Fill level
The fill level depends on the number of activated channels in the channel list (menu item Phase 2) If the CROSS
MULTIPLEX MODE is active, it must be ensured that the maximum number of activated channels in one
modulator is not exceeded.
The data rate of the channels on the DVB-S/S2 transponders may vary depending on the image contents and on
the transmission quality. To ensure an undisturbed reception, a reserve must absolutely be observed. We
recommend you to set the maximum fill level to 95%. If the current fill level exceeds the maximal fill level, it
may cause image disturbances, such as mosaic images. The error LEDs on the front panel will light up in red in
this case.
The data rate of a DVB-C channel depends on the selected channel bandwidth (7 or 8 MHz), the set symbol
rate and the DVB-C modulation (QAM32;64;128;256) of the modulator.
If the displayed data rate exceeds 95%, there are different possibilities
to change it:
Change to a channel with a bandwidth of 8 MHz if a 7 MHz channel was selected previously.
Set DVB-C modulation to a larger value, for example, change from QAM 64 to QAM 128.
Reduce the number of selected channels in the channel list.
If the connected receivers support this option, increase the symbol rate.
