Sam Rossi's review"Sounds Like Just Home!"

Roland KC-550
It doesn't get any better (at least not yet). The sound generated is as clean as you could imagine a sound being; no distortion and hardly any EQ really even needed to be done (depending on what you're playing). I'm running my Roland Fantom X8 through the KC550 and you can't do any better than Roland matched with Roland.

've tried many different approaches to getting the keyboard to sound out as good as I wanted and expected it to. It started with two Hartke KM100 amps running stereo from the keyboard. Sounded great, in fact I posted a review on them. However, after having them for just a short time I began to get a feeling that the great sound would not last in the long run due to certain very small but noticeable distortions starting to form. I'd heard time and time again that Hartke wasn't the best, so I made the move and returned them.

I then tried running the keyboard through a PA system, using various speaker choices both powered and passive; needless to say it worked out (somewhat; more so for the passive, forget the actives - nothing but distortion) but the sound generated was nothing to brag about. I quickly returned the active speakers, and am now using the passives for vocal monitors.

I had never tried a KC550 before now, and my reasons were because of playing a KC350 that was probably not EQ'ed (didn't care to check), and found the sound to be horrible. To buy a full on PA system that I know would have worked, the amount of money to be dropped into that would be outrageous and too much for just needing a keyboard monitor.

I decided to play the KC550 and really mess around with it in the store; giving it a little more time than just a minute or two, made all the difference. I'm soon planning to buy a second KC550 to run stereo link, but even with just one its a beautiful sound. Granted, I've only owned mine for one day, so we'll see what the long run brings for this, but somehow I feel it'll all be just fine. Sounds like home.

I also picked the Roland KC550 as my top choice for headphone amp on my blog - <a

Roland KC-550
For specifications, see the other reviews ...
It's been 4 years since I have it, he saw the green and not ripe: it is used for outdoor concerts in addition to a small sound system peavey. Suffice to say that cash my piano (or I'm low to the left hand), my microphone and microphone bass drum ... It operates at the limits of its capabilities (when it's a little too loud sizzling sound, is corrected).

Quality and reliability are always at the rendezvous despite these intensive utilistations (5 concerts a year outdoors).

C'estsur is lacking a bit low for the outside, so this year we are going to add a subwoofer to help him.


Everything is simple and clear.

The equalizer can easily find a good quality sound. In addition there is a button "shape", the equivalent of a loudness, to improve the sound at low volume.


Pros:-sound quality (bass punchy, clear highs)
-Reliability, robustness
-Coupling capabilities between 2 amps
-Dedicated subwoofer output (eg the Roland KCW-1, but it is no longer manufactured ...)

Cons:-heavy weight (but removable wheels)
A hair-acute aggressive, but the equalizer corrects the problem)

Value for money very good.

I strongly recommend it for those who want a powerful amp and punchy.En lighter and less powerful, the KC 350 is a very good choice too.
