Donner DKA-20 Keyboard Amplifier 20 Watt Keyboard AMP with Aux in and Two Channels, Bass Guitar Amp, Piano Amplifier, Electronic Drum Speaker Support for Microphone Input

My Kawai ES 100 digital 88-key piano has a beautiful sound that was not captured by its integrated speakers. So, on a lark, I bought this Donner kit to pair with it. I love that the Donner box included everything I needed (no reason to buy another cable): the two-piece power cable, and a 1/4 inch amplifier cable with L-shaped end that plugs into the Mono L output on the left hand back of my ES100. Pop the other end in the little amp and we are off. If you have this exact keyboard, you can turn off the internal speakers by holding down the Function key and hitting C# 7 black key (page 45 of the keyboard manual). This amplifier is CLEAN. That's really key as I can place it 5 feet from my keyboard and there is no feedback and no annoying buzz when I'm not playing. It's just quiet. The volume power is better than the keyboard's internal speakers, matching it at about 60% volume amp to 100% on keyboard internal speakers, if that helps. Frankly, if I was playing to a church group in a middle- to large-sized church, or over other instruments, I would want 35-50 watt amplifier. But for household, small gatherings, this is great. Unlike my internal ES100 speakers, I can modulate the treble, midrange, and bass, which is nice. I can add a second instrument with line 2 in. And it has a 1/4 inch headphone out jack that is better placed for me as this sits aside my keyboard, than the headphone jack in the rear of the piano itself. So, all in all, this Donner 20 watt amp offers many sound improvements and conveniences that are worth the modest price. The only time I don't practice with this amplifier turned "on" now is when everyone else in my house is sleeping (then I use the ES100 internal speakers set low or the headphones). I recommend this amplifier for a home setting.

Really clean sound. Great for playing small venues. I use it with an EWI.

First the positives: very good price. Compact and dials on the front, love this feature. Clear sound. Perfect for room practice. The negative: not enough volume for any small gig. It could've use a little more volume. But then again, if you want a more loud Amp, you need to invest more money with more watts of power. In a nut shell, it delivers what it should for the money spent. Thanks

Love this amp!!

easy set up and nice sound for a small practice amp

Impressive, this small amplifier did more than what I was expecting.

I thought for the money this is a very good amp. I'm only using it for personal home use. The sound is very good. Amount of volume is great, level 1 is very loud and clear. It also is light weight.

Greetings, Initially, this product worked well. We were really happy at first. However, before the year from purchase this speaker stopped working out of nowhere. It doesn't turn on. We never used it as maximum. The cable adapter is working but the speaker isn't. I didn't have enough faith to do the warranty process because like insurance companies, my experience is that companies try to find ways NOT to honor the warranty. When I decided to give it a try and contact DONNER they won't honor their warranty because it's already past a year since the day of purchase. However, countries that are not the USA get two years of warranty! Why the American consumer is being penalized with 1 year vs the 2 years EU consumers get in warranty is beyond me. I should have made my claim before the year. It's a shame because initially this product did a good for my son's keyboard but now we are stuck with an almost new speaker that doesn't work. Speakers that break before a year of use shouldn't be in the market. This is what I get for trusting DONNER. To the American consumer, beware of DONNER because they intentionally give more privileges to non USA consumers.

Before this one, I never thought of getting in external amp for my keyboard. I picked one (this one) because I was curious to have more controls over my sound, but also because I play guitar with a modeler and I wanted to try it as a keyboard amp is supposed to be transparent. If only for the low-mid-high controls, I now really NEED an amp to play on my keyboard. The sound is so mucu more rich. And having a bigger speaker like this one makes the low notes resonate through your body. Even if it's only 20 watt, its plenty loud, trust me. The amp looks also built very sturdy, that is good for those who want to carry it to different places a lot. One of the best part is that it has an AUX in, so I can plug my laptop/tablet and play with youtube videos. I was really surprised of the sound you can get from this thing as it is really small and lightweight. Secondly, I tried it with my modeler (Hx stomp). I can tell you that is sounds just fine for bedroom playing or for living room jamming with my friends (cajon + bass + guitar). Probably not loud enough for rehearsal with a real drum, but it is not to be expected. The sound quality was surely good enough with the modeler so that I can have fun and not focus on trying to improve the sound, which I ofter do. Finally, I plugged an FX pedal between my digital piano and the amp so I can have crazy reverbs or other effets. It is really a lot of fun let me tell you! This little amp is now my everyday living room companion for guitar and piano. Sits in a corner where I can barely know it's there, and making my playing time way more fun! Just a thought, I didn't try it but as you can also use it with a microphone, and as there is an AUX IN, you could also use it for Karaoke if that's your thing. I am considering adding a second one so I can have one on my left and one on my right, but that is just me being picky about my setup.

Excelente amplificador lo conecte a mi teclado y se tiene un sonido bastante bueno, recomendado para espacios pequeños.

I just got this amp, Donner DKA 20 and to use with my electric guitar that I'm learning to play. It is a pretty loud and crisp/clear sound to it. it really sounds amazing! It is rather a compact unit that packs a lot of punch! I have it pictured with my electric guitar for you to see the size comparison. There are 2 inputs, which can be regulated individually. There is one aux in, which I have used to play music from my phone on, there us a headphones jack on it as well, for the times when you just want to practice for yourself. It is sold as a keyboard amp, but it works really well with my guitar and it sounds just great! It's not a very heavy unit and looks to be well built. It is solid. I highly recommend it. It was well packaged, came with the power adapter and a long 1/4" audio cable with an 1/4" to 1/8" gold plated adapter. A very strong and sturdy handle is built-in right on top of this unit. A really nice unit with amazing sound. I am very happy with this purchase and I highly recommend it!

Excelente tamaño para transportar, sonido bastante pontente y definido aun en espacios abiertos, por lo que para monitorearte mientras tocas con el resto de la banda está super bien, lo compré por los 2 inputs y la salida DJ para la mezcladora, en fin muy satisfecho con el producto. Lo mejor el precio!

Cumple perfecto con lo que necesito para amplificar mi sintetizador y practicar mis piezas con su doble canal imput.
