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 qual-

ity and more features than our competitors while

maintaining a comparable (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.

protection with

separate L/R indicat-

ing LEDs

3) Thermal protection

with combined CH1

and CH2 Cold and Hot

indicating LEDs

4) SCR Crowbar DC
