Re: Extend volume control for active speakers and Kiosk earthing.

Hi Keith

I guess my question about an earth on the PC was that it will be
connected to other devices that could introduce mains voltage due to
a fault. Ethernet, Telephone, the active speakers. I am happy that
the PC has no mains present in normal operation, just wondering if it
was a good precaution really.

Thanks for the advice on the 10k in line log pot, I will give that a
try.

Many Thanks
Ian
