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

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.
