By using this type of circuit, the bias output can be controlled using only one
The strength of the bias depends on the ratio of T1 to T. The
signal line.
bias voltage increases linearly as T1 increases. (See the illustration.)

Bias
When in manual ID control mode, the bias voltage depends on which notch
(which ID level on the operation panel) the user selects. The voltage applied
at each notch is shown in the above table.
