The K3 AGC can be set for varying threshold and compression, so turning
AGC on and off can reveal dramatic differences in signal level.
Recent releases of K3 firmware have an audio limiter that can be set to
limit audio levels when AGC is OFF.
See the firmware release notes or the latest K3 Manual for how to use
the CONFIG:AF LIM feature.
