Spaun SBK 5503 NFI 842488 User Manual

•  The power launch amplifier features 12 SAT IF trunkline

  inputs and outputs in total for reception and distribution  

 

  of 4 SAT IF signals of each SAT system A, B and C
•  To ensure logical allocation of the IF signals according

  to the DiSEqC circuit criteria, the IF signals must be  

 

  connected to the power launch amplifier according to  

 

  the marking on the unit
•  All IF amplifiers feature an integrated 6 dB slope.
  Each SAT system features a synchronous level controller. 
 Thus an adjustment of different signals up to 10 dB is

 possible.

•  The terrestrial input is return path
 

compatible. Supply voltage selectable in both

 

directions: 0 V / 18 V (500 mA)

•  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
