· FR Series power amps don't pull power out of the ozone or switch on and off a million times a second. They're traditional inch lead sled inch designs with massive toroid transformers · huge storage capacitors · state-of-the-art output devices · and cooling systems that outperform all amps in their price ranges. They deliver enormous amounts of current into extremely low impedances - and they have dynamic power reserves to spare. The reason FR Series amps are so affordable is because of Mackie's huge investment in automated manufacturing technology · not because they cut any corners.
