We were doing recording for my Church choir in our acoustic recital hall. Everything sound good over the monitoring headphone on the TASCAM MD recorder. But the final output was full of noise when we listen it over a large mixer. SO WHAT IS THE PROBLEM???
FYI, we used two Sennheizer condenser mic for the choir, Shure (57?) for piano and Mackie mixer. Was the present of noise due to the reason that we did not use a compressor?
Hope someone could help me with this.

Nov 27, 2002 09:18 am What's a white noise?
In our case, it sounds like an industrial air-con is blowing straight into the mic. But the thing is we can't heard it when monitoring over headphone at the recorder headphone jack.
(Thanks for responding so fast:) )
Nov 27, 2002 09:32 am white noise is....welll...Uuuuuuummmm, white noise, I don't know how to explain it.
for starters have you taken the recording and played it over anything other than the PA system? Like maybe your home stereo or something like that, if it still has noise then we have a prob, if you can't hear it then it is a prob with the PA system.
Nov 27, 2002 11:43 am Ya, we'd tried a Yamaha mixer at our main worship hall. It sound as noisy!
I even tried to get away the noise using some software. But it sound like the track has gone through a 'phaser' effecter after using those noise remover software.
The contractor who did up the sound system claims that it work perfectly!!!
Can a compressor or anything help to prevent the moise? (We intend to re-record the choir.)
Nov 27, 2002 03:27 pm compressor will actually make the noise more evident because it boosts the weak signals. in your case of removing noise i wouldnt try to use a compressor to solve the problem. most likely the problem is in the hardware somewhere. if it sounds like a constant rumble (what you described as the fan blowing into it). make sure that there is no flow of air going into it. or if air is a must try using a popper stopper (20$ at local music store). check the mixer. if youre recording through a Powered PA mixer then noise is going to be there anyway because its not made for recording. the only other suggestion is to remove each mic, and try them out individually to see if any of them are malfunctioning. take small incremental steps into finding out what is the culprit.
Nov 27, 2002 07:05 pm It is very odd that you did not hear it while recording. Using a mackie and a senheiser says that the equipment was most likely quality stuff. White noise is a high frequency hiss if recorded. It is noise that is purposly generated in some buildings to drown out aberent noises. Psychologicaly, it is often impreceivable to the ear. We are used to it. Once aware of it, it can be noted. The only other place per what you have written would be in the connections out of the mixer into the tascam. If the output of the mixer was low and you had to use the tascam to amp up the signal, you may have introduced solid state amp his. Other than that I have no ideas. One habit I have had to develop, and maybe this is just me. I get all excited about recording, so I have to listen to the room dry (no music) for a bit real carefully before recording. Once I start recording my mind seems to focus more on the music than the sonics. I have come home with recordings that had things in them that I did not preceive while recording. Then I listen a week later and hear all kinds of mistakes that I missed the first listening. Especially if I like the music being played and am excited about the piece and want it to be good. I actually do better with pieces that I do not like. I can be a more objective listener to the sonics.
