High pass filter after the PI preamp !?
Hi all,
There is a high-pass filter after the some PIs preamp like Barracuda-PI or XL500. What advantages it has?
I tested one on the my HH and noticed that when a target is detected, the output of the preamp(after the filter!) becomes bent above the zero line... Why? It causes that secondary sample acts wrong.
