I'm normally recording interviews for radio, but volunteered to run house sound and record sessions for a conference. So, this was new for me. The event was taking place in an older church.
While I was recording the sessions, occasionally I would get a low-level rhythmic clicking. It soon became apparent that the noise was associated with a fan and sometimes other devices which were plugged in - and I would assume running on the same circuit as the audio gear.
I know that these will sound like questions from the uniformed - but, that's where I'm at in my understanding so I'm looking for some help so I can know better what to do should this happen again.
- How does this interference actually happen?
- Is there some device I can use to avoid the interference... in the event that I can't simply find another circuit available?
- Any other suggestions for dealing with this problem?
Thanks.
