS connectors are wired
tip = hot (+) and sleeve = cold (­).
10. In
BRIDGE mode, connect the binding post
cable like this: the hot (+) side goes in the
CHANNEL 1 SPEAKER OUTPUTS
red
post and the cold (­) side goes in
CHAN-
NEL 2's red post. Plug nothing into the
black posts or the 1/4" TS jacks.
11. Connect the other ends of the speaker
cables to your loudspeakers.
12. Plug the amp's power cord
into a
3-prong AC outlet capable of delivering at
least 15 amps.
13. Make sure your signal source (the cables
feeding the M·1400i's inputs) is powered
up and delivering signal to the amp.
14. Turn the M·1400i's
POWER
switch on
and verify that the signal present (
SIG)
LEDs are blinking.
15. Slowly turn both
GAIN
controls up:
You should hear the music and see the
SIG
and meter
LEDs flashing. If the
topmost LEDs (named
OL, for OverLoad)
are flashing, turn down either the
GAIN
controls on the amp or the source signal's
output level controls (i.e., master faders).
The point is: The
OL LEDs should never
light up.
16. For quieter listening, it is preferable to
adjust the amp's
GAIN
controls rather
than the source signal's output level
(unless you have the source's control all
the way up!).
17. Start dancing, but don't let the ants out of
your pants.
Things You Must Remember:
· 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
amp's level (
GAIN) 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.
