1. IEEE 1394 input (optional) - For future interface applications.
2. Control outs - Outputs that allow you to remotely control external devices. (See "Making The Connection").
3. IR in - Accepts input from external IR receptors. Connect an IR repeater ("home run") to IR IN for controlling
the processor. This method of control is useful when the front IR receptor is blocked (for example, by a cabinet
door) or to control the processor from another room. This input is typically used in place of an emitter attached to
the front panel.
4. RS-232 input - Computer interface applications.
5. DVD Audio inputs - Connections for a DVD audio or other 5.1 source device.
Red RCA jacks
White RCA jacks
