Behringer Ultratone KXD12 600W 4-channel Mixing Keyboard Amp
Gearank High Notes
The Ultratone KXD12 appeared on our recommended list for Keyboard Amps Under $500 from September 2017 through to November 2018.
This amp comes with a basic 4 channel mixer. It has an XLR input that works well with microphones that only require phantom power up to 15V and many musicians report using it successfully as a small PA system to sing and play through at the same time.
This includes both keyboardists and singer/acoustic guitarists and it comes with Behringer's FBQ feedback detecting system to help with that application.
The KXD12 is also used by electronic drummers and even bass players because the 12" woofer handles low frequency transients quite well while still retaining the sparkle at the high-end due to being bi-amped and having a 1" tweeter.
Its Stereo Link feature allows you to connect two of these amps together to produce a wide stereo image on stage.
One drawback is that the 7-band EQ is applied to all channels rather than giving you the option to select which channels to apply it to, but this is common with keyboard amps.
We've seen reports from a few people who have complained that the power rating is not RMS saying that it sounds about as loud as a Roland amp rated at under 200 watts.

The Behringer KXD15/KXD12 Quick Start Guide at www.behringer.com says "+15 V phantom power is available to power condenser microphones". You say the opposite for these Behringer amps. It would be nice to know this.
You are correct. Thank you

You are correct. Thank you for pointing that out - I made a mistake which I've corrected above.
Being a multi-instrumentalist

Being a multi-instrumentalist (bass, guitar, drums/perc. keys & vocals), I do appreciate combo amps that are flexible & can do many roles with a high degree of performance. Also, my basses & guitars have been mod stereo & even as inconvenient as it is; I either needed a multi-channel amp or two identical amps. My to go amps are the Roland Bass Cubes & own pairs of the Cube 40 & 60. Many, including a Pro A/V company I used to work for; "fu-fu" Behringer. Of the dozen or more Behringers I own, the LCD screen of a DEQ-2496 is the only one I have not been able to fix, yet. An MX-1804FX (amazing sounding pre's) mixer got a high alcohol content Malbec wine got spilled right on the faders & I got an identical cheap used one. The old one is a parts source. Even as Behringer uses toroidal transformers for most of their power supplies, they do have issues with power regulation. Ever since I decided to use Tripp-Lite power conditioner/regulators (LS606M & up. See https://www.tripplite.com/products/power-conditioners-tower~23-110), I have avoided equipment failures both at home/studio & at gigs (clubs are famous for horrible electrical installations, that will mess up your gear). But going back to the KDX12. As with the Roland Bass Cubes, I have used the KXD12 for everything from instruments to mains & as monitors too. My favorite speaker brands are Eminence & E/V. E/V are particular about selling you their raw speakers & so does Turbosound. So the alternative is Eminence. But those Turbo sound... wow !. On the KXD12 they just kick butt. For quite awhile I'm a 5 string bass player & the D note on the B string can be too muddy on most cabs/amps. Not on the KDX12 & the clear definition rivals my bass big rig. A Soundcraft Gig Rac 1000st, powering a Bag end 2x10" & an E/V 18" sub (both at 4 ohms). So yes. Behringer can have "ify" reliability, have hard to find "sweet spots". Almost impossible to fix, etc. But one thing I like is how good they sound. Enough said, ciao for now y'all. Oh, post data scriptum. If you can find a used Gic Rac 1000st in good shape, let me know. I want a 5th one & I might sell you one that I have reconditioned (for being a MosFet amp, it has a nice "warm" sound. See https://www.soundcraft.com/en/products/gigrac-1000st).
