Mackie FR-1400 Professional Stereo Power Amplifier
Building on Mackie's legendary "Fast recovery" design, the next-generation FRSeries professional stereo power amplifiers deliver new levels of performance and reliability to your live sound system. Tens of thousands of satisfied owners have come to appreciate FRSeries sound quality and system-enhancing featuresand with good reason. You get ultimate power, ultra-clean sound, and affordability in one high-performing package.

Fast Recovery Revisited
Fast Recovery circuitry was born when Greg Mackie and his team of world-class amp engineers developed our original line of Mackie power amplifiers. Their innovationand late nightsresulted in a revolutionary technology, one that delivered power without sacrificing sound quality. Unlike traditional negative feedback power amplifier design, which can cause a power amp to latch in clipping mode, Fast Recovery circuitry instantly recovers from clipping. The result is no latching, and way better sound.

After our original FR amps debuted, it wasnt long before they developed a reputation for having great sound and reliability. Being the astute Mackoids we are, we thought it only made sense to incorporate FR technology into a variety of our industry-standard products, from HR studio monitors to SRM450 Active loudspeakers. To this day, the technology stands the test of time, delivering sound quality unmatched by other power amplifiers in their class.

Brawn Over Brains
Mackie FR-1400 Professional Stereo Power Amplifiers are all about brute force. These traditional Class A/B and Class H amp topologies feature a massive toroidal transformer, huge storage capacitors, state-of-the-art output devices and back-to-front cooling via a variable speed fan. Delivering enormous amounts of current into extremely low impedances, plus lots of dynamic power reserves, you can trust that clipping will be kept at bay and your sound will always be true. Especially when it comes to extreme transients, these amps are ultra-responsiveyour kick drum will devastate, your snare drum will cut, the bass guitar will pulse and punch, the accordion will.OK, so an accordion has no aggressive sound attributes that we are aware of, but you get the point
