Crown MA1200 Audio Amplifier 2-Channel 320-Watt (DL #5029)

This MA1200 Audio Amplifier was used extensively as part of Def Leppard's 1992-1993 Adrenalize/7 Day Weekend Tour live rigs.

Like all Crown amps, the defining characteristic of the Macro-Tech Series is sonic accuracy. A tight, rock-solid low end, with smooth, detailed highs and a well-defined midrange. This unit was checked out, and it powers up and is in working order.
