The whole point of a powered mixer is lots of power, right? That's why there's a real FR Series High-Current, Fast-Recovery power amp inside every PPM Series Powered Mixer. It's designed to run all night into brutally low impedances and sound clean even when driven hard. Mackie starts with a massive toroid transformer and 2 unusually large storage capacitors with 720 joules of energy storage capacity. In fact, the PPM power supply is so robust that it can run on as little as 80 volts at the end of a long, skinny extension cord during a brown-out. Then they add their Fast Recovery circuitry that reduces latching distortion so PPM Series mixers sound good even when driven well into clipping. Also included is an SCR crowbar circuit for speaker protection. 1200 real watts/2 ohms from twin 600-watt FR Series High-Current power ampsPower amps switchable as mains or main plus monitor8 mic/line channels with master phantom powerInserts on channels 1-6Active 3-band EQ on each channel2 separate 9-band, audiophile-quality graphic EQs-- one on mains and one on monitorStereo line inputs on channels 7 and 8Level-setting control & LED on every PPM mixer channel-makes setting input levels a snapMil-spec fiberglass circuit boards (instead of cheap phenolic) resist physical impactAmp routing switch assigns power amps to mains or mains + monitorsHefty 10,000µf storage capacitors for high peak power reservesMassive toroid transformer for high current output
