How to solder any electret capsule to the TA4F connector of XD-V70L?
by Wil_Riker on 2011-07-21 05:01:42

Hello,

I just registered for the following question that cannot be answered completely with the FAQ: How do I have to solder a standard electret capsule to the TA4F mini XLR connector, so that the the microphone is powered by the beltpack transmitter of the Line 6 XD-V70L system?

I know the pinout from the FAQ (1 shield, 2 V+, 3 signal, 4 Z) but how to connect the shield and signal wires of the capsule to the pins?

Shield on 1, signal on 3 with bridge to 4 is obvious - but do I have to connect/bridge any of the other pins (e. g. 2 to 3)?

Thanks, with kind regards,

Wil Riker

Sorry for my bad English, I'm a native German speaker :-o

Hello Number 1

Does your mic have only a signal wire and a ground?  Usually there are two wires and a ground.

In this case you will need to add a pull-up resistor and a cap to bloc the DC.  This will require some experimentation to get the best component values.  Does the mic manufacturer have a wiring scheme suitable foir connecting the Shure brand wireless?  Ours would be the same.

Add the pull up resistor (10k is probably a reasonable starting value) from pin 2 to the hot wire in your mic.  Short pins 3&4 together and add a cap (10 uF is a good start) between them and the hot wire of the mic.  Connect the ground wire to pin 1.

Hello dboomer,

it is a standard electret capsule with only one signal wire plus ground/shield. I successfully got those capsules working with Sennheiser- (signal = tip, ground = shaft), AKG- (TA3F: ground = 1, signal = 2+3) and Beyerdynamic- (TA4F: ground =  1, signal = 2, 3+4 bridged) bodypacks without using any resistors or capacitors. Probably there's a quite similar easy way to match the capsule to the XD-V70L bodypack?

Any other ideas or does it really only work with additional capacitor/resistor?

You can probably get away without the capacitor, try it and see.

I just use a 2k2 1/8w  and standard Sure connections

Hi boswell2007,

that means: 1 = ground, 2 = resistor = signal, 3+4 = bridge

Or do I need an additional connection between signal and one of the other pins instead of the capacitor from dboomer's scheme?

Thanks,

Wil Riker

Hello again,

thanks, I'll try it with the second scheme...

Hello guys,

I'm back to report that boswell2007's second scheme works fine with my eletret headset. I used a 3k3 resistor because I didn't have 2k2 .

Thanks for your support .
