The MA66 is a 2 Zone mixer with a 20 watt per Zone power amplifier built in. The amp section is class 'D' design so it doesn't generate any heat to the chassis. It includes phantom power, talk over that is zone assignable, and an assignable release time for the talk over circuit. With six inputs (2 mic/line XLR and 4 RCA) and an 1/8" jack on the front panel, the MA66 has plenty of input capability to satisfy almost any installation. The output section of the MA66 has 20 watts per Zone (40 watts total) that is all class 'D' design. Also includes a remote pad for both zones so you can run an external pad control to any location. The MA66 is easy for anyone to use from the front, but from the rear it is just complex enough it will fill even the most demanding installation requirements.
