Level meters used on the RS-B85 are generic digital peak reading meters with peak hold for easy adjustment of optimum recording level. Full-logic transport controls used on the RS-B85 let it respond to the slightest finger contact for fast and effortless transport function selection.

Dolby C-type used in the RS-B85 provides 20 dB of noise reduction above about 1,000 Hz, fully doubling the amount given by B-type. The three-head configuration of the RS-B85 requires a Double Dolby system, one for recording and one for playback. Dbx Type II found in the RS-B85 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. All main transport commands can be issued remotely with a wired remote control.
