This is a listing for three DAM karaoke Denmoku PM600ZB units. They were in use until recently. As they are used equipment, there are scratches and marks. Simple cleaning has been done, and operation has been confirmed. The data has been updated. The batteries need to be replaced. They don't hold a charge even when charged. Please consider them as a bonus. If you don't need them, please let me know in the comments. Please understand that these are used items. Thank you for your consideration.
