Switchers have many application benefits. They can be used for signal monitoring from multiple sources, point of sale displays or for live broadcast and studio routers etc.
They vary in the number of inputs and outputs and the format standard can vary (balanced mono, balanced stereo etc). Switching can be mechanical, vertical interval or via RS-232/422.
Full Broadcast Specification Audio Switcher
Small desktop switchers occupy very little desk space and most have optional rack adapters which enable two units to be rack mounted in a 19" rack. Single 19" rack mountable switchers with full broadcast specification are also available.
