Help, hum from speakers.

Post by mact66 »

I've a hum from both my speakers, the loudness is not affected by altering the volume on the amp. My amp is a Marantz PM6005.
I realise this is probably an amp problem, but does anyone have any thoughts?

Is it from every source?
My first suspicion would be an earth grounding.

Can you hear it from a far, or just from the front/face of the speakers?

Any way u look at it it could be lots of stuff

I can easily hear it without being close to the speakers. I it's also there when I switch sources.
