Abstract
Abstract Dual media transcribing apparatus for use with a central record/reproduce device having an endless magnetic tape upon which signals have been recorded and with a magnetic reproducing device having a magnetic tape cassette upon which signals have been recorded is disclosed. The dual media transcribing apparatus is selectively operable to control the central record/reproduce device and the magnetic reproducing device for reproducing the pre-recorded signals therefrom. Operator actuable switches are provided for selectively controlling the operation of the central record/reproduce device and the magnetic reproducing device. An audio signal processor receives the audio signals reproduced by the central record/reproduce device and the magnetic reproducing device in accordance with the actuation of the switches. A transducer coupled to the signal processor generates audible signals corresponding to the reproduced audio signals.
