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).

If you need to make more than four copies at once you can add Sound Master IV add-on modules which make four additional copies each.

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.

Features include: Individual level conrols with four L.E.D. peak level indicators, extra long life T-coreTM stereo heads, Ferrite erase heads, auto or manual operation, and switching power supply from 110V to 220V.

Also, this unit is all steel construction with a removable power cord, and comes with a protective dust cover.
