A microphone is connected to the TE40 through the TE40's RCA input port 2. A microphone array is also connected to the TE40. When the mobile phone plays music over the microphone, an audio freezing problem occurs.
Music is played locally. The microphone picks up the music sound onto the TE40. The AUDIO IN echo cancellation function is enabled. In this case, you need to enable the music mode and disable the echo cancellation function to achieve the optimal music effect.
The echo cancellation function suppresses the music mode, causing audio freezing of the music.
