Global Invacom FibreIRS® dSCR GTU

Not yet reviewed
Product Code: D000199
Information

The dSCR GTU converts optical power to RF power (4 satellite bands and FM,DAB,DTT ). Terrestrial signals are overlaid onto both output ports. All units have built in AGC which allows a wide dynamic range of optical levels without affecting output power and quality. One LED indicator allows the user to monitor the status of the unit. Able to work in legacy, analogue SCR (aSCR) and digital SCR (dSCR) modes.

Features

  • Optical to RF convertor (Satellite and FM,DAB,DTT )
  • Compatible with SKY Q, EN50494, EN50607, SKY SCR SKY Classic/Legacy
  • Automatic Gain Control (AGC)
  • LED Status indication for diagnostics
  • Discrete stylised design for home installs
