I've had my VR setup a bit out of sorts for over a month now due to my HS2 upgrade. Spent some time last weekend getting everything back in order and the new server racked up.
In the process, I made a few recordings that better demonstrate the noise cancelling capability of the Gentner AP800 mic mixers. This is an old thread that has some recordings, but I think the new ones here are a better demonstration of how well the device works:
First recording made using my notebook's "el cheapo" built-in mic. The notebook was placed on a desk against the wall where the Crown MB2 mic is installed. The music and TTS annoucements are coming from speakers built into the opposing wall.
Bad Company is blasting on the speakers much louder than I would normally listen to it (to the point the notebook mic is distorting), and I'm standing in the middle of the room (12' x 13') speaking VR commands. I think you'll agree that in most cases it's difficult to hear my voice commands over the tunes...
Voice commands issued:
What time is it?
What's the date?
Check the doors?
Please standby (my ignore phrase)
Note: The music in this recording is automatically ducked (lowered) during the TTS announcements and then slowly ramped back up by a Biamp SPM723 pre-amp:

This next recording is exactly the same scenario, but it demonstrates what the PC sound card "hears" on the mic input used for VR. As you'll see, my voice is heard clearly over the loud background music and the TTS responses which are also cancelled using the AP800 are barely audible!

I know a number of members here have recently purchased AP800's or are actively bidding on them... hopefully this is some incentive to win some autions and get them hooked up and working!
Cheers,
Paul
