PB Equalizer
By switching logical input level of pin17 (for Ain) or pin18 (for Bin), you can equalize corresponding to
tape position at play back mode.
Frequency characteristics of high position (TYPE II) depends on capacitor C1 on the block diagram figure.
Figure 1 is shown by a motive of the NAB standard.
