For me, the desire to buy a Linux receiver showed with 4 Tuner, even though I had only one cable as supply. I have therefore the EXR 551 switched 504 incl. Power supply from the existing EXR and could lead 4 separate channels via a line. So I can now view completely independent with 4 tuners, record or stream over the network.
The output power is at all frequencies so high that over the previous EXR 504 supply no signal degradation has occurred. These words, the cable length is 15m 10 year old Satkabel. Through the massive cast housing the topic Potential equalization unnecessary largely because all sockets on the housing, and this is connected via the connection at the antenna unit with earth.
In sum a convenient and compatible upgrade for existing installations.
