[QUOTE="John Roberts, post: 91672, member: 126"] Re: Mackie m1400 amps. Any good? Reliable? Class A/B was a pretty mature amp technology even when these were brand new, but the M1200 was Mackie's first power amp. The 1400 is their second generation version of that model so the later design should have all the first pass mistakes and/or bugs worked out. They were pretty early to use plastic power devices in a professional(?) power amp, while plastic had been used successfully in consumer amps for years. Since then, metal power devices are now pretty much obsolete and plastic power devices are now a non-issue. I didn't remember that these were involved in a ribbon cable manufacturing issue or not, so perhaps worth checking or being aware of. Relatively heavy for the modest power output, so I'd be happier putting them in a budget install that humping them around for live SR. There were plenty of these sold so I don't know what a fair street price for them is now. FWIW the QSC 1450 which is the comparable model for power point uses similar technology to the M-1400 so will not have the technology advantage that I was talkign about and that the 2450 does. The street price looks a little higher for the 1450 but that is probably because they're newer and still in production (?). JR PS: Damn right I'm biased, but that doesn't mean I'm wrong.. :-) I have no motive to pimp for QSC that I also competed against, other than that the bigger QSC RMX is a better technology amp. Between the M-1400 and RMX-1450 flip a coin because they are probably more similar than different. FWIW the PV version at that power point, also class AB used my heat sink patent, so of course it would be SUPERIOR. :-) :-). While I feel bad about even mentioning this, another consideration for China haters, the Mackie M1400 was made in Woodinville, the QSC RMX was the first high volume US amp sourced from China (Peavey model I mentioned also made in China).
