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 innovation and late nights resulted 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 FRSeries amplifiers are all about brute force. These traditional Class AB 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 responsive your 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. Clean, Full Range Power FRSeries amplifiers keep it super clean with the lowest distortion in their class and at .03 THD 20Hz 20kHz, we mean looooow. With frequency response that extends well above the audible hearing range, from 25Hz to 25kHz 0, 1dB, youll be sure to get the most out of your loudspeakers, too. Weve even added a user selectable subsonic filter 30Hz, so you can protect speakers without ultra low frequency response from unwanted heat creating, transducer destroying subsonic frequencies. Simply put, FRSeries amps deliver high power performance, with remarkable sound quality, across the full frequency range. Modern Amenities With all the connections to be made in the moder
