To ensure the best response from the wide variety of tapes available adjustment of, bias and sensitivity, to optimum levels can be performed prior to recording.

Dolby C-type used in the 581Z provides 20 dB of noise reduction above about 1,000 Hz, fully doubling the amount given by B-type. 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 581Z 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 wired remote control.
