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 CT-90R are generic digital peak reading meters with multi-color indication to provide visual saturation level of tape. Full-logic transport controls used on the CT-90R let it respond to the slightest finger contact for fast and effortless transport function selection.

To ensure the best response from the wide variety of tapes available adjustment of, bias, equalization and sensitivity, to optimum levels can be performed prior to recording.

Dolby C-type used in the CT-90R provides 20 dB of noise reduction above about 1,000 Hz, fully doubling the amount given by B-type. 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 CT-90R filters out the pilot signal, and assuring proper Dolby processing of FM stereo programs.

To make live recordings this deck has 2 microphone inputs to connect microphones with a jack connector. For undisturbed listening a jack connector for a pair of stereo headphones is supplied. Connection to other audio components for plaback can be achieved by a RCA cable and recording from a source by a RCA cable.
