Coaxial output

In this case, the term coaxial refers to a type of SP/DIF interface that uses an electrical cable with an RCA connector. This interface provides sound transmission, including multichannel, in digital format; at the same time, the electrical cable is more susceptible to interference than the optical one, but is not as fragile.

Remote IR sensor connection

Possibility to connect an external IR sensor to the device.

Such a sensor plays the role of a receiver for commands from the remote control. It is useful in cases where the set-top box is difficult or impossible to install in a place convenient for remote control — in such a place you can place a remote receiver and use the remote control without any problems. Note that the sensor itself is usually not included into the package.
