To sum it up, this amp is relatively quiet (never a hum), powerful, transparent in sound and completely reliable. If you need to scrimp on equipment, it's best to at least have the basics like a good power amp to provide a solid foundation for your system and wait on some other bells and whistles until your funds allow.
I bought this amp about 10 years ago and use it currently when I perform solo as a guitarist/vocalist. I have used it with bands to power the mains and also as a DJ to power the high end and sometimes the full range for my dj system. I use it with a Mackie mixer and some JBL Eon speakers.
I knocked off 1 point only because the cooling fan does make some sound though it is not really enough to be any problem. Performing live it is still quiet enough so that the fan noise goes unnoticed. Also it is a large amp so you should check on the depth of your case/rack. It needs to go on the bottom of the rack and be supported on the bottom. Plugging in the cables can be a problem due to the amps depth. I made custom cords for the inputs so I could deal with this problem. The amp has worked flawlessly for me for years, proving more reliable than even my 2 Yamaha amps (though I still think highly of Yamaha).I have to give this amp a solid 9 out of 10. If mine crapped out tomorrow I would buy another QSC.
Never a problem- just solid reliable performance. Seems very powerful too for it's rating in my opinion.
I've bought and used much more equipment in my time than most part time professionals and have always found that buying good reliable equipment is worth the extra cost over more bargain level stuff. This QSC amp has always been a rock solid part of several of my systems and uses.

Great amp for a great price, the only downfall is its pretty heavy for its size, I have another QSC amp thats more powerful than this one and it weight half as much, don't get that one. But its worked flawlessly, has great sound, plenty of power and low noise. Other than its a bit heavy, I love it.

    Comments about QSC RMX 1450 Power Amp:

    This guy has done me a lot of service in the month I've had it. Lots of headroom and great sound. I highly recommend this unit. I use it for my PA system- I used to have a Crate 150 watt power head which I wouldn't wish on my worst enemy, and a buddy of mine and I got a hold of some speakers for really cheap, so we got this unit and are extremely satisfied.

    very good bass head..that's right

    By Anonymous

    from Undisclosed

    Comments about QSC RMX 1450 Power Amp:

    This thing thumps .. Playing live, sm-med bars etc., I run a sans amp .. tech 21 bass driver into this amp. Then out to an Avatar 2-10 and an Aguilar 1-12 .. (I also run the tech's parallel out through a distortion/effects pedal into 1-12 Hartke) And the fact that it's fallen out of the back of a volkswagen into the snow and still (after five years of similar delicate treatment) works every time ... (it got too hot to touch at an outdoor thing once, but still made a joyful noise) inspires me to encourage you to buy one of these ... It is heavy though ... but sounds great. And that's why we play ..

    Almost Perfect...

    By DJ Wyld Wes

    from Staunton, VA

    Comments about QSC RMX 1450 Power Amp:

    I'm a mobile DJ/Karaoke guy who puts this thing through the ringer. Its very reliable in the sense that it always gets through the show. I've had to tweak the pot a few times though. I don't know why but I've had problems with having to turn the dial a few times before a show to get the right channel to work. This is my second amp (first one was an 850) and the first had the same problem. Its also heavy and runs hot and is very long for my road case (barely fits) But, all in all I still give it a 4 for the sound it produces and the reliability. Thats the most important thing.

    Virtually perfect

    By MIKEW

    from North Carolina

    Comments about QSC RMX 1450 Power Amp:

    I bought my RMX 1450 maybe 4 or 5 years ago, slightly used. I use it for everything. Powers Peavey DJS4's and/or PR15's, (and monitors sometimes) for my band and also my DJ/Karaoke business. I run it stereo with the gains wide open always. The amp really thumps and has been 100% reliable.

    You can't beat this amp!

    By DJ dYgYtAl

    from Georgia

    Comments about QSC RMX 1450 Power Amp:

    I originally used Crown CE series amps without problem, but was advised to check out the RMX series from QSC. After a side by side comparison, the RMX2450 is now my amp of choice.I have used a single RMX2450 to power a pair of B-52 LX18 subs AND a pair of JBL JRX-125s without a problem. Never clipped once. My Crown CE2000 had trouble powering the B-52s alone!I've since purchased a pair of BBE MaxX3 crossovers and 2 more RMX2450s so I can split my signal into low, mid and high frequencies. Now I use my Crown to power my monitors.Yes, this amp is HEAVY but it'll never let you down, and that's what's most important to me.

    Unbeatable amps

    By JSample

    from Klamath Falls, OR

    Comments about QSC RMX 1450 Power Amp:

    I've had this amp running 12 and 15 inch subs in my home theater system every day for the last year, right at the clip limiters during loud music. It got a little warm at 2ohms, stayed ice cool at 8ohms. I haven't had any issues with distortion or thermal overloading as long as I've had it. Don't settle for lesser amps to save a buck, QSC is the way to go.

    Clean power.

    Comments about QSC RMX 1450 Power Amp:

    I was using Carvin DCM1000 amps and had issues with clipping/heat. This amp fired up a pair of JBL JXR118's just fine. Nice rumble and punch.The only disadvantage.. My amp rack now needs casters and a handle, they are HEAVY.

    worth the thump

    from fresno ca

    Comments about QSC RMX 1450 Power Amp:

    I've owned four of the RMX1450 and not once have they ever clip or overheat on me. I used it with 2 B-52s subs, 2 JBL dual cabinets and 2 15" Nady monitor speakers. I'll tell you what...this amp can tear down the whole school down. I mean it was LOUD!!! I love it and will be purshasing more of it.
