Bias Is an ac sig about 160khz used to erase the tape
b-4 recording,and while recording,i.e. aprox 10-40 volts
applied to erase head,simultan about 10 volts to 20 applied
to record head,level of bias to rec head shifts freq responce
of rec sig.
i.e. more bias =less hf recorded on tape.
I am a master tech,tought by a TEAC JAP ENG.
