MORE INFORMATION

■ Fast Recovery design

for improved transient

response and recovery

from clipping

■ Rack-mountable (2U)

with rear support rails

for extra support

■ Separate left and right

detented gain controls,

calibrated in both dB

and volts

■ Balanced XLR and 1/4"

TRS input jacks

■ Balanced XLR thru jacks

■ Heavy-duty binding post

output jacks in parallel

with:

M•1200 —

1/4" TS output jacks

M•1400 —

Speakon

output jacks

■ 6 LED metering includ-

ing Signal Present and

Overload

■ Separate L/R Protect

LEDs indicate the

following protection

conditions:

1) Automatic turn-on

delay to prevent poten-

tially damaging thumps

and pops from reaching

your speakers

2) Short-circuit protect

with separate L/R

indicating LEDs

3) Thermal protect with

combined Ch1 and 2 Cold

and Hot indicating LEDs

■ SCR Crowbar DC offset

protect

■ Low-cut filter with

variable frequency

control (Off – 170Hz)

■ Subsonic stabilization

eliminates ultra-low-

frequency noise caused

by microphone han-

dling, stage rumble

■ Constant directivity horn

compensation with

variable high-frequency

boost control (2kHz to

6kHz)

■ Amp Mode switch for

Stereo, Mono, or Bridge

modes

■ Limiter to eliminate

clipping in both channels

■ Subwoofer mode switch

with dual-frequency select

(63Hz/125Hz)

■ T-Design Constant

Gradient Cooling Tunnel

uses two short tunnels

instead of one long

tunnel for improved

cooling efficiency and

output device reliability

■ Dual-speed cooling fan

■ Toroidal transformer for

reduced EMI emissions

The world is full of amplifiers

that do one thing – amplify

audio signals. But at Mackie

Designs, we’ve always put

out the extra effort to provide

more quality and more

features than our competitors

while maintaining a com-

parable (or lower) price.

The FR Series™ power

amplifiers are designed to

perform reliably under the

most adverse conditions,

and we’ve added a bundle

of extra features, so you

don’t have to put out the

extra bucks to buy a bunch

of add-ons or plug-ins to

make your sound system

do what you want it to do.

Meticulous Detail

Perhaps the most impor-

tant aspect of the FR Series

amplifiers is the attention

to detail in the design of

the electronic architecture.

We have incorporated a

number of unique properties

including Fast Recovery,

sustained high-current output

capability, high voltage and

current slew rate, and defeat-

able clipping eliminator, to

ensure that the output of

the amplifier is virtually

distortion-free.
