This unit is a 1/4 track, 4-channel, expandable stereo duplicator that produces four copies from a cassette master at 30 ips. or 76 cm/s (16 times normal speed). This unit has One Button Operation. It rewinds the master and copy tape, starts the duplication process, and rewinds both tapes at the end of duplication.
