I've read about mics gain adjustment, but i am unsure about what is best about gain from "Rx from Codec" input (it is better to send the loudest level from PC audio, so I will have a strong signal on the XAP input? or that doesnt matter?)
I'll think about NOM parameter, that is something i missed to think about. ----- Original Message ----- From: <pei...@maine.edu> To: "Natalia Costas Lago" <nata...@cesga.es> Sent: Monday, December 27, 2004 9:47 PM Subject: Re: Fw: [AG-TECH] XAP setup > Natalia, > The XAPs (I use XAP800's in other projects) are capable of full > duplex with AEC. > You might start by checking what your AEC reference for the > microphones is comprised of.
