hi KJ Bob & Coleman,
Sorry for the delay. It was long time i had opened engineer forum. My system is differential and today i made one filter circuit with series 47uH and shunt 0.01uF. Two circuits ( each one for Mic-HI line and Mic_Lo line) and i had made and connected the filter circuit before the microphone signal reaches the SSM 2166.
i will let u know the results of RFI susceptibility with this circuit.
Thanks & Regards,
Naveen
