Special Features
- Crossfield audio head system: In the Crossfield audio head system, the so-called bias magnetization of the audio tape is not - as is generally the case - via the recording/playback head, but via a separate audio head (bias head), which is located opposite the aforementioned recording/playback head. This audio head arrangement allows signal modulation over the entire audio frequency spectrum without any interference from bias magnetization as is the case with other audio head systems.
- Reel to 8-track dubbing
- Automatic tape cut-off
- Vertical and horizontal operation possible
