I purchased an item listed with the caption "Purchased new, opened, but never used, and stored at home." However, I've discovered that I can adequately substitute it with equipment I already own, so I'm listing it for sale without using it. I have confirmed that it works perfectly. Only the main unit and adapter are for sale; the instruction manual is not included. The black areas on the back appear uneven because they were just wiped clean with a wet wipe, but it is actually very clean. Below is the automatically generated description from Mercari: ↓ 10-channel analog mixer, equipped with XLR and LINE inputs. - Brand: YAMAHA - Model Name: MG10 - Number of Channels: 10 - Input/Output Terminals: XLR, LINE, Stereo Output - Included Accessories: Power adapter - Country of Manufacture: Japan Thank you for viewing.
