This Gem Sound XP550 is rock solid. If you like the feel of real metal you get plenty of it here. Inside the unit the layout is spacious. The components are not squished together. This facilitates air flow from the two substantial fans along the sides. There is no shortage of internal fusing. This should avoid any serious damage to the units integrity in the event of mishap. Putting a spare fuse under the power cable insert was a nice touch from the factory. The instructions are a little vague for us novices. It took some searching on the net to make me comfortable with the hookup I have.My sound input is from the the Sub Mono Out jack of a Yamaha EMX 5000-12 mixer.(one very fine piece of equipment) The Mono Out is hooked to the left XLR input of the XP 550. The Peavy PV118 subwoofer is hooked via a 14 gauge wire with phono plugs to to the left output of the Gem Sound amp. The XP 550 is set to bridge position and the Yamaha LPF (low pass filter) switch is on. Keep in mind that this set up sends only the lowest frequencies to the PV 118 so if you really want to hear it thump you'll have to "pump up the volume". So far, I'm happy with the amp and let me tell you, my Grand Daughter and her friends can really make the windows shake.

I brought one of these amps on June 4 and it was in my hands by the 7th. The shipping of Musicians Friend is too good to be true.I had read all of the reviews so I was prepared for the odor from it being new. What I wasn't prepared for was it shutting down after 30 minutes of use. No clip lights or nothing until it shut down while I was playing at a mid level.I restarted it, and it played again for a few hours, but I kept it low and used another amp on the mains.I used it again at another show and this time the right channel went completely. So I called MF and they immediately gave me the ok to return it for a refund.It seemd to be a great value, but I'll stick to the known brands for now on.Luckily it was used just for extra speakers, but it wasn't as loud or as clear as a soundcraftmen's amp that's 15 years old and only rated at 300 per @ 4. This one is no way as powerful as its claimed to be.

Do not buy this product!

I bought this amp five months ago and it is junk! It went back to their shop to fix a bad channel...twice. Then it just stopped working all together. I wasted my money on this amp. Do not make the same mistake.

Great Deal

By dlm

I purchased two of these from the scratch-n-dent section for my church, trying to be wise with the small amount we could spend. I was nervous because I had never heard of them but I thought we wouldn't be out much if they flopped. These things worked far beyond my expectations. The bridge mode had power to spare and they were very quiet to boot. I am going to pick up a couple for myself!

Saved the day

I bought two of these, got one, second one not here yet, but... I had two shows in one weekend and was planning on my used CS-800 doing the job. The Gemsound was along for the backup, and backup it did! I set up, powered up and no sound. The Peavey finally went. So we plug in the 1 new Gemsound and back in business. Driving 2 Black widows and 2 12" others it kicked butt for 8 hours. Outdoor show, well known country band plus 6 other small groups and all were happy.Great value for any budget sound company. Can't wait to hear two of these together :)

We bought this amp (Gem Sound XP-550 Power Amp) to run our monitors and wasnt sure what to expect because of the low price but it has performed GREAT. It has plenty of power and we have not had any distortion or problems with it. The handles on the front are nice for putting it in a rack or carrying. If you need power for a low price you cant go wrong with this amp!!!

so far, so good

By the BiPolar Express

I've been using this amp for about a month now in a local club, three nights a week, 4-5 hours per night, and it's doing fine. I put electric and acoustic guitars, bass and vocals through it, and play cds on break. The binding post outs and XLR ins are awesome to have, and the sound is clean. Many complements on the sound (it's not the gear). I shop for new cheap gear at basement prices, and this amp delivers. Paid for itself first night.

Nice for the Price

We use two of these for our small church and they work just fine. We run mains and monitors through them at 250wts at 8ohms and only need to be up about 3/4 of the way...push our music just fine and we don't do just the traditional music either!!!

very pleased

By EBbnXuz.W

from Hagerstown, IN

This is my first amp so I don?t know much about them. But what I do know is that this son of a gun rocks. It is heavy a little bit. The only thing I really find that I don't like about it is that it?s very noisy. But if you got it cranked up anyways you cant hear it . As a beginner I would recommend this 550 power amp .I am happy.

great deal

By Bob Koretsky

from Portland, OR

I'm a non-professional musician that bought two of these amps to power my PA setup in my basement, and so far they work great! I've had one for a year, and just bought and installed a second one. I've had no problems with them, but I'm using them in a somewhat limited setup and have never had them cranked all the way up for 8 hours, so I'm not testing them in a professionally demanding way. If you need a pro PA amp, I recommend any of the Carvin amps or powered mixers.As far as the feaures of this amp go, they are excellent.
