It ensures users a better communication experience by mechanisms of AGC (automatic gain control), AEC (automatic echo cancellation) and ANS (automatic noise suppression).

Integral signal processing includes a dynamic AGC (Automatic Gain Control) circuit, a stereo crossover and signal limiting for the prevention of a distorted signal to the internal amplifier.

Wideband amplifier, realized by the technology of automatic gain control (AGC), is used widely in radar system and other correlative electronic fields.
