[AG-TECH] Equiptment ideas?

[Jason Bell]

G'day Matthew

 

Can I suggest you have a look at the chat150, as I have used it within
the range of 3 meters and I find it works reasonably well.  Obviously
you will have to adjust the mixer settings to increase the gain, but I
think it might be acceptable.

 

The other benefit of this device is that it has 3 microphones for
pickup, which assists with picking up audio from different directions.

 

Obviously an open area is more difficult and that having the mic on a
table which allows the audio to absorbed and picked up better will
assist.

 

Anyway, I guess it cannot hurt to try one and if it doesn't work, use it
for another application.

 

My 5 cents worth.

 

Cheers,

Jason.

I have also considered USB based devices, such as the iChat, and the
Duet. They do not have a very good range for microphone pickup from my
experience with them, they are good for very close range (~ 4 ft, after
that it doesn't pick up anything very well).  Unless do you know of a
USB microphone that has a better range, and gain, so it can pickup sound
decently in an open area from more then 6-8 ft?

Did you consider the USB mics, Duet PCS or ClearOne iChat series? Each
mic does its own EC.

	Hello all,

	                One of my current projects is a public AG
kiosk-like setup, in which people will be able to walk up to the node,
choose a stream and start to talk directly with that stream. The area is
about a 12' X 12' square area, with drop-tile ceiling, it will consist
of 1x HD camera, 1x DV camera, 2x 52" HD LCD TV's, 1x high quality
microphone, some sort of directional speakers, and an echo cancellation
system.  It seems that I would only need one microphone input for this
project. However I have mostly worked with the ClearOne XAP400, which is
a dual line-in echo cancellation system, and the XAP does not seem to
come in a single line-in version. Is there some other echo cancellation
unit that people would suggest for a setup like this? Or have I missed a
single line-in version of the XAP? Also any other suggestions for the
node would be nice to hear, in case others have ideas that haven't been
thought of, or others are thinking of building a node such like this.

	 

	 

	As always all help is appreciated!
