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 Marantz SD-64 cassette deck are generic digital peak reading meters with peak hold for easy adjustment of optimum recording level. Full-logic transport controls used on the Marantz SD-64 let it respond to the slightest finger contact for fast and effortless transport function selection.

Dolby C-type used in the Marantz SD-64 provides 20 dB of noise reduction above about 1,000 Hz, fully doubling the amount given by B-type. Dbx Type II found in the SD-64 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-64 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.
