Global Invacom - Optical TV - Optical to dSCR Converter (sky Q), Global D000199

Item Code: D000199

Brand: Global Invacom

Manufacturer: Global Invacom


The dSCR GTU converts optical power to RF power (4 satellite bands and FM,DAB,DTT ). The terrestrial signals are overlaid onto both output ports.

The dSCR GTU unit has 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.

The dSCR GTU unit D000199 will work in legacy, analogue SCR (aSCR) and digital SCR (dSCR) modes.


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