fx on other inputs... Arrived on time, great price- Behringer is up there with the best.
I got tired of having to move my Roland KC-550 back and forth from church to home so thought I would
solve this problem and buy this highly rated Behringer K900FX and use it at home.
Playing my Yamaha CP-300 through the K900FX amp, the bass sounded thin and a little tinny on the
high end. And that's after adjusting the sound through the EQ.
Here is the main reason I returned this amp. The sound randomly goes quiet for maybe a second and then
returns. This happens randomly every 5-30 seconds. I tried different channel inputs and volume levels...no
change. It also had the same issue with vocals and keyboard played together. I used 3 different cords that
work perfect..no change!
Looks like it's time to "pony-up" and get another Roland. Either a KC-400 or a KC-600.
Update:
I decided to buy the Roland KC-600. My Yamaha CP-300 keyboard now sounds like a concert grand piano!
Amazing rich bass with crisp clean highs....The KC-600 is heavy but beautiful sounding!!!
I bought this to use for practice and in small rooms. It has a great sound and is noiseless. It was quick to interface with as it has a built in 3 input mixer. It also has a set of 24 bit digital effects and a graphic equalizer. Added to that is a selectable feedback blocking circuit. All in all, great "bank for the buck".
It is also reasonable in terms of size and weight if you need to carry it or move it around yet solid enough to survive an "active life" without damage. Nicely covered in a slightly fuzzy material that keeps looking good.

電子ピアノと電子ドラムを繋いで同時に音出ししましたが、音質も自然で、問題なく使用出来ました。値段も手頃ですので、自宅で使う分には充分だと思います。小さい所ならステージでもいけそうです。良い商品だと思います。
Don't listen too hard to anyone who's says this amp is no good for keyboards, for it's price it's pretty dam good. The 5 band EQ allows for a lot of adjustment if needed, and if you're putting a good digital keyboard through it you should be able to adjust the EQ before it even gets to the amp. NO amp of this price is going to recreate perfectly the sound of a piano, even if the keyboard you're using is a good one, you get what you pay for, but I tried others at this price and they sounded terrible, especially the Laney AH50, stay far away from the Laney. I bought this amp for a friend who's a classically trained pianist of may years and she was happy with the piano sound.
This amp kicks out some serious bass even when not boosted with the EQ, the high frequencies are clear and crisp even when using my rubbish dynamic mic. When you start to crank up the volume different sound sources can start to blend into one if you have 3 channels going at the same time, but it depends on what your're using, I had lots of weird synth sound and vocal loops going through it via a Boss RC-30. And when I say crank up I mean crank up....it's loud, you probably wouldn't need it that loud for small gigs, bigger gigs you would just take a line out to the main PA and use the amp as a monitor. What's the point in pushing the amp to the limit...use a proper PA if you need to fill a medium size room.
There is a tiny bit of hiss when you have the channel and master volumes turned up almost full, but this is perfectly normal for any type of amp. It's hardly noticeable.
The xlr mic input is exactly that, a MIC input, don't try plugging an xlr from your keyboard output as it will just clip and distort.
The onboard FX are just great, the reverb especially, lots of different options, they just finish your sound off.
I tried my electro acoustic guitar through it too (with DI box of course, don't try getting good results from high impedance pickups plugged into a LINE input without some kind of DI/preamp amp first, it'll sound bad and you may break something), it sounded great, could easily be used with acoustic guitar also.
Overall an awesome amp, I made the right decision for sure!
