desertcart.com: 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 : Everything Else

Review: donner keyboard amplifier - Great amp for the money. Plenty powerful and very light weight. Perfect size. It even came with a music instrument cable. Delivered so quickly. Love it!
Review: Works well with my Kawai ES 110 Keyboard - 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.

## Questions & Answers

**Q: Does it have Bluetooth capability?**
A: No, it is not Bluetooth capable.

**Q: I just bought a dka-20, but the little black protective plastic piece on the corner of the amp had broken off in shipping.  Where to get replacement?**
A: Dear Customer, we deeply apologize for the defective parts and we will work with Amazon to avoid such an issue from happening again. Could you please contact our after-sales through the order page directly? We will do our best to assist you to resolve it.

**Q: Can I use this for an electric guitar?**
A: It will work for a guitar, but keyboard amps generally give good definition of a wider range of tones that are not necessarily required for an electric guitar. That's why an entry level keyboard amp usually costs more than an entry level guitar amp.

**Q: When you use the line out to a mixer, does it mute the amp?**
A: No. Can still be used as a stage monitor.
