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.

    GREAT purchase for bass players!

    By ETID

    from Rochester, NY

    Comments about QSC RMX 1450 Power Amp:

    I got this amp as a cheap power solution for my bass stack... and it will give you head room like you won't believe. The best part about it, is its tiny price tag. I can't get over the price for 450W per side. Pair this up with a Sansamp RBI... and you have a high powered bass rig. Compare that to the cost of your average bass head... Heavy duty... stays cool... great piece of equipment.

    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.

    Brain throbing bass even in stereo mode

    By Nick @ Night

    from plainfield, CT

    Comments about QSC RMX 1450 Power Amp:

    This is a great amp. It is rated for 700 watts per side @ 2 ohms. but i tested it and got 925 watts per side @ 2 ohms (at about 1% thd) it's clip limiters and filters help get this power without hearing barely any distortion.

    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 ..

    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.

    I use two 1450's on my 18" subs in 4-ohm bridge, they run very cool and sound great, 1450 watts for what it is here is a great price. The filters are very useful, I use this system every week and run it hard! I have had no problems so far.

    In 3 years I went through several Mackie 1400i and then I got mad and Got the dealer to give me this amp instead. Man Am I Glad. Combined with an SVP Pro Bass Preamp A 410 and 212 cabinets, I know have all the power and Bass rig I will ever need. It is one great amp. I would recommend it for any pro bassist.

    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.

    Comments about QSC RMX 1450 Power Amp:

    I got this to replace a cheap Hafler amp and it has brought to life what an amp should do. I run it at 8 ohms on two Yamaha speakers and they give a lot a volume for a great sound! And it came with a 6 year warranty so if it does break, it will be replaced. I am very happy with this amp!

    Great Power Amp

    from Hutchinson, MN

    Comments about QSC RMX 1450 Power Amp:

    This amp has plenty of power to push my pair of JBL TR225's. 450w to each channel is a perfect match for these. I used an inferior amp prior to purchasing the QSC, and the JBL's were flat and punchless no matter how much EQing you did. Now they came alive! I plan to purchase another QSC 1450: channel 1 to power my stage monitors, and channel 2 for my standalone 15" Eminence sub. I highly recommend this amp.

    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.

    I selected this Amp to replace a 8 year old QSC USA900 poweramp, and I haven't been disappointed, drive my Stage monitors better than the USA did, and the high and low Frequency response from my monitors improved significantly.

    Comments about QSC RMX 1450 Power Amp:

    I have been using this amp for over 5 years (once or twice a week) and is still working like new. Doesn't clip on me. I use it now to power two Jbl JRX 115's and works perfect.I also used it bridged to power a sub and my friend dj used his Crown CE1000 to power the other sub at a gig. The crown kept on clipping and the qsc went all 5 hours with no problems.
