* If SQRT Transfer Function is chosen, output changes severely even by a small change to
input in the region of low pressure. Because this may cause distortion to input analysis, a
technique of applying non-SQRT Transfer Function is used when pressure is lower than a
certain value. This product supports this function by setting up Low cut mode.
When Lowcut is set up as
Linear mode, apply linear
Transfer Function if
pressure is lower than Cut
rate.
