...there are compact flourescent cans (4)
Right in the studio...?....and you have NO issues with them...???
Man...a few years ago I bought some of those spirally fluorescent bulbs that have the built in tranny at the base and are a straight replacement for typical incandescent bulbs, screwing right in.
I was using them for my outdoor lamp lights that are all around the building at various entrances and deck/patio areas.
So I'm in my studio one night...and I'm getting this weird buzz coming through my amps and monitors...it was not something I had before and it didn't sound like common AC noises...and I only noticed it at night.
I spent like...3 days hunting for the problem...finally using the main breaker box and thinking about what was different...I isolated one breaker that had one of the bulbs which was closest to my studio (about 25' away!)...and when I turned it off, the noise went away...I then looked at what was on that breaker...and there was that stupid fluorescent bulb.
I immediately removed every single one around the building and went back to using incandescent.
I was amazed that single, small fluorescent bulb with a very small transformer could cause that much noise throughout much of my studio gear!
My AC is pretty good in my area and virtually noise free…I’m not near any commercial/industrial areas…now towers…etc…but I’ve been considering a balanced line transformers for the whole studio, as they apparently eliminate ALL forms of AC noise and give your gear virtually perfect power. Combined with my voltage regulators…it could make an improvement.
The damn things are like $1200 for one 20 Amp box…and I have two 20 Amp lines (though I only run into the second 20 Amps if I like turn on EVERYTHING…which is very rare, but it’s there as a safety net and backup.
Oh...and not related to dimmers/bulbs but also an AC noise anecdote...
About two months ago I start hearing this intermittent buzz coming from my monitors...and then at one point also from my amps.
It was very low level, and for awhile I ignored it...but it really became a PITA when I was mixing. It sounded like those bug zappers...only very, very faint.
Again...spent a day chasing that ghost...finally isolated it to a coffer warmer plate I had in my studio!
Thing is...I had notice the coffer warmer wasn't really keeping my coffee warm like it use it...right about the same time the buzz started. Obviously, the electronics had become weak, and every time the warmer was turning on internally (I assume)...it would emit the noise.
Now I have a better/new warmer...the noise is gone and my coffee stays nice and hot (it's a 23W warmer!!!).
So you really have to watch what you plug in around studio gear....
