This Marantz SD-52R is a auto-reverse stereo cassette deck with Dolby B/C and HX-Pro noise reduction, it was first sold by Marantz in 1991 with a recommended retail price of USD $350 and discontinued a year later.

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 SD-52R are generic digital peak reading meters. Full-logic transport controls used on the SD-52R let it respond to the slightest finger contact for fast and effortless transport function selection.

Dolby C-type used in the SD-52R 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 SD-52R filters out the pilot signal, and assuring proper Dolby processing of FM stereo programs.

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. All main transport commands can be issued remotely with a wireless remote control.
