Qsc DCA 1222 Theatre Power Amplifier 1200 watt class AB SQ Sound Quality model For Sale

QSC DCA 1622 1600 Watt Amplifiers in VGC
As seen in the chart below, the 1222 and 1622 models were class AB for premium sound quality as they were typically used on the horns in cinemas.
These amps are workhorses that were made to live forever. They run fine at 2 ohm stereo and 4 ohm mono, so they can power a pair of 8ohm woofers with the full 1600 watts at 4ohm in bridged mode.FEATURES
