This is an XLR audio source selector, primarily used for manually switching audio input/output channels during live performances, recordings, or live streaming. It is a completely passive, power-free manual switcher, requiring no batteries or external power supply. Plug and play, it offers high stability and is suitable for scenarios requiring simple and reliable audio routing. Supports bidirectional use: 5 inputs + 1 output, 1 input + 5 outputs. Functions: Input Interface: `XLR 6.5-IN` (Supports XLR or 6.35mm audio input) Output Interface: 5 XLR outputs, labeled `XLR-OUT1` to `XLR-OUT5` Channel Selection Knob: Central gear-shaped knob, selectable from 1 to 5, corresponding to switching the input signal to different output channels. Mute Function: When the knob is in the `MUTE` position, all outputs are muted, cutting off the audio signal. Signal Flow: The circuit diagram on the panel clearly shows the path of the input signal after selection by the knob, distributed to the corresponding output channel. Use Cases: Live Sound Reinforcement: Quickly switch between different microphones or instruments to the main output. Recording Studio: Select different audio sources for multi-track recording. Live Streaming/Podcasting: Flexible switching of microphone, background music, and other signals to different output devices.
