Unlike the opinion below the United States QSC 900 provides a function that allows parallel chain of several amps.

I possde this amp for 1 year, I bought from a group of varieties with returns JBL 250W RMS.Ce group had for over 5 years and I can say that a strong tape.
The amp is not only in teuf for 10 hours with no minimum cut out t winter and never really seems dconn.Il trs robust!
I found him a ngatif point, it is dpourvu output to rebalance the signal on a different amp.
I do not know the original price but for the price I pay ke (400euros) I'm ke SATIF.

I possde this amp for 6 months and I used ennormement and I can tell you it's a good bte. The conector good quality sober and Dt function of qq com: cheap shot 30/50 hz parrallle limiter and it fits perfectly for a mobile disco associated with two speakers in good used warfedale TEUs with 15 (no top) but in bridge mode on a 900w subwoofer provides the same ... I plan to buy a second to power two subwoofer. I do not think you can dir it's the best amps but it is classified in a good solid amp (use the trance psych.j 'I almost forgot a slight breath and trs shock if qq Power is not stable (eg lighting of a neon).

For me after many tests, with other machines (even more powerful bcp)
this amplifier (qsc 900) is one of the best amp in the world, automatic heat, protection everywhere, no distortion ...
If you never test a QSC 900, you do NOT KNOW what is réelement 270 w, true!! ca bangs!!
At least then, buy the radiator as if you are not a DJ, it heats, but the sound is always spot on!
Nothing to say on this product, except that of pure happiness, especially the pure taking over a 150 euro occas!
