This has been laboriously plugged into my old portable speakers from my DJ days and pipes through just fine. Shame it has no speakers of its own, but my guess is that, if you want a unit this fancy, you already have a setup. The power cord is not original to the keyboard but that seems not to cause any issues.

I’ve been told by another eBayer this is a version 1 for the keyboard, if that factors into your decision.

Any questions, just ask!
