This Marantz SD 8000 dbx is a stereo cassette deck with Dolby B and DBX noise reduction, it was first sold by Marantz in 1980 with a list price of USD $650.

The main features of the Marantz SD 8000 dbx are: 2 heads, digital tape counter with 4 digits and memory stop, manual tape type selection and capable of handling normal, chrome, ferro-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 directly over the head block. Additionally the heads can be easilly accessed for cleaning.

Level meters used on the SD 8000 dbx are generic digital peak reading meters with multi-color indication to provide visual saturation level of tape. Full-logic transport controls used on the SD 8000 dbx 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 SD 8000 dbx by as much as 10 dB at the highest frequencies. Dbx Type II found in the SD 8000 dbx is a simplified version of the Type I noise reduction system. The dbx Type II system was designed to be used with systems with limited bandwidth such as cassette based recorders and also uses a simple 2:1:2 compander to reduce noise. 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 8000 dbx 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. All main transport commands can be issued remotely with a wired remote control.
