2. Connect your second audio source to the (IN/OUT) 2 port using a 3.5mm audio cable.
3. Connect your audio output device (speakers, headphones) to the IN/OUT port using a 3.5mm audio cable.
4. Use the '1/2' selector button on the switcher to choose between audio source 1 or 2.

Configuration 2: 1-IN-2-OUT (Switching Audio Outputs)

In this configuration, you can connect a single audio source (e.g., a computer) to the switcher and select which of two audio output devices (e.g., speakers or headphones) receives the audio signal.

1. Connect your audio source (e.g., PC, smartphone) to the IN/OUT port using a 3.5mm audio cable.
