audio-technica AT-VX50 VOCAL Mixer Product Description It has a vocal cancel function (karaoke function) and seems to be able to add echo. I don't know much about it, but it seems to be a fairly old product. I was able to confirm that it powers on, but I haven't checked anything else. Since I haven't confirmed all the functions, this is being sold as a junk item. There is some damage and scratches on the item, so please check the condition of the item in the photos. Please consider this after understanding the description. Thank you.
