I've never tried this, but it seems like you'd get some type of squealing feedback issue doing it. Even through a mic is a receiver of sorts, converting sound waves to electrical impulses, it's also a speaker in a manner of speaking because it works off the same electromagnetic-induction principle. If you hook a mic up the right output port, it can actually be a speaker and you can actually hear audio coming out of the mic's diaphragm, and a speaker can be used as a mic in the inverse way. Of course either way the quality is pretty bad obviously. You can do this with speakers or headphones, there are dual "Y" adapters for headphones because they are an output and there's no issue with output going to two devices. But with input it's possible that one mic's input could bleed over into the other mic's output going down the line into the input jack causing feedback, and I don't just meant acoustically (which can be avoided by making the distance between the mic's large), but electrically as well. You can always try it, but after recording a few seconds stop and listen to the playback to see if there is any feedback. You can probably use one of the headphone dual Y adapters for this, just make sure the jacks are compatible. This would probably be with a mini 3.5mm jack, and you'd need to consider a mono/stereo adapter in there since headphones are stereo and mic's are usually mono. -Clint God Bless Clint Hamilton, Owner http://www.OrpheusComputing.com http://www.ComputersCustomBuilt.com http://Computer-Hardware-Sales-Consumer-Electronics-Sales.com ----- Original Message ----- From: "Harold Windle" Good morning all. A 'double adaptor'...is such a thing available, which will allow me to connect 2 microphones to the single input point on my lap top computer. If not, is there another way of doing this?
