I wanted to point out that this amp is called MAGNUM 1200 and not 1000 which is the JUMBO 1000. I use it for 15 years and carefree, I possd before the APK and JUMBO SERIES. The Magnum 1200 is a dual power amp trs robust and reliable without saturation, it dlivre 2x600w/rms 4 ohms, 8 ohms and 2x400w/rms 1200w/rms bridg 8 ohms, it all possde protection relays + + + 2 silent fans limiter, XLR connections RCA terminals grips front and rear. A little expensive 16000ff about 1985, but it is always the 20-year APRS to spit real watts. I would do my exprience with this choice, this amp is Fidler and do not give full concert.
