Crossfield sound head system: The crossfield sound head system is so-called pre-magnetization of the Not - as is generally the case - via the recording / playback head, but via a separate audio head (bias head), which is opposite the aforementioned recording / playback head. This sound head arrangement enables signal modulation over the entire audio frequency spectrum without any impairment due to the premagnetization, as is the case with other sound head systems.
