From: Michael Dobony on 8 Dec 2009 23:50 What is the best way to filter fluorescent induced hum out of a sound system? I tried setting the FD manually to filter the offending frequency, but that is not working. Mike D.

Without knowing the topology and layout the sound system in relation to the lights along with the gear used, it's impossible to offer any reasonable advice. It sounds like you need to hire a consultant that knows their stuff. Your question is not unlike going to the Dr. and saying, "doctor, it hurts when I do this." The only answer the Dr. can give without further analysis is, "don't do that". So with that in mind, turn off the florescent lights or turn off the sound system. K. K.

If they are runniing on a magnetic ballast (as $10 shop lights from Home Depot do) it's just 60 cycle hum. Any other ballast would be electronic and operate at about 35KHz approximately, so it would probably only be audible to bats. Have you tried notching out 60 cycles? Neon ballasts can make a helluva loud buzz.

However, they often induce significant buzzing noise in poorly designed electric guitars and some plastic box keyboards. Same goes for most light dimmers too. Its the musician's problem - not your problem. ..... Phil |
