• Crossfield-head system: The Crossfield-head system, the so-called is not bias the Tape - as usual - on the record/playback head, but over a separate head (Bias Head), the opposite to the above-mentioned 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.
• Transfer from coil to 8-track
• Automatic tape switch-off
• Vertical and horizontal operation possible
