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.
