I'd like to ask the original question a little differently -- is "full duplex" an accepted phrase in the industry for this capability? It seems a definite migration from the more traditional meaning of full duplex, and I think we (everybody -- consumers, producers, alike) would benefit from using some different terminology, which would include the term "mixing". If full duplex is already an accepted industry term for this capability, that's unfortunate (IMHO). BTW: Re: "Full duplex allows many things through 2 independent channels" -- those many things ususally mean send and receive simultaneously. The capability being described here is to send (to the speakers) multiple things simultaneously on one of the channels, which is more of a mixing function. (I have no idea whether "ordinary" sound cards can also accept sound input from the mike and send that to the computer simultaneously with transmitting sounds from the computer to the speakers, nor whether, if not, a "new" "full duplex" sound card would have that capability. PS: I know in the above I am mixing two concepts of "channel" -- one being where the two channels are in opposite directions (send vs. receive), and one where a sound device, like a mixer, may have a large number of channels. Don't know if I've helped at all -- I guess I'm just trying to avoid more confusion of terminology. Maybe someone who knows more about those cards and that capability can provide more information. In the end, I guess all the sound comes out of one set of speakers, so by then, the signals are mixed. (Even if you have stereo or some five channel surround sound.) regards, Randy Kramer
