1. The 6-channel input adopts high-contact reliability self-locking key switches for switching. When one key is pressed, the other switch automatically up to disconnect the circuit. 2. Two groups of outputs can be output simultaneously and can be connected to power amplifiers or active speakers to produce sound at the same time. Adopt the L/R simultaneous switching mode. All inputs and outputs of GND are universal. 3. Simple installation: The input and output are plug-and-play, making installation convenient. The signal source can be switched without loss, allowing you to enjoy a different listening experience It is mainly used to select and switch stereo signal inputs and share the output of one or more sets of devices, such as multiple stereo signal sources (TV audio, MP3) Devices such as players, CD players, video games, mobile phones, tablets, computers, and record players need to output to power amplifiers or active speakers. 6 groups of audio signal selection switchers solve the complex line plugging and unplugging operations. Just connect the signal sources of the devices that need to be input to the switcher uniformly Product Parameters: Color: Black Interface: interface Power supply: No external power supply required, plug and play Adopt the L/R simultaneous switching mode. All inputs and outputs of GND are universal. Input/Output interface: Standard interface Number of input channels: 6 stereo selectable switching inputs Output channel number: 2 stereo synchronous output channels Material: Metal Package Contents: 1 x Audio Signal Selector Switcher Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
