pyer75 Posted June 10, 2014 Report Share Posted June 10, 2014 Hi everyone, I am looking for a cheap/diy solution to power 2 neumann KM184 out of 9v batteries. The goal is to ste up a wireless ORTF couple. The couple is going to remain on stand, so I don't need a compact/superclean box, but I need a sound quality comparable to this : http://www.areitec.fr/areitec-pico48-phantom-power-adaptor-zaxcom-wireless-produit-395.html even though I can't afford an audio transformer. I have 2 lectrosonics Smqv transmitters to feed but according to Lectrosonics datas I can't draw sufficient current from it. I recently used one of those gadgets http://www.bhphotovideo.com/c/product/840641-REG/IK_Multimedia_IP_IRIG_PRE_IN_iRig_Pre_Microphone_Interface.html , sounded like ok I guess I could solder a TA5 plug instead of the 3,5mm jack. Someone ever tried ? For a complete diy solution, my first google prospections lead to that kind of things : http://www.geofex.com/circuits/+9_to_33.htm But I lack the advice of professional ears ! thanks in advance, Pierre Quote Link to comment Share on other sites More sharing options...
Jim Gilchrist Posted June 10, 2014 Report Share Posted June 10, 2014 You might be better off buying an existing product. Denecke builds a dual 48 V. supply. Here's a link: http://www.atreid.com/index.html?menu=1430&id=1430&entree=3&c1=474922&c2=&produit=6028 Best regards, Jim Quote Link to comment Share on other sites More sharing options...
studiomprd Posted June 10, 2014 Report Share Posted June 10, 2014 Bon jour, hi, and welcome... in spite of having name brand equipment, you seem to be lacking in some basic audio knowledge, shopping at BH is another clue, though perhaps it is a translation issue. Lectrosonics SMVQ transmitters cannot power Neumann KM microphones, or any microphones requiring industry standard microphone Phantom power. Jay Rose has some excellent books at www.dplay.com.... or you may search the internet: <I gave you a clue!> Quote Link to comment Share on other sites More sharing options...
