MORE INFORMATION
TM
■ 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

®
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.
