    2. General information The new models PXU 848 C and PXU 848 T of the compact headend series enable the combined processing of encrypted and open channels. This allows an easy and cost-effective extension with centrally decoded services for the community antenna system. Also possible is the use as a free-to-air basic supply in a small boarding house or hotel, because 40 programmes of 8 transponders are available.

  • Page 6: Input Circuit

    5. Input circuit In the PXU 848 C/T, signals are directly fed to the input tuners. Due to the triple tuners, there are eight inputs each for SAT and eight for terrestrial signals (DVB-T/T2 or DVB-C). In the ‘factory settings’ condition, there is a 12 VDC voltage for LNB supply on SAT input tuners 1, 2, 5 and 6.
