Key features
  • amplification of terrestrial and satellite signals in multiswitch systems supporting dSCR/Unicable standard
  • DiSEqC support
  • built-in DC power supply for remote powering of system components,
  • connectors marked "22 kHz" and "DC out2" can be used for connecting PC102W R80561 programmer for remote control of multiswitches
  • gain adjustment in the Terr. and SAT paths
  • stepless Slope adjustment (frequency characteristics correction)
  • die-cast housing
MSA R80515 is designed to amplify radio and over-the-air TV terrestrial signals in the 47-862 MHz band and SAT IF signals (in the 950-2400 MHz band) in SMATV systems. The model is also recommended for use in multiswitch installations (dSCR/Unicable), where large distances and passive satellite splitters cause signal power to drop below the tuner's sensitivity threshold.
MSA R80515 is fitted with switches for gain and slope adjustment. The built-in cable attenuation compensation equalizes the frequency characteristics at higher frequencies. The amplifier has input, output, test and auxiliary connectors.
The die-cast housing provides high screening efficiency by preventing the penetration of interfering signals to the unit.
