Stereo 4-track Reel to Reel Tape Recorder (1973-77)
On conventional recorders, the signal and bias are applied to the same recording head.
Therefore, the frequencies recorded, especially high frequency signals, tend to be attenuated or erased by the effect of the bias field.
With the exclusive Akai Cross-Field Head, however, the signal and bias heads are mounted separately in opposition with each other with their centrers slightly off.
As the recorded signal is entirely unaffected by the prevailing effect of the bias field, tape can be recorded over the entire frequency spectrum with maximum fidelity even at low tape speed.

Love this machine. I've always dreamed to have a reel to reel machine and this works very well.
