Mic Connectors (front-panel connectors)

I've got an audigy 2 zs card, and it has no spot for these connectors - so I'm just going to rip off the connector on these cords, tie them up to a spare male jack, and plug it into my audigy card's mic jack (and do the same for headphone jack)

that will work -

problem is, I don't know what the words on the connectors mean. what I need is MIC+, MIC-, Ground, as per this mic jack diagram (ignoring the speaker stuff, it's not the right adaptor but I assume it's the same positions, I can't imagine why it wouldn't be)

my connectors are as follows:

Mic Data
Mic VCC
Grnd
EAR L (white)
EAR L (black)
EAR R (red)
EAR R (black)

I'm assuming I won't be needing the EAR stuff - what I need to know is:

what the heck is Mic Data? What the heck is Mic VCC?

Have you gone through this http://www.devhardware.com/forums/showthread.php?p=15584.

The pins you are talking about sound like a digital mic in not an analogue mic in (as would be on the front panel of a case), I would do some more research before you go plugging things into that, you may end up damaging the board.

while thats good advice and I will look into that, I don't see why anythind should get damaged. there's no circuitry or anything - just a female connector tied to some wires.

ps, that link is to the 'local pub' and some rather off topic posts. am I missing something?

You are talking about driving an analogue mic signal into a digital input signal. Without knowing the input protection protection built into the circuit it is hard to say what it can tolerate.

Generally speaking if you tie a digital input to gnd or digital Vcc or even something in between you should not have a problem, but since you are not doing that here and are connecting an anologue input (not reference to the digital power rails) there is a chance it could cause damage.

I don't think I've explained the situation too well....

I have an analog mic and and analog mic input jack on my card. I also have a seemingly digital mic input jack on the front of my case. all I want to do is connect that input jack to a spare cord with a male jack at the end and plug it into my card. that way I can use the front panel mic jack.

I have no digital equipment. (aside from the input jack, but it is only a jack and nothing more)

Without getting to technical lets just say yes (there are times - not this where that would not apply).

And it makes sense now as well. Some newer cases have a digital audio front panel connector to match the newer MB's.

You could check it with a multimeter but chances are it should be OK.
