    Behringer K450FX reviews

    K450FX - Ultratone Keyboard/PA Amplifer is rated 4.4 out of 5 by 9.
    Rated 5 out of 5 by from Amazing little Amp that delivers! ...I tested the amp and I was amazed at the clarity and punch of the sound. It also has plenty of power for performing small venues which I have already experienced. The XLR Mic input was crystal clear, the Eq was functional and the weight was not back breaking.Some of the effects were decent enough. I am just thrilled with amp and I would definitely purchase another one to connect both as a stereo amp which would sound awesome. Best purchase I made this year.

    Rated 4 out of 5 by from not hi fi, but good for the price we got this amp as a utility monitor fro rehearsals and some performance work. It's ok for that and having the fx unit is helpful. I wish the fx unit had more parameter control in addition to presets. The amps sound fine for the price, and as good or better than other units in the price range, but don't expect too much.

    Rated 5 out of 5 by from Great Amp for the Price Great sound, has a little bit of static depending on the keyboard you use - especially if you're using multiple channels. But overall, awesome amp for the price! The 100 FX are a good feature too.

    Rated 5 out of 5 by from works great for my needs! Use this Amp. for home keyboard practice and occasional playing elsewhere. It is not nearly as heavy as the dinosaur I got rid of. Good sound and the multiple inputs come in handy.

    Rated 4 out of 5 by from works for me. bought this for my son to start his band, he's 8. they plug my bass, my guitar and a mic into it and make noise - sounds awful but i don't blame the amp in any way. enjoy!

    Rated 5 out of 5 by from Versatile and compact. I play acoustic guitar, sing and at times use a drum machine with bass. I didn't expect that a keyboard amp would have all these advantages. The K450FX provides enough quality for small venues and it could also be a great personal monitor. I was able to get just the right sound balance. I liked the price too and I definitely recommend it.

    Rated 4 out of 5 by from Great small amp I use this amp as a personal monitor. It is lightweight, pole mountable so I can hear myself. I use it as a submixer so that a vocalist can plug in. Then I send the signal out to my PA speaker for the audience. It is great to have a small speaker for a monitor not have to listen to myself through my own PA.
