FWIW the PV version at that power point, also class AB used my heat sink patent, so of course it would be SUPERIOR. Between the M-1400 and RMX-1450 flip a coin because they are probably more similar than different. 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.
PS: Damn right I'm biased, but that doesn't mean I'm wrong. The street price looks a little higher for the 1450 but that is probably because they're newer and still in production (?). There were plenty of these sold so I don't know what a fair street price for them is now.įWIW 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.
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. I didn't remember that these were involved in a ribbon cable manufacturing issue or not, so perhaps worth checking or being aware of. Since then, metal power devices are now pretty much obsolete and plastic power devices are now a non-issue. 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. 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. If you buy them, keep in mind, they are disposable.Ĭlass A/B was a pretty mature amp technology even when these were brand new, but the M1200 was Mackie's first power amp. That amp had been bullet proof since about 1998.
Took a big drop and had a circuit board crack and broke several traces. That amp finally died and was not worth fixing. Now, I also had a Mackie 1200 amp that I liked even more, even though it was less powerful. I would put them is the same quality league as the RMX amps. I wouldn't buy them if they are the newer versions from about five years ago. Later on, Mackie came out with a newer line of amps that didn't fair quite so well as the originals. So ignore the biases that some may have, strictly looking at them from a performance point view, they work. These are the monitors for the EDM DJs, gets very loud, run into limiters for hours on end in 90 - 110 degree weather. One run stereo at 8 ohms for a pair of TCS TM112 and two others run mono bridged at 8 ohms, each powering a TCS 1800 sub. I use them almost every single week for Texas headphones. Put a box fan in front of it and it came back on within a couple minutes and stayed on the rest of the night. Bridged into a very low 4 ohm load, pushed to the max on sub duty for an EDM show. It was 110 outside, probably 120 inside the steel building we were in. I have never had one thermal except one time in an indoor venue with no A.C. I use then mono bridged at 8 ohms and occasionally at 4 ohms. I use them stereo at 8 ohms and occasionally at 4 ohms. All of them had the ribbon cables replaced under warranty.you do remember the ribbon cable issues cir a 1999 approx.
Try 'em for yourself and you'll see, FRS Series amps are simply louder, lighter and better than anything else in their class.Re: Mackie m1400 amps. Combine the FRS Series amplifiers with the Mackie Precision Passive loudspeakers, and you've got optimum performance from a powerhouse system. "Built-like-a-tank" construction and sophisticated protection circuitry ensure they will withstand the rigors of the road, and perform flawlessly during gigs, no matter what you throw at them.
With their resonant switching power supplies, FRS power amps are super-efficient and ultra-lightweight, making them perfect for portable PA rigs, too - and Grannies on Tour. Delivering more Watts per dollar than other power amps in their price range - 1660W at 4 ohms bridged - the FRS 1700 will satisfy even the most demanding systems, without making a huge dent in your bank account. The FRS 1700 power amp features Mackie's legendary Fast Recovery™ circuitry for clean, undistorted sound with the ultimate in punch and clarity - even at clipping - cause Mackie knows amps often get pushed to the limit. The Mackie FRS 1700 is a power amplifier that gives you amazing power, price and portability-for the real world.
