The three input jacks connect to the source devices and allow you to output digital audio to your main unit. Switch easily between sources instead of disconnecting and reconnecting cables when needing to change inputs. The compact design will fit in tight areas between components. Works with the following digital audio components - Home/portable digital audio components with optical connection, MP3/CD/DVD player including Blu-ray/HD DVD, video game consoles (PS3/XBOX360), computer sound card, cable/satellite receiver to your home theater system with a digital optical input. Operation - To hear your connected sources through your home theater system, turn on your home theater system and the audio source you want to hear. Then, press in the lock release button on the selector's dial and rotate the dial to the indicator corresponding with the source you want (1,2, or 3). A green indicator shows which of the three units is selected (only one can be selected at a time). Release the button to lock the selector in place. The sound from the selected source comes through your home entertainment system's speakers.
