dex Otaku Posted November 29, 2005 Report Share Posted November 29, 2005 Just a little demo. The purpose here is to show what can happeen when recording with either a remote plugged in or when using the AC adapter.Recording conditions:* RH10 HiMD recorder in HiSP mode, AGC on* SP-TFB-2 microphones and Sony ECM-MS907 mic* RM-MC35ELK one-line LCD remote for two [remote and mic cables run in opposite directions, cables not crossed]* AC wall-wart used for two [JP model "universal" adapter]* some editing done to clip my silly speaking, but no processing was usedConditions of downloading these files:* Don't play from my server. Download once, then listen. * Be patient. Upstream bandwidth is limited.The files: [lame --alt-preset standard mp3s]RH10 with SP-TFB-2 mics and RM-MC35ELK remoteRH10 with MS907 mic and RM-MC35ELK remoteRH10 with SP-TFB-2 mics and AC adapter plugged inRH10 with MS907 mic and AC adapter plugged inAnd yes, that's my voice.

greenmachine Posted November 29, 2005 Report Share Posted November 29, 2005 May i begin the discussion with an off-topic question: Why does the right channel of the TFB-2 recordings sound so dull? Is it caused by mic placement?I didn't know that you can avoid hum when using a powered mic in an AC powered recording by the way. Thanks for that.

Christopher Posted November 29, 2005 Report Share Posted November 29, 2005 Why not put these in the Gallery and link them accordingly? I'll take a listen when I get home. Quote Link to comment Share on other sites More sharing options...

Is it caused by mic placement?I didn't know that you can avoid hum when using a powered mic in an AC powered recording by the way. Thanks for that.With the remote recording, the mics were not in my ears, rather they were set on a soft surface with the elements facing up. With the AC power recording, I was holding them up in my hand, and one was likely facing away from me. Why not put these in the Gallery and link them accordingly? I'll take a listen when I get home.Um - because I can't? I don't have permission to do so. Or so I thought. Quote Link to comment Share on other sites More sharing options...
greenmachine Posted November 29, 2005 Report Share Posted November 29, 2005 I just did the same test with electret microphones similar to the BMC/TFB-2's. It made no difference if the mics were powered externally (via battery box) or not. The static / hum was still present in the recordings. Sony mics must have some kind of built-in noise reduction design, don't they? Quote Link to comment Share on other sites More sharing options...
