The Labgear MRX600K is a I/O Port to RF Converter with Power Supply for use with Sky HD receivers (Wi-Fi models).
It allows you to connect a Sky HD box (that doesn't have a RF2 outpout) to a coaxial cable distribution set up. So you can send the output from your Sky box to other rooms in the home. You can also control the Sky box from those rooms using a magic eye, as the MRX600K will also power any eyes connected.
For sending the Sky box output to a single room through coaxial cable all you need is the MRX600K. If you wish to distribute the signal to more rooms you just need to add a DigiLink compatible distribution amplifier such as the Labgear LDU608G. A magic eye such as the SLx Link is required at each TV location (not supplied). Additional remote controls may also be required.
