The Harman Kardon CD391 is a stereo cassette deck with Dolby B/C and HX-Pro noise reduction, it was introduced by Harman Kardon in 1982 with a manufacturer suggested retail price of USD $575 and discontinued 3 years later in 1985.

The main features of the Harman Kardon CD391 are: 2 heads, analog 3 digit tape counter and memory stop, manual tape type selection with support for normal, chrome and metal tapes, dual 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 CD391 are generic digital peak reading meters with multi-color indication to provide visual saturation level of tape and peak hold for easy adjustment of optimum recording level. Full-logic transport controls used on the CD391 let it respond to the slightest finger contact for fast and effortless transport function selection.

Dolby C-type used in the CD391 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. To further maintain recording accuracy, the CD391 incorporates a switchable multiplex filter. When you record FM stereo broadcasts, the MPX filter of the CD391 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.
