Borrowing heavily from the amplification circuits D’Agostino developed for the Momentum amplifiers, the three-channel Master Power 3+ adds flexible crossover, bussing and bridging capabilities that optimize it for any system, from traditional two-channel to the immersive sound of Dolby Atmos and DTS X.

The switchable crossover filters the bass out of any channel to drive satellite speakers—or the mids and treble out of any channel to drive a subwoofer. Of course, any or every channel can run full-range, too. A single audio signal can be routed to one, two or all three channels. Channels 2 and 3 can be bridged to deliver 1,000 watts into 8 ohms. Power can be controlled through a 12-volt trigger input or through RS-232, and the Master Power 3+ is rack-mountable.

Like the Momentum amplifiers, the Master Power 3+ is built by hand in D’Agostino’s Arizona factory, using expensive through-hole construction for the best possible sound quality and reliability.
