Dolby C-type used in the Technics RS-B900 provides 20 dB of noise reduction above about 1,000 Hz, fully doubling the amount given by B-type. The Dolby HX PRO system provides precise bias control during recording to reduce distortion and improve linearity in the high-frequency range, the result is recorded sound that is highly faithful to the original. The three-head configuration of the Technics RS-B900 requires a Double Dolby system, one for recording and one for playback. Dbx Type II found in the RS-B900 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 RS-B900 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. All main transport commands can be issued remotely with a wireless remote control.
