This Denon DRM-400 is a stereo cassette deck with Dolby B and C noise reduction, it was first sold by Denon in 1989 with a list price of USD $200 and discontinued 3 years later in 1992.

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 DRM-400 are generic digital peak reading meters. Full-logic transport controls used on the DRM-400 let it respond to the slightest finger contact for fast and effortless transport function selection.

Dolby C-type used in the DRM-400 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 DRM-400 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.
