  • Y/C input - selectable by a jumper inside the ChromaKey's box
  • connects to the RGB port between the Amiga and the genlock or directly to a Video Toaster
  • disable switch (Genlock / Chroma) - in Genlock position the video signal is passed through unaffected
  • the Normal / Invert switch selects between blue background or subject-area dropout
  • the keyed chroma level is adjustable by the slider
  • gives Video Toaster users the choice between luma and chroma keying and is controlled completely from the Switcher
  • procedure of operating with the Toaster:
