Special Features
Crossfield audio head system: With the crossfield audio head system, the so-called bias magnetization of the audio tape is not – as is generally the case – performed by the recording/playback head, but by a separate audio head (bias head) located opposite the aforementioned recording/playback head. This pickup head arrangement allows signal modulation over the entire audio frequency spectrum without any interference from bias magnetization as is the case with other pickup head systems.
Autoreverse
Magnetic brakes
Switchable equalization
Auto stop and auto power off
Vertical and horizontal operation possible
Tape type selector switch
Autoreverse with continuous operation
