This device accepts two A/V inputs and will give priority to input 2 whenever a video sync pulse is detected on that input. When video sync is removed, unit will automatically switch back to input 1. A delay knob allows you to adjust the time before the unit switches back to the non-priority input. Can be easily modified to operate in manual mode by removing a jumper on the circuit board. When in manual mode, the device can be controlled via IR, 12V trigger or push-button control. Has a built-in IR teaching LED to program your learning remote control. Ships with power transformer, connectors and instructions.
