dreynolds Posted May 11, 2005 Report Share Posted May 11, 2005 Hi;I'm trying to record quiet music (playing silver flute) and I have to twist the recorder and/or mics to try to quiet an annoying hum. It works best with the mics touching my skin, but that is too loud to record properly. Is there a way to kill the hum without touching me so I could record from, say, across the room?thanks dr Quote Link to comment Share on other sites More sharing options...
ozpeter Posted May 11, 2005 Report Share Posted May 11, 2005 Sounds like there's a wiring fault, or are you placing the equipment near something generating hum like a computer monitor? What precisely are you using (mic & recorder)? Quote Link to comment Share on other sites More sharing options...
A440 Posted May 11, 2005 Report Share Posted May 11, 2005 Could there be a loose ground wire in the mic? Or are they humming because they don't know the words? javascript:emoticon('')smilie Quote Link to comment Share on other sites More sharing options...
atrain Posted May 11, 2005 Report Share Posted May 11, 2005 sound like it's got a grounding problem if it goes away when you're touching it. Quote Link to comment Share on other sites More sharing options...
Wedge Posted May 11, 2005 Report Share Posted May 11, 2005 When you say twist the recorder and/or the mic, what do you mean exactly?You haven't got one of those tiny plug-in mics have you, that just stick out of the MD? They do tend to pick up noise of the MD itself - or so I have been told. Quote Link to comment Share on other sites More sharing options...
dreynolds Posted May 12, 2005 Author Report Share Posted May 12, 2005 I noticed this hum with two different sony recorders and two different mics, one powered and one not, most recently with a sony 707 recorder and a tiny condenser mic on a 3' cord, I'm guessing it's some kind of grounding issue. It's not the recorder operating. There is a soft but audible hum unless the mic is near my skin, and I also get a slightly louder hum through the microphone if the recorder is plugged into the sony 3v adaptor. The hum comes and goes, but if the mics touch me, the hum drops away entirely. I notice it more in my computer room, even if I completely shut down all the electrical devices in the room. Maybe some kind of grounding issue. Anyone know? Quote Link to comment Share on other sites More sharing options...
A440 Posted May 12, 2005 Report Share Posted May 12, 2005 The AC adaptor is known to introduce hum. Battery life is so good on MD recorders that even one fresh generic AA battery should get you through a few hours of recording, so skip the adaptor. I never noticed a hum on my MZ-N707, but I didn't record a lot of acoustic music on it. What kind of mics are you using? Quote Link to comment Share on other sites More sharing options...
