This is the Edirol / Roland M-10MX. It is a compact mixer with 5 stereo (10 channels total) inputs. It supports various input terminals such as stereo mini, phone, and RCA. Although it is an analog mixer, it is equipped with a 24bit/96kHz compatible AD converter, and its unique feature is the ability to output digitally from optical/coaxial terminals. For more details, please see the official product page. https://www.roland.com/jp/products/m-10mx/ After purchase, it was used only a little and stored in its original box. Therefore, I believe it is in excellent condition. All accessories are included: genuine power adapter, manuals, ferrite core, original box, etc. When I checked the operation for this listing, there seemed to be no problems, but since it is an old analog mixer, there may be some channel noise (gari). Also, the digital output terminals have not been checked. I believe it is in beautiful condition as it was hardly used, but it is still a "used item" that has been in someone's hands once, so there may be minor scratches or dirt. This is a "used item," not a "new item," so please do not purchase if you are looking for a new item or are concerned about minor details. It will be shipped with simple packaging (the original box will be wrapped in cushioning material and shipped without a cardboard box). I am a non-smoker, and no one in my family smokes. I also do not own pets. Note: The serial number/barcode portion in the photos has been edited.
