"This a working XSFX RedSound Effects unit. Barely used, no known issues. It calculates the BPM from audio in and then allows you to add one or more effects sync-ed to the beat or beat increments. The specs below tell the story. RedSound, now out of buiness, only made a few of these. It is used but in great working order, only minor wear from use. The included power supply is not original but heavy duty (4.5amp 16 VDC). No user guide , but this unit is easy to figure out. Sold as is, no return. I only warrant that it will not arrive DOA. No Int'l bidders please, I post feedback and expect to be paid in reasonable amount of time.
