Behringer KXD15 Ultratone

Thomann GmbH finora non avevo capito la loro disponibilità ti mettono in condizione di comprare al sicuro se qualcosa o tutto non dovrebbe piacere si richiamano il tuo ordine a proprie spese ti rimborsano o potrai acquistare ancora con la solita garanzia soddisfatti o rimborsati sul vero senso della parola e non chiacchiere come che ti girano attorno e si rimacinano le loro finte garanzie, bravoooo Thomann GmbH.

Looked everywhere for reviews of a budget amp for a digital piano. This Behringer popped out multiple times. Took the gamble and I cannot be happier for the purchase. The 15"version (KXD15) has a rich bass and LOTS of power (the KXD12, due to the smaller woofer, has less powerful bass but higher response mid-range). You can use it for whatever suits your need at the moment. Instrument amp, voice amp, monitor, PA, you name it. Very versatile 4 channel stereo amp. It can be linked with another KXD15 for true stereo signal. One major downside is the constant hissing from the amp. If you need a dead silent amp this is NOT your best choice. You can mitigate a bit by lowering the eq on the mid to high freq. You'll lose a bit of volume but the amp has more than enough power to compensate. The look of the amps is incredible. Clean and modern. Avoid CH1 for a line in or an instrument. The mic amplification hisses more than the other 3 channels. Use CH1 only for a microphone unless you really need it.

UPDATE: Regrettably, last weekend the second of these PA's died on me. They lasted between 3 1/2 and 4 years respectively. Both bought in 2021. I am unable to conscientiously keep the review as positive as it was without allowing other consumers to make an informed purchase. These PA's are fantastic when working. Just don't expect them to last long. Failure mode was D14 rectifying diode in amplifier PCB catastrophic failure. Cascaded to the rest of the board. Capacitors swollen and repair unfeasible. Amplifier module replacement exceeded 50% of total unit cost. S/N for reference in case issue is familiar to anyone: S200500026AZY and S200500003AZY. Original review remains as it was what I perceived at the time. Now know the trade off for this is longevity. Both used indoors in my bedroom for piano recital and some movie/music experience.

Wish other owners/buyers the best of luck.

Very versatile amp for keboard players, with lots of inputs and I particularly like the stereo line outputs so you can monitor your stereo piano and send the stereo to the house PA if you are lucky enough to have one. Plenty of volume for on-stage monitoring but the rated power of 600W sounds optimistic to me. Great to have on-board effects, a microphone input and headphone socket too. Excellent value for money.

I'm two days in on this, but really loving it.

4 channels advertised, but Ch 1 can take XLR/mic and instrument (though they'd share volume and effects), plus you can run external sound, including your computer, through RCA cables on the back. XLR and TRS outputs can also be used simultaneously.

Pretty good on-board EQ and cool effects (100 to choose from) that you can run over channels individually or the whole. It does indeed have a good 88-key sweep and I've been happy with it handling the low end from bass guitar.

I've not compared it with Roland (at 3x the price) but for my needs this is a one-box fix-all. It's a great buy at this price.
