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.):

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.

One of the most difficult things for a power

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

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.
