Everyone that owned a TG-16 also had a TurboBooster, right? I doubt that. If you wanted to use anything other than RF out, you needed the TurboBooster. It would get you composite output and stereo audio. They have since been hard to find in good working order or at all. There is a way to make a cable to plug into the expansion port on the back to get composite output but its just feels janky and a non-permanent solution. In comes the AV Block which I picked up from StoneAgeGamer earlier this year. This unit plugs into the TG-16 expansion port and gives you many output options due to its use of the Sony CXA1645 video encoder chip.

Three output connectors are found on the Engine Block AV each carrying the following signals: (Specs was taken from StoneAgeGamer)

  • Mini DIN9 (a.k.a. Sega Genesis 2 A/V connector)
    • RGB + CSYNC (i.e SCART)
    • Video level CSYNC
    • CVBS (a.k.a. composite video)
      • Compatible with out of the box yellow/white/red Sega Genesis 2 A/V cable
      • Transcoded from RGB by CXA1645
    • Stereo Audio Only
      • While the Sega Genesis 2 A/V pinout permits mono audio, it is not supported by the dbGrafx Booster (why the hell would you want mono audio?)
      • Amplified on dbGrafx Booster
  • S-Video connector (a.k.a. Mini DIN4)
    • Y/C Video
      • Compatible with standard S-Video cable
      • Transcoded by CXA1645
  • RCA Jacks (yellow/white/red)
    • CVBS (a.k.a. composite video)
      • Direct signal from console (i.e. same as original Turbo Booster)
    • Stereo Audio
      • Amplified on dbGrafx Booster
