2. 2-Inputs to 1-Output (2X1) Mode:
In this mode, you connect two audio sources (e.g., a laptop and a mobile phone) to the two input ports (labeled 1 and 2), and one audio output device (e.g., speakers) to the common output port. You can then switch between these two audio sources to play through the single output device.
