    USB standards say to stay within 5m on passive cable length, though I've done ok with somewhat longer. An active cable would theoretically let you go longer, but it may depend on the cable. The thing about USB audio (unlike USB networking) is that the audio stream is continuous and can never be resent -- if the stream gets broken because anything on the path gets too busy to keep up, then that portion of data is just simply lost (and apparently in your system appears as a big noise spike when it happens).

    OmniMic looks to the computer system just like any USB stereo microphone, uses the built-in Windows USB drivers even. An active extender is essentially another USB hub, something else the main computer has to now manage without losing bits. You might find that it will work smoother with the extender if you turn off all wireless and bluetooth hardware attached to the computer -- wireless/bluetooth can both be time resource hogs and may be keeping the main system from keeping up with messaging from the OmniMic and the active extender.

          I have used a three meter extention from time to time and have not had a problem. I agree, good system.

            Curt,

            So I see you are now using an Omni. I will be interesting in seeing how things go in your measurements with it.
