Inputs/multituner

Headend devices with multituner can receive DVB-S/S2/S2x, DVB-T/T2 or DVB-C. For receiving DVB-T/T2 or
DVB-C the LNB power has to be switched off before connecting a antenna cabel to one of the HF
inputs (see 3.3.2 on page 17)!
Direct connection to the LNBs
The devices have a remote supply voltage for the LNB and DiSEqC 1.0 functionalities at the inputs. The inputs
can be connected directly to the LNB.
Multiswitches as input distributors (recommended)
Optionally, you can also use multiswitches as input distributors. The advantage of this solution is that you can
set both the polarization and the satellite via the user interface. Changes in the list of programmes can be
made using remote maintenance, so that it is not necessary to change or modify the input distribution on site.
Demodulation of the data stream
The selection of the frequency and the demodulation of the data stream are both done in the tuner.
If needed, the programmes from the data flow of the demodulated transponder can be filtered (Remux mode).
Thanks to the Cross Multiplex Mode, FTA programmes (Free to Air) can be filtered from the data flow of
several tuners for a common output channel and be bundled again.
The prepared data flow is passed on to the modulators.
