Low Pass Filter problems

I installed LP filters on H1 and H2, they are working great and set to 16kHz, they cut my noise from 60mV to 16mV.  However, I expected the thresholds to reduce, but they haven't, so whilst I have really low noise, I actually detect less signals as the signal peaks have been smoothed a little and now don't make the thresholds.

I am running in auto mode, should I be in manual and are there any suggested settings?

Hi Robin,

after adding 2 ICs to the H-field section I started in manual mode setting different values and settings followed always with hours of observation about the results. I never found a combination which was better than automatic setting. Once I disabled noise adaption, set to manual much lower values  (I have also very low noise here) but after some time I have seen that the threshold range was set automatically complete out of the range of the signal from one of the antennas.
So finally after a lot of experimenting I moved back to default and automatic mode. Mostly I'm on page 2 or 1 or maximum 3 refering to "Efficieny" and I'm happy with this.

If you also start with experiments take your time and maybe you have more luck. I'm interested in results!

Cheers
