Typical front loading cassette deck with the cassette compartiment located on the left side of the deck. Tape eject is operated mechanically and the cassette needs to be placed with the side to be played facing forward in the cassette well.

Level meters used on the D-75s are generic digital peak reading meters.

The Dolby-B system reduces tape hiss on tapes recorded on the D-75s by as much as 10 dB at the highest frequencies. The 19kHz multiplex pilot slgnal present in FM stereo broadcasts can cause false triggering of the noise reduction system. The switchable MPX filter of the D-75s filters out the pilot signal, and assuring proper Dolby processing of FM stereo programs.

Connection to other audio components for plaback can be achieved by a RCA cable and recording from a source by a RCA cable.
