What is line output, such as mobile phones, MP3 players, computers, CD players, , and electronic instruments (electric guitars, hair dryers, saxophones, electronic pianos, electronic drums, etc.)? The signal strength output by these electronic products is about 0.3vrms to 2vrms;
The microphone input port requires a voltage range of 0.01V-0.1V. If the output signal of the circuit is input, excessive signal can cause serious distortion. This machine can reduce the signal to a suitable size, so that some audio devices can be input to the sound card or speaker interface, causing them to produce reverberation effect. It is suitable for some music playing friends to live stream and record videos.
