Hum on sound outputs

Post by Mark »

I have a fit-pc2 on my boat. When the battery charger or inverter are on, there is a loud hum on both the DVI audio and the line out audio, even when the computer is powered down. I can disconnect the power input to the computer and the hum goes away, and reconnecting it will return the hum even before the computer is turned on.

Is there some kind of filter I can put on the power connection that can eliminate this hum?

Hello Mark

Fit-PC2 does have an audio out on it's DVI out.
You should isolate the amplifier ground to get rid of the hums.
