The only thing I've done with this mixer is to unpack it and put it into its flight case after a quick test. I do have the original box as well if needed. I registered it within 30 days after purchase, so it has 3 years warranty from Behringer. This has happened in about November. I decided to go with an audio interface for broadcasts, so it's waiting for it's new owner to give her a new home and fun. Feedback frequency detection EQ to filter the room and feedback Karaoke function USB audio interface High quality effect processor 6x compressor ...and lot of fun! Mixer, power lead, flight case from Thomann. Everything is brand new.
