Question about NRF5340 PDM GAIN signal attenuation

Hi DevZone,

My customer found that when using the NRF5340 PDM, there is significant attenuation if the incoming audio signal is a 2kHz signal.

Upon checking the specifications, I noticed that the PDM has a decimation filter with GAINL and GAINR registers.

Is it possible to adjust the GAIN values of these registers to reduce the level of signal attenuation?
