Play Better Guitar

The M-4000 (4000W) amplifier by Mackie represents the pinnacle of Class-H power amp engineering, from a design team with a collective 38 years of amplifier experience. Mackie named the M-Series "High-Efficiency Amplifiers" for their ability to squeeze every drop of power out of standard 120/240v power outlets, delivering more watts to your loudspeakers than anything even close to their price. And not only do the M-Series deliver major watts, but they sound incredible, thanks to Class-H power stages, new built-in limiters, a sparing use of negative feedback, and perfect crossover integration with Mackie's Precision Passive loudspeakers.
