The UMA-8 is fitted with 4 control switches on the top side of the module with the following use:
SW1: Bypass/activates all microphone processing. The processing is active when the application starts.
SW2: Mic monitoring enable/disable. Enabling the monitor allows the microphone signal to be directly
monitored on the I2S data 1&2 out; Disabling allows audio playback from the host i.e. normal USB DAC. The
monitor is disabled when the application starts.
SW3: Manually rotate beam direction to one of the 6 microphone direction. The beam direction is shown by the
LEDs.
