Level meters used on the RS-B40 are generic digital peak reading meters. Full-logic transport controls used on the RS-B40 let it respond to the slightest finger contact for fast and effortless transport function selection.

Dolby C-type used in the RS-B40 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 RS-B40 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.

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.
