This is a junk ZOOM R8 multi-track recorder with 8-track recording, 2-channel input, and an LCD display. The defects I am aware of are: * The left (←) and right (→) cursor keys do not work. * The REW key does not work. Also, since it has been used for a long time, there may be other defects, but I have not checked them. I am selling it as a junk item. I used this for instrument practice with karaoke sound sources, so I believe 2-track, 2-channel recording and playback are possible, but it is a junk item and is not guaranteed. Please note that I do not accept price negotiations.
