Detail 01
Keyboard amp, not a guitar amp

Independent shopping perspective
The Korena take
Keyboard amp that doubles as a small PA. For keyboard players and solo performers who need one box for keys, vocals and backing tracks.

- Solo acts running keys and a vocal mic together

Consider the trade-offs
When to look elsewhere
- Electric guitarists wanting amp breakup and character

What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Doubles as a PA system
Mic and line inputs mean you can run a vocal or a backing track through it, not just an instrument.
Detail 03
41.45 lbs
Heavy for its price class. A two-hand lift, and a hand truck helps for anything past a short carry.
Detail 04
Balanced XLR output, around 300 ohm
Sends a clean feed to a house desk or recorder over long cable runs without picking up hum.
Detail 05
Unbalanced 1/4 inch output, around 150 ohm
Short-run connection to another amp or a recorder. Keep the cable short to avoid noise.
Final check
Know before you order
- 01No keyboard stand, mic, or cables in the box
- 02Check the trunk before you buy; it is a bulky carry
- 03Vocals through it need your own mic and XLR cable
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I play electric guitar through it?
You can, but it stays clean and flat. It will not give you the overdrive or midrange voice of a guitar amp.
02Can I use it as a small PA?
Yes. It is built to handle a keyboard plus a vocal mic or backing track, which covers a solo or duo gig.
03Can I send it to a house PA?
Yes, through the balanced XLR output. That feed is designed for a mixing desk and holds up over long cable runs.
04Is it heavy?
41.45 lbs, so plan on a two-hand lift. Fine for car-to-stage, less fun for stairs.
