Level meters used on the RS-641 are generic digital peak reading meters. Mechanical transport controls for reliable RS-641 transport function selection. Cue and review can be used to easily and quickly locate the beginning of a passage.

The Dolby-B system reduces tape hiss on tapes recorded on the RS-641 by as much as 10 dB at the highest frequencies. 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 RS-641 filters out the pilot signal, and assuring proper Dolby processing of FM stereo programs.
