Dynamic microphone troubles...

Post by Gilbert Walker » Mon May 18, 2009 4:08 am

Hey there!

I just bought an AKG D5 dynamic microphone, complete with cable and 3.5m converter.
I plugged it into the mic hole on my laptop (which has worked for other microphones) and I am getting NO SOUND AT ALL in audacity.
The microphone works when I connect it to an Amp. It works when I connect it to the stereo using the 3.5m.
My inbuilt laptop mic works in audacity...so I can't work out what the problem is!

Thanks for helping!

Do you remember exactly the name of the adapter you bought? I bet it was an XLR to 3.5mm adapter, not a balanced to unbalanced converter. The former preserves the carefully designed balanced, interference rejecting, floating nature of the microphone but is completely useless plugged into a sound card.

The latter abandons all that nice technology and forces the three wire microphone to be two wire by physically smashing the wires together which is precisely what the sound card needs. Does your 3.5 look like either one of these...

...then you probably got the first one. I don't think there is a Radio Shack adapter to dig you out of this. See if AKG has an adapter. A correct adapter will be missing the ring connection in that illustration. It will have just the Sleeve and Tip. Like the bottom illustration without the battery connection. Your microphone does not take battery voltage from the computer.


As a complete aside, you may find that even if you go through all that, the average PC sound card can be pretty dreadful. Noisy and harsh or distorted. That microphone will be an order of magnitude better quality than anything else in the room. Most people also graduate to a mixer or external sound card to do anything with any quality.
