Peculiarities ofthe ampli er5396. How can you control aLNB?

Respuesta: 

The reference 5396 is an ampli er with 4 inputs and one output + test, split-band ampli cation with all the bene ts that entails, avoiding interference between VHF and UHF, and allowing a higher output level.
The peculiarity of this ampli er is that allows receiving terrestrial and satellite signals, and control the polarities of LNB from the domestic receiver.
The amplier can power preamps to 12 Vdc from all its inputs.
This powering can be canceled by

 

a switch located at its rear.
But, How can manage the LNB this amplifier?
1. From your domestic receiver, you can select the desired polarity by enabling the tensions12 or 17 Vdc.For this purpose, position theswitchSW1in REMOTE.
2. Only a  xed polarity can be selected. For this, theSW1 is positioned inLOCAL, resulting inconstant12 Vdc that are sent to theLNB,and thus sets theverticalpolarityfor thatvoltage
