Hi HomeRecording.com Forum Readers,
I have an issue with my recording space and I hope you can hep me diagnose the problem, and maybe even suggest some solutions.
The problem is that I am picking up hum or a "buzz" into my system. The sound is not audible to ears, only through the recording equipment, which has me assuming that this is electrical interference. Overall, the sound is variable, so some days it's unnoticeable, but one occasion has ruined a day's take. During troubleshooting, the sound is louder when the microphone is nearer to "the source", or orientated in certain directions.
The source is the ceiling in the basement. There are pot lights installed which shouldn't be on any dimmer switches (the wall only has I/O switch), and when the lights are off, the sound persists. We've also been able to recreate the problem from the floor above by putting the microphone closer to the floor.
The sE v7 picks up the hum louder than the AT-2040. I wonder if it's a shielding issue or a difference in their output impedence.
Equipment chain:
sE v7 or Audio-Technica-2040 or Rode NTG-2
6ft XLR cable (I'm 90% sure shielded)
Rodecaster Pro mki
Recording media (micro SD card) or Monitoring headphones
I've attached a short recording of the buzz the variation in the amplitude of the buzz is me moving the microphone around (if the position is static, the sound is consistent). Treatment on the recording is 4:1 compression and gain increase.
What do I need to do? Do I need to get an electrician and find the source? Can I make a makeshift barrier with coil springs from an old mattress and several rolls of aluminum foil?
Thank you,
Steve
