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 RS-M255X 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 RS-M255X 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 RS-M255X by as much as 10 dB at the highest frequencies. Dbx Type II found in the RS-M255X 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.

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.
