following the steps of Keith in
http://voxcommando.com/forum/index.php?topic=1757.0I am starting this thread to document my setup using Gentner Clearone XAP800, and to discuss obstacles and solutions ...
this should apply to AP400, AP800 and XAP400... these are extremely advanced matrix mixers ... at the time of this post they are flooding ebay .. you can get one from 25$ and up (I saw it for more than 1000)... I believe the reason is that in US, these are being phased out from schools or government setups to be replaced by newer models (according to one reply from ebay seller)...
if you are planning to implement a permanent open-air mic at some point, I highly recommend that you grab one or 2 (depending on how many input signals you need - more on that later) .. boundary mics can be found on ebay for reasonable prices as well (I managed a deal of 4 for 60$ including shipping)... the irony, the various cables I am buying to pass through my apartment are more expensive than the device and the mics
the reason I decided to go for these ...
1. those mics are crazy sensitive ... they can hear me whispering from about 10 feet (3m)
2. multiple active mics (up to 8 in XAP 800) + 4 inputs line level on one device. Devices can be chained to get even more !!!
3. adaptive noise cancellation, which is doing great in my initial testing
4. echo cancellation ... make your music, tv, pc ..etc. go through the device and it can filter it out from what it hears through the mic... so VC won't react to speech coming from a speaker ...
5. with 1 or 2 devices and multiple sound cards (depending on number of rooms and stereo or mono signal) these devices can double as audio routers ... meaning VC can send music on sound card 1 to bedroom , and radio on another to kitchen, while watching Blu-ray 5.1 in the living ... or send the music to all rooms ... that applies as well to VC responses ...
status and control ports ... these can be used easily to create control panels around the house to trigger certain setups (scenes) ... those can be routed back to PC through com port
6. and a very important feature, all the features of the device can be controlled through com port by PC
7. gating ... means VC can now the command from which room (although one guy blogged that he disabled this feature, but I believe right configuration can make it work)
