The amp cuts off all the time. It won't run past half way and it started to smell like it's burning up. I've only had it 2 months. It also does not work in mono. The left side blew out the other day, I'm sending it back. It's a TOY!
I ordered it hoping it would power my practice space rig. Unfortunately, it has a real irritating buzz in 1 channel (it also sounds real band if I bridged it).Basically, you'll get what you pay for with this, I'll be shipping this back soon :(
I ordered the XP-450 amp and the first one was DOA right out of the box. But it was replace right away and the second XP-450 has performed great. We use it every weekend, I might buy another.
We use the XP-450 amplifier at about half power for our monitors and it works great. Our full PA set-up includes two Behringer EP2500s, (one for the subs and one for an extra set of drivers when doing outdoor gigs). The main speakers are Yamaha 15" Club Vs driven by a Yamaha XP 5000. Although the Gem Sound XP-450 does not have a lot of features such as limiters, etc., it has more than adequate power and sound quality for our uses. It would be nice if it had a ?power-on? LED on the front, and quarter inch input jacks instead of just the RCA and XLR inputs,. We?ve had this unit about six months and have not had any problems with significant noise or reliability. If we need more monitor channels, we may buy another one.
Where do I begin? This amp sounds like 50 watts per side instead of the 200 watts listed. When bridged it doesn't work. It has no bottom end. Adding an EQ helps some, but not much. This amp would be OK for a dorm room or garage, but don't try to take it out and do a show. It will cut out all night. Spend more and get a better brand. I purchased a Yamaha after my nightmare with this Gemsound amp.
I run this amp bridged mono into a 4 ohm load rated at 700Watts like this.(4 x 12" 4ohm speakers. (2 in series then both of those in parallell to get my 4 ohm load.) This amp kicks for the money. At about 3/4 of the vol knob the amp starts to go into saturation and clip ever so slightly...but it u back off just a bit your good.Great amp may buy another but I may step up to the 550 gemsound model.
This amp has a decent sound but clips even if I play at 1/4 volume. It's on its way back to the store. Don't waste your money.
