At some point while you are enjoying our home theater system, you will probably want to make an adjustment
but would rather not have to get up and walk over to the system. What is desired is some type of a remote opera-
tion. Thankfully there are many ways of operating a system from a remote location, the most common being
infrared (IR).
Infrared technology allows you to send commands, by light beam, to your equipment and have them respond as
though you were actually touching the unit. The basic design of this type of control, the equipment required, and
connection to the A6600, is what will be described here. This information is specific to this example and the user
should refer to all the component manufactures literature supplied with their particular system.
Infrared systems are composed of two main units, a sender and a receiver. The sender interprets your request,
converts it to an infrared signal and transmits it through a medium over to the receiver. The receiver receives the
signal and presents it to ("flashes") the equipment to be controlled. The equipment then interprets the signal and
performs the requested operation.
Sender
The sending process begins with the user. The sending unit, normally a handheld remote, is raised and pointed at
an IR receiver and a button activated. Inside the remote, the command from the user is converted to a code spe-
cific to the sending unit; modulated at some frequency to ensure better reception, and then transmitted via infra-
red light over to the receiver. The IR receiver detects the code and sends it through the cabling to the A6600. The
A6600 then either processes the command directly or hands it over to the external device via an IR emitter. The
IR emitter is a secondary sending device that reconverts the code back into IR energy and flashes it at the devices
IR window to exert control.
Receiver
The IR receiver is usually recognized as a small window located on the front of the equipment. A variation of this
concept is the receiver placed inside of a wall-mounted keypad or mounted separately in a gang box or tube in a
remote location. The receiver detects the IR energy and converts it to an electrical signal that can travel through
wire. As the cable is run from the remote location to the unit to be controlled, the user is now able to operate his
or her remote from a location other than the front of the actual equipment. The equipment that receives the cable
may also "pass-thru" the code by using an IR emitter to flash other equipment. The equipment picks up the signal
and interprets it the same as if the remote were actually in front of the unit. *See Diagram
The above illustration demonstrates the remote (a), sending the IR signal over to the keypad (b), the keypad
passing the IR signal down through walls via cable (c), and over to the A6600 (d). An IR emitter (e), connecting
to the A6600, then re-broadcasting the IR signal to the unit (f) to be controlled.
