Need assistance with Neutrik combo connector and Phantom power

[tmarra]

If I recall the Neutrik Combo connector brings ALL the connections out seperate on the back. That is the 1/4" inputs are not connected to the XLR inputs. It's up to you how you want to wire them.

Tony,

Thanks for your reply. You are correct. To use them as I want I would have to bridge the TS/TRS and XLR contacts.

The issue is dealing with phantom power and if there is any safeguards I can wire in to avoid accidentally sending phantom down a line signal.

Just bridge your inputs on the other side of the mic input blocking caps that are already on pins 2 and 3 of the XLR mic input.

Ooops. OK so I re-read you post and I'm guessing you want to do this external to the MixWizard. So that means you need to install some caps between the Mic XLR and Line TRS on your external panel. I think 100/63V should work fine.

Tony,

Thanks ! That's exactly what I'm looking for. However could you be more specific? are we talking 100pf/nf? Are we talking about polarized caps? Which way? And this will keep phantom going to XLR, but will stave it off from the TRS?

Could I just bridge the XLR and TRS connections with caps instead of solder/wire?
Caps would only go across form pins 2 and 3 right? Remember this is all one connector, just with discreet pins I beleive.

Thanks again.

That would be uF as in micro-farrads. Since phantom power is +48 on both signal connectors, you should put the + side to the board and the - side to the line. You may want to bypass the big electrolitics with a polyester or polypro cap of about 1uF (this will not be polarized.

That's it just like tiny said. You could put them right on the Combo connectors. Just make sure that the Electrolytic caps are larger than 48V (that's why I mentioned 100 MicroFarads @63Volts) or they will explode on you. stike
