What else to know about the McIntosh MC 2120?

"Back when the 2120 and 2200 were introduced Disco and live entertainment systems were a big part of our business. And keep a lid on things could save club owners a fortune. We could put two Altec 291 drivers 16 0hm drivers rated at 40 watts each on a 2120 channel and run them all day with the power guard light flashing occasionally and never have a failure. If we needed super tweeters 2 MR 902-16 HF crossed at 9 KHZ per channel were used. 2 Altec 421's in 817 powered by one channel of a 2200 never failed either. The Mac amps worked well with JBL drivers too. 2120's, 2200, 2150's and 2250's were a great series of amps. The only issues we had were keeping the back switches, the volume controls, RCA connectors and speaker protection relay contacts clean in dirty environments. Yes they don't have meters, which I love. But all the 2120's and 2200's we installed are still working as installed as best as I know. Whether it was in Cathedrals. Churches, Hotels, Clubs, or discos they worked very well. 2255's and 2155's didn't hold up as well. But 2500's the 2120s' big brother and 2600 the 2155's big brother never failed me in over the 35 years I watched them perform. Fans keeping electronics cool do make a difference if you are going to push the amps into the Power Guard range. The amp has a warm pleasant sound that I found to never be fatiguing. My only recommendation is if you like tight bass keep the speaker lines short and use large wire." -
