Thank you for viewing. The item is a MACKIE PROFX6 v3 mixer, including the main unit and power adapter. I am selling it to organize my equipment. I haven't used it frequently, so I think it's in good condition. It has a compact design and a built-in phantom power supply, making it suitable for simple online streaming and live performances. I found it very useful because it doesn't take up much space even when placed on a desk. I have checked the sound output before listing. I believe there were no particular problems, but please judge the condition from the photos. One of the rubber feet on the back of the unit is missing, and I have substituted it with another rubber foot. (Photo 10, if you are concerned, you can order one from a musical instrument store for a few hundred yen.) Please judge the other conditions from the photos.
