Published on 01/20/14 at 18:07 (This content has been automatically translated from French)I've owned for 10 years of pure fidelity. It is very powerful, very little heat and can even make it 2ohms despite announced 4. Reliable, not easily clip and no distortion. Very basic but a brick that will age well even years ... Highly recommended.30- macdriverzPublished on 02/14/06 at 14:09 (This content has been automatically translated from French)I used this amp in replacement of a QSC MX 1500.
The comparison stops there, the momentum is rather weak, not feel like an amp of this power.
The sound is much worse than the mx. In addition it is not the 2 Ohm, not to mention it's a crap to fix.
I compared a Usa 850 or 900 with a cheaper Cerwin Vega 98, pregnant by a hand amp, to make a true comparison: It was ace QSC disgust.13 - sebastien5359Published on 01/21/07 at 02:07 (This content has been automatically translated from French)Responding al previous opinion j uses asc amps and the United States more accurately for 5 years already have 3 d in a small way and a big one like that and they have the optimum performance even on days they are not budge and the 1300 is a true beast connected into 8 ohms on the same type of jbl ca snores of 2 bowls jbl into 8 ohms amp to half the channel's enough! c is an exellent value for money amp easily removed you immediately access even my paa Dynacor the 1200 I have sold my buddy bought the rmx IUL series sold in the wake of the no no c is a very good amp a former al pocd absolutely11

Attention racing machine on the SUB
Published on 08/11/11 at 03:48 (This content has been automatically translated from French)Here now a year since I use it on 4 sub 15 "B & C with a égalemtn Crown and Mackie. I tried all the configuration posssible with these three there. QSC Although this works relatively well in the midrange and upper midrange is at low frequencies it is best. It's hell even compared to all others ... It sends the heavy without flinching, without clip, without heat for hours and hours. It is given for 2X 65OWRMS 4 Ohms and no problem, they are there. A return of hell! There is still obviously of minor complaints:
1 the weight
2 The size 3U (not too serious but less convenient than 2U
3 the conection ... the terminal a little annoying, we would have liked to Speakon but it is only detail. …Read moreHere now a year since I use it on 4 sub 15 "B & C with a égalemtn Crown and Mackie.

Value for money, everything has been said. Ago I bought a little RMX 2450, it is okay but not the performance of the United States well above 1300.
If one day I had to be brought to have to replace it, I would do anything to find aSee less20

he gives no one gives -20 dB for 0 or 4 db is the punishment so !!!!!
silence is death and dynamic music is king! "
is a monster made more amps like that!!
DS15 on the processer is beautiful on the sub 218 in bridged is diabolical that this has sent the storm.
it's as good as better than the mx rmx. avoid using them both on a socket 16a makes it consumes as much as the guy! and as it is heavy on one side.
was EUR 300 Used twice in 4 ohm 650 wtrms as reliable and this is by far the best value for money
here I make a caesar what he was stung .....20- jujuo2Published on 03/06/10 at 14:30 (This content has been automatically translated from French)I am using this amp on the speakers RCF space 600
