HC42, A/V in, externe Mikros, rechter Kanal sehr leise

HC42, A / V in, external microphone, right channel very low



Frage von id073897:

Hi,

I have a HC42 with Fingercam for pictures of bike rides. When I connected two external microphones, then the right channel is much quieter than the left. On the camcorder I have tried everything possible s.Einstellungen that brought but noBesserungen. If I taushe the microphones, the effect remains the same, as if the cable is replaced. I have also tried it once with another HC42, same effect, seems to lie s.Camcorders, and not s.den microphones.

With Google I have not found much, except this Thread:
http://www.camerahacker.com/Forums/DisplayComments.php?file=Video% 20Camera/Sony/converting_AIS_to_mic_audio_jack

The thread has nothing to do directly what with my problem, but in about half there is a hint that connected the SonyHST1 Micro, of AIS, one of the two channels from the total signal is somehow extracted: "Left is passed through, and right is created by subtracting the left signal from the combined signal of the center mic. "

Could it be that something similar happens synonymous with external microphones sA / V connector? How then could the problem be solved? I'm not synonymous too cowardly to take even a soldering iron in hand :-)

Gruss,
Gunter



Antwort von carstenkurz:

'd have time to feed through cable test signals. I can not imagine that the camera applies when external supply the same process as the internal microphone. Although, if I understand correctly connected via AIS, then it probably made generally synonymous M / S, and is unlikely to cause your problem. But this need not be all bad - have to keep changing your microphones.


So my MP3 player or laptop with test signals? Connect. Any results from the fact that one page is just stupid as sensitive as the other - then you have to make for external signals with a few resistors a unilateral level matching.

If necessary. with a potentiometer test out the exact value, and then soldered with appropriate small resistors (possibly 1206) in a small cable adapter.

As I said, brings nothing but when you see the M / S coding of AIS can not handle.
