mozart999uk Posted February 26, 2009 Share Posted February 26, 2009 Hi. Can anyone help me out with this? I have the CPC MP33750 lavalier mic and I need to solder the ends to a shure TA4F connector. The pin out is : PIN 1 = cable shield/ audio return/ bias returnPIN 2 = +5V DC BiasPIN 3 = audio input PIN 4 = 20kΩ resistor to ground jumpered to pin 3 Any ideas? Thanks Matthew Link to comment Share on other sites More sharing options...
Pete Alcock Posted February 26, 2009 Share Posted February 26, 2009 Hi Matthew, Screen of the mic goes to pins 3 & 4 linkedCore of the mic cable goes to pin 2 Leave pin 1 disconnected. This is how I have mine connceted and it wotks with all the 2-wire electret mics I've ever used. Pete. Link to comment Share on other sites More sharing options...
Sound Man Posted February 27, 2009 Share Posted February 27, 2009 Mathew The last time I wired up a connector for the Shure transmitter I did it as shown in this diagram. http://i588.photobucket.com/albums/ss328/Sound_Man_Photos/MICTA4F.jpg The reisitor needs to be small in size to fit inside of the TA4F connector.

pisquee Posted July 9, 2009 Share Posted July 9, 2009 Both of the solutions offered here seem to contradict each other.Now I'm more confused than when I came to this thread. Link to comment Share on other sites More sharing options...
dynamicvisions Posted July 13, 2009 Share Posted July 13, 2009 I have a similar problem, I have a Sony ECM77 that I am wanting to solder to a 3 pole locking jack for a Sennheiser EW300 G2 unit. Any Ideas? Trantec's website is full of wiring diagrams but Sennheiser is useless. Link to comment Share on other sites More sharing options...
Nid Posted July 14, 2009 Share Posted July 14, 2009 While we're at it... I am looking for wiring diagrams of guitar cables for:1. the Shure TA4F (LX)2. the Sennheiser 3.5 (EW100) Any info will be greatly appreciated, N.Webber Link to comment Share on other sites More sharing options...

Shure TA4F - Connect as follows - PIN 1 = cable shield, PIN 3 = audio input, PIN 2 & 4 = not connected2. Sennheiser 3.5 - Connect as follows - Sleeve (barrel of plug) = cable shield, Ring (line input) = signal, Tip (mic input) = not connected Hope this helps David Link to comment Share on other sites More sharing options...

Ian Fish Posted October 27, 2009 Share Posted October 27, 2009 On a similar theme, I have a CPC Lavaliere mic, MP34153, which I'd like to get working with a Sony UTX-B1 transmitter pack. A search for suitable/relevant wiring diagrams or adaptors brought me to this page and I'm hoping somebody can explain how to re-wire/adapt the CPC mic for use with the Sony transmitter. As fas as I know, the CPC Mic is wired for Sennheiser transmitters. Thanks for any help ! Link to comment Share on other sites More sharing options...
Sound Man Posted October 27, 2009 Share Posted October 27, 2009 Searching on the internet all I have managed to come with is the following Link. David Link to comment Share on other sites More sharing options...
Ian Fish Posted November 10, 2009 Share Posted November 10, 2009 Thanks Sound Man - it looks like it's just a case of switching the tip and ring around then. I'll see if I can make up a short adaptor cable, rather than stripping off those tiny wires and attempting to re-solder ! Link to comment Share on other sites More sharing options...
AndyL Posted November 10, 2009 Share Posted November 10, 2009 I am looking for wiring diagrams of guitar cables for:2. the Sennheiser 3.5 (EW100) 2. Sennheiser 3.5 - Connect as follows - Sleeve (barrel of plug) = cable shield, Ring (line input) = signal, Tip (mic input) = not connected Nearly, but not quite. For guitar input on Sennheiser 3.5mm three pole jack connector for Evolution, inc. G2 and G3 - Connect as follows - Sleeve (barrel of plug) = cable shield, Ring (line input) = signalTip (mic input) = short to sleeve. Similarly when the mic input is used the Ring should be shorted to the sleeve. Shorting the unused input to sleeve is especially important (essential) with G3 pocket transmitters. P.S. I have no control over the Sennheiser Web site...And the relevant information is contained in the user manuals. A concurrent post has been automatically merged from this point on. Both of the solutions offered here seem to contradict each other.Now I'm more confused than when I came to this thread.That is because there are two modes of use for electret mics, two wire and three wire. With the Shure connector arrangement and various other similar multi pin connectors both are possible because there is a separate audio input, DC supply and ground connection available, and in Shure's case they have even provided a bias resistor. On others, such as most Sennheiser transmitters, there is no mic level AF input that doesn't have a DC bias superimposed on it so you have to use the two wire method. I have yet to find an electret mic that can't be used in 2 wire mode. There are some that can't be easily wired in 3 wire mode though. There is a very handy resource on this subject on the Shure web site at: Shure Tech Notes Link to comment Share on other sites More sharing options...
