Great amp

By neilsnow

from Vermont

Comments about QSC RMX 850 Power Amp:

This thing kicks. I have had it for 2 years and have had no problem. I have tested it as a main driver, monitor driver, and sub driver and it has passed them all with flying colors. It has amazing clarity, great punch, and keeps on going under harsh conditions. I have ran it with the clip limiter flashing full and it won't shut off. Great feature is the selectors on the back, which allow you to switch filter settings and mode settings. This is a great amp. thanks QSC for producing a great amp at such an affordable price.

Comments about QSC RMX 850 Power Amp:

I bought this amp for powering our monitors in our band, I was so impressed with it I replaced one of my DJ amps with this one. Its not overly powerful, however the sound is extremely clean and punchy! I am going to buy 2 of the the RMX 2450 to power my new Peavey duel 18" subs I just bought! Can't wait to get them....Buy this amp you wont regret it!!

Comments about QSC RMX 850 Power Amp:

I replaced a crown amp with the 850, and I love the cleaner sound I'm getting. I use the amp in my studio at home and it is all the power I will ever need.

Affordable Goodness

Comments about QSC RMX 850 Power Amp:

I bought this amp a few years ago, and had a very sucessful time amping up two no-name 2x15" speakers and djing a few small parties. This was certainly enough power to get the cops at the parties a few times and make the neighbors angry. However now shifting my focus to a pair of local bands, I use this amp to crank up bands on the same set of speakers and a Behringer Mx2004A mixer. This is ideal to crank up a band at a coffee shop or small-medium sized venue. However dont intend to get your bass man's volumes too high. This amp SUCKS up the bass, and you'll clip real fast. However having all the guitars, vox, kick and snare mixed up, and the bass a little lower, you can do just fine at a venue with volumes at maybe 90db. Any higher this amp gets hot fast, and will start clipping (noticeable distortion). If you are going to be doing small-medium sized venues and you want considerable volume, go with the QSC RMX1450 at least, just to give you that extra headroom that we all need. My only complaint about the amp itself is the fan is a bit loud, and the power switch isnt the best in construction...overall very good

keeps on pushing

Comments about QSC RMX 850 Power Amp:

I run a weekly electronic music night. I use this amp to power 4 15s and 2 18s, it works hard every show. It has never over heated or shut off. It lacks in power for my use but has been relyable for every show. It does clip rather easily, but this could be solved with more power. Either way the amount of sound I can squeeze out of this amp is awesome. I have been inspired to make a purchase of a qsc amp already in shipment.

Not Bad For a Cheap Amp

Comments about QSC RMX 850 Power Amp:

I have two 850 and one 1450. They do have a hum noise when you use more than one amp in your system. I learned the hard way.

Long Lasting Powerful Amp!

Comments about QSC RMX 850 Power Amp:

This is an amazing Amp! I have had mine for years now. And it is still going strong! I normally use it for Mains and use a lighter-weight, cheaper 1200watt amp for monitors! I've never had a problem with this amp clipping, nor has it overheated or needed a fuse change! I want to get like 3 more of these soon! I'm really amazing at the fact I can forget about the amp. leave it on for 24-72 hours and nothing's wrong! I remember another amp I had burnt out when I did that once... So if you are the type to work on music or listen to it late in the night, fall asleep in your chair or go upstairs for something to drink and never go back downstairs for 2-3 days, then this is the amp for you.I wish the fan was quiter... it's hard not to know the amp is on.

Pro amp for home theater

By Mongrel714

from Florida

Comments about QSC RMX 850 Power Amp:

I bought a QSC RMX 1450 for my sub in my home theater set up after using them on the road in a few bands over the years, I never had a QSC amp fail in any way or any time so it seemed a logical choice, and when I mated that to a Sound Splinter PL-p18" driver the results were earthshaking, pun intended, An awesome amp at a great price, I hope my home insurance covers damage from low freq!!
