Thank you for viewing. This is a Roland M200i digital mixer. I used it for small live performances until about six months ago, but I'm selling it because I no longer use it. I turned it on for the first time in six months, and it powered on without any problems. I haven't been able to test the sound output because I don't have a testing environment. I used it by connecting it to a MacBook, so I don't know if it can be used with an iPad. The M200i is still very popular, and it has so many amazing features for its size that I couldn't even use them all. I think it can handle a decent-sized sound system if you use a digital snake. The power adapter is for some reason an LG one. There are no problems with its use.

Since this is a used item, please understand that no claims or returns will be accepted in any case to avoid any trouble.
