Mic Akg680 Bl - Can't Hear My Voice Options

[kankan]

Hello,

I just bought a AKG C680 BL Microphone (Jack stereo Native and XLR adaptator) to record my voice under Windows.



As i plug the microphone, i can hear some noisy sound but after i can't hear my voice at all... (i have to scream in the microphone to hear a little of my voice...). It sounds like there is an amplification problem. I also plugued it in my Osprey XLR card , but stil no hear voice at all...

Before sending the microphone back to the vendor, i would be glad to read some specialist advises

Hello

It looks like you miss the preamp in between, the level of the mic is kept low so… Does your soundcard/interface has a Pre? I've had a look at Osprey interfaces and none has, the only one with XLR accepts Line level input, there's not preamp as far as I've seen and you need one.

Oh i see, merci lepetitmartien

What do i need to Preamp the signal ? Do i need to purchase a specific sound card ?
I am totally newbie regarding sound systems. I plan to use this microphone for videoconferencing > the mic will be placed on a rectangular table ... this microphone was supposed to do the business ... i am a bit confused.

Thank you for your answer.
