If the reflected signal picked up by the microphone is higher than the level of the signal sent to the line output to your amplifier, that microphone channel has positive room gain. The more positive the room gain, the harder the AEC must work to determine which signal is an echo and which is a local speech signal INDEX Mic/Line Inputs, Line Inputs, Line Outputs Page Page Polycom, Inc Installed Voice Business Group 1725-80098-001-C1720 Peachtree Street NW, Suite 220 Atlanta, GA Phone 800 932-2774, 404
