Get more hookup flexibility for your digital components with this versatile optical switch. This optical switch lets you connect up to three different optical digital components to a component with only one optical digital input. This is a round selector switch that allows you to connect up to three units with a digital optical jack and route any one of the three to a source unit with a digital optical jack. There are four optical digital jacks. One jack is connected to the unit to which you want to extend the number of optical jacks (normally a digital receiver). The other three jacks are connected to the extension units. Switch easily between these sources instead of disconnecting and reconnecting cables when you need to change inputs. Manually select which of the three units you want to use (only one can be selected at a time) with a dial on the top of the unit. The compact design will fit in tight areas between components.
