Where is this hiss / buzz/ sizzle coming from? Help please.
What do you think this noise is from? I’m a voice talent, have had my studio for 7 years now. Just this past week or so, I’m been increasingly bedeviled by a problem with noise – it sounds like a loud sizzle. I noticed that it was much worse when I used my ART MyMonitor headphone amp. After some testing, I found that if I didn’t use the headphone amp, the noise mostly went away with some mics. (Note, the headphone amp might be a red herring in this story). I also found that a certain new mic I just had modded is MUCH more susceptible to the problem, whatever it is. Changing the mic cable to a Mogami Gold did not help. Here is a file with 3 sound clips, all using a solid-sate Speck 5.0: Mic “A” *outside* my booth, with a very short mic cable (I hear fan noise but NO hiss); Mic “A” inside my booth (tons of hiss); and a Rode NTK inside my booth (NO hiss - the first few seconds were recorded with the door closed before I got it, and there is little to no noise). I’ve noticed that my Studio Projects CS5 also does not have this noise issue when in the booth. Here is the sound file: https://www.onlinefilefolder.com/4sUnfuKYaNiHUT
If the mic isn't the source of the problem, then why would Mic
” have this terrible noise inside the booth, but not the Rode or CS5? And if the mic IS the source, then why is it fine outside my booth? I'm perplexed. More background: I have not made any changes to my studio set-up lately. No other new equipment, aside from the modded mic. I’m using a Furman Power Conditioning strip for my equipment. In my sound booth, the XLR cable and headphone cable pass through a hole at the bottom of the booth, the same hole where a power cable for a Belkin SurgeMaster 6-plug outlet goes.
Now I know that can cause problems. That's why I had the power cable wrapped in aluminum foil. Up until now, since I got this outlet a few years back, I have not had any problems. If this IS the cause, I don't know what could have happened to it so that it suddenly brings this buzz. I have just shielded the power cable with more aluminum foil, and moved the power cable up to the perimeter of the booth, as far away from other cables as I could – and the hiss/buzz is STILL there! Arghhhh.
Thanks in advance to anyone with some ideas for solving this problem!
