hi all.. I have found the cause of an annoying interference in my van. It is a humming, from the two speakers, which are powered from the stereo in the dash.
The humming only occurs when I use the line in option...
the line in comes from a PC half back in the hab area.. (tv, Music, internet etc)
with me still...
the hookup into the van is split between a 240V domestic unit, and a yellow step down tranny (for the 110V items)
its the yellow brick that’s causing the interference all the way down the line... i.e. if it's switched off, all is pleasant...
I don’t think it's the proximity of the tranny as such, more the fact that it's there in the lineup..
What easy/cheap things can I try...
I will try to clarify exactly how the wiring has been done.. when I get home...
