Engine Block AV (TurboBooster)

The Engine Block AV is a newer, more affordable, and better alternative to the original TurboBooster which adds new video outputs to the TurboGrafx-16 / PC Engine using a Sony CXA1645 video encoder IC. Internally the Engine Block AV uses the dbGrafx Booster TTP by dbElectronics. This product does NOT include any AV, S-Video or DIN9 cables. You will receive the adapter ONLY.

Compatible with any TurboGrafx-16, PCEngine or SuperGrafx that has the rear connector for the Booster or CD add-on. Will NOT work with CD add-on or Booster attached.

Three output connectors are found on the Engine Block AV each carrying the following signals:

  • Mini DIN9 (a.k.a. Sega Genesis 2 A/V connector)
    • RGB + CSYNC (i.e SCART)
      • Compatible with standard Sega Genesis 2 cables including 75 ohms resistors and 220uF coupling capacitors
        • We recommended a cable with CSYNC, please contact us for a recommended source. 
      • Amplified by CXA1645
    • 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 would you want mono audio anyways?)
      • 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
