Used to switch sound sources to a row of speakers on the wall. I have three devices connected: my computer, a ham radio, and another VHF radio. Since this unit's outputs/inputs are both input and output, you can switch in any direction you want, four sets of audio inputs or four sets of speakers or speakers or headphones, to infinity. The device uses mini stereo plugs on all connections. It comes with a male to male connector, so you need to buy more, just pay attention to your connector needs, such as male to male, male to female, etc. The volume works, but I warn you if you do when he does is too high, distortion will occur, so be careful. I would use your audio device to control the volume and use the switch to mute the sound.
