1. 4 Way Audio Switcher: Our audio switcher does not need to repeatedly plug and unplug the cable, avoid wearing the socket contact point, 4 ways can input and mix different audio sources at the same time, and can also output at the same time to meet the needs of recording.
2. Perfect Performance: All input and output terminals of the audio splitter are made of elongated gold plated copper, with large contact area, perfect performance and ultra low signal loss, which can perfectly match different styles of audio equipment.
3. Supports Simultaneous Work: In addition to the basic mono switching function, the function of the 4 way audio switcher also supports the simultaneous working mode of all channels, that is, 4 ways can work in parallel at the same time.
4. No Interference: The USB interface only supplies power to the driver board, and does not interfere with the audio input and output circuit, and does not affect the sound quality.
5. Easy Operation: You only need to press and hold the key of the channel that needs to work at the same time for 2 seconds until the light of the channel lights up.
