On 7/27/2009 5:09 PM Aaron Fude spake thus:

So I've learned that electrical wires can cause 60hz interference if
running along side speaker wire or intercom Cat 5.


Dunno about "intercom Cat 5", but for speaker wires, no, no nearby power
wires can cause 60 Hz hum. If some audiophool told you this, you have my
permission to smack him upside his head.

Regarding an intercom (I assume you're talking about something actually
used as an intercom here, not Cat 5 wiring used for something else),
either 1) nearby power lines won't cause much of a problem with hum, or
2) even if they do, it's an intercom, for chrissakes; hum comes with the
territory.
