R oland Edirol UA-700 Audio Midi Interface Tested. It comes with power supply use with AC100-240V (third party's product). It's in very good condition. This item is a very old device, so I would only recommend it to people with knowledge.
The OS it supports is old, so if you are thinking of using it as an audio interface, please check the details. It is inconvenient to link with a PC, but it is very convenient to use by itself as an effector, etc. Or to use it as a digital signal tester with ease. Owner's manual in English is available on the Roland website.
