12-channel 2 x 800W Powered Mixer with Built-in Effects. Mackie continues to create live-sound solutions with the PPM Series powered mixers. These PPM mixers are surprisingly lightweight, but tremendously powerful with the PPM1012 sporting two individual power amps, with one 800-watt power amp handling the mains and one delivering 800 watts to the monitors. Mackie designed the PPM1012 with Class D amplifiers that produce maximum power with minimum heat. A built-in limiter protects your speakers from damaging peaks. All of these design elements merge to create a rugged and powerful mixer to make the PPM1012 the centerpiece of your live rig.
