The Harman Kardon CD91 is a stereo cassette deck with Dolby B noise reduction, it was introduced by Harman Kardon in 1982 with a manufacturer suggested retail price of USD $265 and discontinued 3 years later in 1985.

The main features of the Harman Kardon CD91 are: 2 heads, analog 3 digit tape counter, manual tape type selection with support for normal, chrome and metal tapes, belt driven single-capstan transport.

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 CD91 are generic digital peak reading meters. Full-logic transport controls used on the CD91 let it respond to the slightest finger contact for fast and effortless transport function selection.

The Dolby-B system reduces tape hiss on tapes recorded on the CD91 by as much as 10 dB at the highest frequencies. To further maintain recording accuracy, the CD91 incorporates a switchable multiplex filter. When you record FM stereo broadcasts, the MPX filter of the CD91 can be swiched on to prevent the standard 19kHz FM pilot signal from interfering with the noise reduction system.

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.
