I'm selling this as I don't use it much. Power and operation are not a problem. The case shows some signs of use, but the contents (main unit) are in good condition. Manual and coaxial cable are also included. I haven't checked all the functions, so please understand that this is an NCNR sale (no claims, no returns). 【High-Performance Digital Mixer】 The DM20 is a high-performance digital mixer that combines sound quality and operability.
