The AI-Micro allows you to configure how the audio from the input channels is routed to the output. There are three different channel modes, ‘Merged’, ‘Split’ and ‘Stereo’, which are suited to different microphone setups.
In ‘Merged’ mode, the input signal is routed to both the left and right channels of the output, which is ideal if you are just using one microphone. In ‘Split’ mode, input 1 is routed to the left channel of the output and input 2 is routed to the right channel, which is ideal if you are using two microphones. ‘Stereo’ mode is ideal when you are using a stereo microphone; the left and right channels of input 1 are routed to the respective channels of the output to ensure you retain the microphone’s stereo image (input 2 is disabled).
