Hello, Colleagues, My G4 desktop and my neighbor's G5 desktop does NOT have a built-in mic. Okay. So I need an external mic in. On the back of both machines is an Audio In Port. But what impedance does it like??! I bought a $20 Radio Shack multi-media headset. It works fine a (hush) PC, but doesn't work on either of our Macs? Whazzup with that? As Freud asked of women, I ask of Apple: "What do you want?" Do any of you use a headset? I want to use it with iChat, Skype, and to record a few sound bytes for various projects. Hi-fi in these cases not needed. Do I have to buy an adapter? Something like a phono pre-amp? Wha-? TIA, Lanny -------------- next part -------------- An HTML attachment was scrubbed...
