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.
