USB and Ethernet
A USB port is provided on many home theater
receivers. This allows you to play music
stored on flash drives or other compatible
USB devices and, in some cases, power
a smartphone or another compatible USB
device.
A growing number of home theater receivers
also provide network and internet connectivity.
This can be provided by connecting an
Ethernet cable to the receiver using a provided
Ethernet/LAN port.
However, a growing number of home theater
receivers provide both Ethernet and Wi-Fi
connectivity, which provides added flexibility
as to where you place the receiver in relation
to a broadband router.
RS232, IR Sensor Cable, and 12V Trigger

On high-end home theater receivers, you may
find this trio of connections:
RS232
Provides a physical connection to a PC or
custom home theater controller.
IR Sensor Cable Input
If this is an input, you can connect an IR
blaster cable so that the home theater receiver
doesn’t have to be in a direct line of sight for
your remote control.
If this is an output, it allows the home theater
receiver to blast an IR signal to control another
receiver.

12V Trigger
This connector allows the receiver to turn other compatible devices on or off or to start some functions, such as
lowering or raising a video projection screen.
