Hello.
I bought Sony M-10 recorder and Soundprofessionals MS-TFB-2 binaural mic.
www.soundsurvey.org.uk sayed to me that in-ear binaurals are not good for quiet ambience recordings (and Rode NT4 or the Audio Technica BP4025 are much better).
I think it is because of high noise and small sensitivity of MS-TFB-2. Also he recommended to me to buy battery module even if I dont want to record loud sounds.
So I think that better to buy Preamp. It will solve two problems in one module - will decrease noise of my binaurals for quiet recordings and will do the job of battery module.
I found that preamps are expensive thing. So I want to find the most cheap one.
I found two solutions:
FEL BMA2 for 160$
http://www.felmicamps.co.uk/products/felbattpreamp.htmlChurch Audio preamps 140$ - 180$:
http://www.church-audio.com/viewcategory.php?groupid=0any other solutions??
My trouble. Is that my friend bought MS-TFB-2 and Church Audio preamp and CA-14 microphone. And he sayed that Preamp work good with CA-14. But when he connect this preamp to MS-TFB-2 he hear some crackles and distorsions. So I think this is because mic & preamp & recorder
--> must be attenuated <--. Maybe my friend hear distortions because CA-14 and MS-TFB-2 have different impendance and CA preamp attenuated to CA14 but not to MS-TFB-2?
How to make right selection of preamp so it be attenuated?
And what the cheapest preamp I can buy in my situation? I need preamp wich will power my microphones and will be attenuated to MS-TFB-2 and Sony M-10.
another problem is I dont know impendance of MS-TFB-2
Sony M-10 have 22kOhm on Line input
