Could I know, why the Trans object has to be redefined while using Pre-amp?

28:37
Is the pre-amp for all PA channels ?

30:19
Can each channels have different gain ?

Thank you for the answer, I have one more question: the pre-amplificaiton is switchable for only PA imaging? which means, for US could you bypass? If there is the time cost, how much would it be?

35:01
The PA signals are weak, how do you or your customs calibrate the signals ? For example, how to confirm the signal is 1mv or 1.1mv ? Using a signal generator ?
