Stereo
Cassette Tape-Deck with Microcomputer Full Logic Control System
Greater
reliability and convenience in the transport system of the RT-105H are brought
about by digital control technology. A microcomputer-controlled full logic
system not only makes operation easier for you, it also makes it easier on the
deck's transport mechanism through soft-touch control and direct switching of
modes. APSS is provided for one-touch skipping or repetition of desired
selections, while the auto space control uses digital circuitry for the
insertion of blank spaces between songs. A high-performance hard permalloy head
ensures optimum performance with all types of tapes, including metal.
Performance and convenience are further assured with Dolby Noise Reduction
circuitry, full-function remote control and peak level meters.
