problem in PAS system

[Guest 1234suresh]

Hi friends,
I am suresh a new member of this group, i am having on query i.e,
One of our public address sysem( through TCP/IP) amplifies radio noise (both FM and Am). cables were properly shielded for EMF radiation even though we are getting noise.we are using IC LM386 with 330micro farad capacitor for amplification, can any one suggest how to minimize this noise

I suggest to carfully read the LM386 datasheet
