FM TRANSMITTER CAUSING LOUD HUM IN SPEAKERS

[Vince4xmas]

I swapped by old WholeHouse FM transmitter out this year with a new CZH-05B. Transmitter work great however I also run an amplifier and 2 speakers. This new FM transmitter, once powered on, creates a major hum in my speakers. I tried setting the CZH-05B to low power, but saw no change. I can move the audio input cable to the transmitter around as well as the entire transmitter and get less hum but doesnt go away.

I am using a G3 director and the audio out from the G3 goes to a splitter where on audio cable goes to amplifier and the other to the FM transmitter.

Do I need to install some sort of filter?

I could move the FM transmitter to a location far away but I still need a long audio cord to the G3.

Anyone else having this issue? Please advise.
