Pt-VGA0802/04/08-A VGA switcher is a matrix switching device that supports 8-channel audio and video signal input as well as 2, 4 or 8-channel audio and video signal output. It is used to synchronously or asynchronously switch multiple computer signals as well as audio and video signals to one of the multiple output channels.

Features
1. Our VGA switcher adopts the distortion compensation technology for long-distance signal transmission.
2. Programmable logic array circuits are adopted and arbitrary switching is supported.
3. Audio and video signals can be switched synchronously or separately.
4. Channel switching permission settings are supported and the switching permission of audio and video channels can be managed separately.
5. Five-pin 3.8mm Phoenix connectors are used for audio signal input and output.
6. The volume of each audio output channel can be separately adjusted.
7. Our VGA switcher supports power off memory function and power failure on-site protection function.
8. Housed in a 2U metal case, this VGA switcher can be installed in a 19-inch rack.
