Thank you for viewing. I purchased this new from an overseas shop in January of this year. I used it in a smoke-free, pet-free room. Since I used it very little, it's in near-new condition with no scratches. It is fully functional. All accessories are included. The power adapter is universal, so it can be used with domestic outlets without any problems. This is an analog mixer from OTO MACHINES, a well-known manufacturer of high-quality desktop effects units. Although there aren't many reviews and the appearance is unconventional, the build quality and sound quality demonstrate a commitment to excellence, making it a very capable piece of equipment. It's a stereo 6-channel mixer. As a competitor, a certain manufacturer also offers a very compact mixer, but this mixer is perfect for those who want more control with knobs or are looking for the distortion that only analog gain can provide. I am also listing this on other auction sites, so please understand if it sells there first.
