I have the Q900 V4 with firmware 3.4.1.
The MA X9814 mic amp in my project has AGC. I did not choose this one, but it was sent to me, because the other one was not available.
With the AGC there is ALC but the gain raises up to 20 dB. So everything in the room can be heard after the release time while not speaking into the mic.
