Spaun SBK 5503 NFI 842488 User Manual

•  Synchronous level adjuster for each SAT IF system
•  LNB supply voltage selectable for the use of  

Quattro (12V) or QUAD LNBs (22 kHz)

•  The terrestrial input is passive and return path
 

compatible with the possibility of a 18 V (250 mA) remote   

 

current in both directions for an amplifier. 

 

•  Selective standby function:
 

If all subscribers only watch TV programms of SAT system A  

only the appropriate LNB is supplied with power. The

internal logic turns off the power supply of all other LNBs as

 

well as that of the integrated amplifiers.

 

This process results in significant energy savings!
