ANC 750 and USB-SA

[system: Dell Inspiron 530, Pentium E2200 2.4 GHz, 4 G RAM]
Hi, I hope this question makes sense. I usually do WSR with input via an Andrea Supermax array and no output monitoring. But sometimes (as when I need to hear pronunciation of new words or when I'm listening to something else), I'll plug an ANC-750 into the USB card's output jack. This generally seems to work OK. But I'm wondering, Does plugging and unplugging the headset output jack reduce the SR accuracy? It sometimes seems to, but I can't be sure. I have found, though, that if I unplug & replug the sound card itself, the SR takes a while to  come up to snuff. Would changing the output have the same effect? - ed

That is why we built into the WSRToolkit the Tune Microphone feature.   Also, the microphones you are using use completely different technology. The Superbeam which we consider an inferior microphone to the ANC-750, has a stronger pickup signal because it is further from your mouth. You require 2 different volume level settings if you are going to use each. Try running Setup microphone for each. As mentioned, the settings may fluctuate due to a fault in Windows Audio.   Marty

Thanks or the reply. I've not used any other SR than WSR, and never thought the audio levels to be a problem. Tunig the mics as you suggest works fine for me.

Your comment about the Superbeam is interesting. With training I've found it really accurate (again I don't have much experience with different rigs). I usually use it 'cause my place is generally quiet & I like not beeing encumbered by cables. But once in a while I'll plug the ANC-750 headphones (not the mic) into the USB-SA. I was just wondering if putting that load on the output of the USB-SA could have an effect on the input. It probably doesn't, but I'm curious, since changing the *input* (the mic) clearly does degrade the performance of a profile. I also recall noticing that with the ANC-750 diving the WSR through  the mainboard audio (rather than through the USB-750) the recognition got degraded every time I unplugged the mic. Maybe that was before the WSR had been sufficiently trained. In any case, WSR is certainly cranky at first. After running for a long time, it's certainly much better. - ed

Thanks for the help, Marty. I think my posts complicated a simple question. Being confused by the mention of "adapters" on the Andrea website, I was concerned that the ANC-750 might not be compatible with the USB-SA. Evidently it is, and all's well. - ed
