GX3
Superior Performance
QSC Quality & Dependability
We've been running live PA gigs since the early 1980's, starting with Peavey CS and Crown amps. Times have definitely changed,with Class D making a serious play in recent years. Lighweight is usually good, especially for OG's that have been loading/unloading gear for decades. Main thing,though,is reliability and road-worthiness...QSC has proven to be the best out of all choices,time and time again. QSC power amps?...It's standard gear in our power racks. We just purchased a second GX3 from Sweetwater and got the best price,warranty,and fastest delivery once again. Cheers!
Another great experience
Easy to find what we needed, amplifer, easy ordering, delivery, set up, working great.
can't be much better!
Excellent
I've been using a pair of these for a couple of years now for stage monitors plus Mid/High/Sub PA. They sound great and are very reliable. The light weight is a huge plus as well.
Big punch for a small amp!
Ok so my church had a qsc rmx 2450 that gave out on us we have a pair of old jbl sr 4733a so we bought this amp to get through a service and i thought that it was not gonna give the power we needed but i was wrong i have punished this amp and still does not clip nice crisp clear sound to my tops! people Qsc did there Homework!

It's not very loud
Overall, the unit sounds great. It has a straightforward design and connections, and no eq, so it doesnt color your sound. I'm using it as part of a guitar rig, with a line 6 pod and a 4x12 cab. It's barely loud enough to hear over a drummer. Sweetwater however, had excellent service as always, with fast 2 day shipping. I'll never buy from another online service again.
QSC power amp
I want to say first that the folks at Sweetwater are tremendous in their service and tech support. They definitely get an A+. This amp is working very well. Good strong and clean sound for our church. We tried a Behringer first and that did not work so purchased this one. Again pleased with this amp.
Superb Quality, Super reliable
We've these for over fourteen years now. Daily use in rental studio, plus three years in a touring rig.
Perfect performance. Zero downtime.
They've survived power-outages, Union stage-hands, drunk roadies, spilled beers, and a flash flood in Texas.
One had a noisy fan. QSC replaced it fast and free.
Other than that, no problems.
Fantastic for stereo guitar rigs!
QSC GX3
Using as a amp with guitar modelling system. Far less VOICING that other amps designed specifically for this purpose.
Solid Tank Amp
It's heavy 24,25lb somewhere. The Hz frequency response sound perfecto. Warm and balance sound with tre, mid, bass. Very balance. No regret of buying this thing to upgrade my home karaoke system. I always love product from QSC.
Plenty of Clean Power
This amp has become a classic. Plenty of clean power in a compact package.
review of QSC GX3
Very happy I bought this it has done it's job so far.
PHAT
Quiet , clear sound , built like a Mack Truck
lil amp, big punch!
This amp very sturdy. When I got it out of the box I was expecting something a lil more fragile and soft on the exterior. But its solidly built. I didn't see any difference in material construction than the qsc rmx 2450 I have also. The sound is also very clear, prestine and tight. I use this amp to power up a pair of old tweeter cqabinets and it does a very good job
Solid Amp
Power amps aren't too sexy. You just want one to sound really great and take the abuse it's gonna get regularly. This one does all that - for less than $300!. I use it for floor monitors. It sounds great. Power is clean. Lows are tight, punchy and defined. Highs are airy and sweet, not harsh at all. Excellent amp. I was going to go with a Crown amp at the same price. Sweetwater was temporarily out of stock and Tim Harrington pointed me to this one. Great call. It's a great amp! Thanks Tim.
QSC GX3
Not much else needs to be said about this amp that hasn't already been said. I would definitely say from my experience with pro audio and specifically with amplifiers, this GX3 gives you the power it says it gives. There are plenty of amplifiers out there that say they have lot's of power, but really only put a little. This amplifier backs up what it promises.
QSC GX3 was exactly what I needed
I already had three QSC GX7 amplifier for house speakers. I had an extra space in my rack and needed another couple of powered output for two sets of monitor speakers. The GX3 had the power I needed and fit perfectly in the rack. It only took a few minutes to connect up and get it working. Customer Service was awesome. This is the third time purchasing from Sweetwater, and would highly recommend using them.
Sweet amp from Sweetwater, QSC GX3
Nice, connected 3 Peaveys small wedge monitors on one channel, 3 on the other. We all noticed the clarity of sound, and had to turn the main amp sliders back a bit on sound board. And no heat, on primary monitors or amp. Nice.
Good amp for the price!
It replaced an Alesis Matica amp for the main monitors in my studio and has more power than I needed, but it had the features I wanted. The only minor problem I have is the slightly higher noise level compared to the amp it replaced. Also, if you want a operating manual, you will have to call the manufacture to get it. Other than that, it seems to be a great little amp. Time will tell.
One Great Amp
I purchased two of thes units for our Church. I originally was going to run one for the main speakers and the other for the monitor speakers. I decided initially to just try and use one amp to drive both the mains and the monitors by daisy chaining. I was skeptical that the one amp would be over driven and not be able to power both. Boy was I wrong ! The one amp provided way more power than I needed for the mid size sanctuary. The sound was powerful and crystal clear. The QSC amps seem to be very well made and come with a reputation second to none. It's all backed up with a 6 year warranty. I don't think there is any amp out there that offers as much bang for the buck !
QXC GX3 Amp
Great Product! Unbeatable warranty!
Very Solid Amp
This is a little "gem" of an amp! It is very dependable, and dynamic and the sound is very pure. It has performed much better than I expected, however I have always been a fan and user of QSC amplification. I still believe that the RMX series amps sound better, but most people really wouldn't hear the difference. The crossover mode/feature works very well and this amp really puts out a lot of output considering it's modest power ratings!! Every time I've used it I have been very pleased- wether DJing or using it for live band work. This is a very good amp- I can't wait to someday purchase the GX7!
Great job QSC!
Best amp in it's price range
Ive been working with amps from several "high end" companies. QSC really blew me away with this GX3 for $300. For the price, size, and weight, this is the best low cost amp I have ever worked with. I have 3 of them, on Sundays they are used to drive monitors at my church for the praise band, and during the rest of the week they are used for Theatre Productions to drive monitors along with the big brother GX5 and the PLX02 Series.
