Polytron PXU 848C 4CI 8X8 MUX Compact Heading S2 / T2 / CDVB-C

Multiplexing Compact Heading (DVB-C Off)

Polytron PXU 848C is a compact transferring that the content of 8 satellite transponders, terrestrial or cable channels converts to DVB-C (QAM). With the multiplex function you can easily generate new output channels with a capacity of different input transponders. Coded content is also no problem, thanks to the 4 built-in C1 slots you decoded content from different transponders d.m.v. A smart card, where you can optimally use the capabilities of the smart card.

Dual Modulators

Polytron Has the PXU 848 equipped with dual modulators. As a result, the capacity of the CAM modules is used more efficiently and the signals on input 1-4 can be split into 2 output channels after multiplexing and decoding the channels.
