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 AD-F990 are digital FL peak reading meters with peak hold for easy adjustment of optimum recording level.

Cue and review can be used to easily and quickly locate the beginning of a passage.

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 AD-F990 provides 20 dB of noise reduction above about 1,000 Hz, fully doubling the amount given by B-type. The Dolby HX PRO system provides precise bias control during recording to reduce distortion and improve linearity in the high-frequency range, the result is recorded sound that is highly faithful to the original. 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 AD-F990 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.
