Mackie 808M 1200-Watt Mono 8 Channel Powered Mixer Twin 600W FR Series amps deliver 1,200 real watts @ 2 ohms and are switchable as mains or mains/monitors. The 8 mic/line channels feature phantom power, inserts on 1 through 6, and dual line inputs on channels 7 and 8. Each channel has 3-band EQ, and separate, studio-grade 9-band graphic EQs are provided for mains and monitors. The graphic EQs feature multiple summing amplifiers and precision infinite feedback band-pass filters for superior linear phase and combining properties. They are ultra-low noise, low distortion, and sound great. Rugged, injection-molded chassis. Sealed rotary controls resist dirt and dust. Features: 1200 real watts @ 2 ohms from twin 600-watt FR Series High-Current power amps Power amps switchable as mains or mains plus monitors 8 mic/line channels with phantom power Dual line inputs on channels 7 and 8 Inserts on channels 1-6 Active 3-band EQ on each channel 2 separate 9-band, audiophile-quality graphic EQs--one on mains and one on monitors Level-setting control & LED on every PPM mixer channel-makes setting input levels a snap Mil-spec fiberglass circuit boards (instead of cheap phenolic) resist physical impact Amp routing switch assigns power amps to mains or mains and monitors Hefty 10,000 f storage capacitors for high peak power reserves Massive toroidal transformer for high current output Mega-cool die-cast heat sink.
