Re: [AG-TECH] Tabletop-Room mic with integrated echo canceling

["Enrique Terrazas" <Enrique.Terrazas@xxxxxxxx>]

Fred,

We ran into this same when we first started using the ClearOne  
AccumicPC with a Dell XPS at UCSF.  We noticed that the sound level  
according to RAT was very low.  There is an advanced sound setting  
where there is a check box for a "20dB boost" for the mic input (I  
don't remember the exact number for the boost as it's from memory).   
Clicking on this check box increased the sensitivity of the ClearOne  
tremendously, and now they would great for us.
