Components

of Signal Flow for Television...

  • Cable (audio, video, or both) - transmits the signal
  • Video source (camera) - captures the signal
  • Audio source (mic or device) - captures the signal
  • Video switcher (tricaster or ATEM) - mixes the video and audio (post-mixer)
  • Audio mixer - mixes down the audio
  • DA - Distribution Amplifier - distributes and amplifies a signal
  • Monitors (audio or video) - shows the signal

AC/DC

Alternating Current

Direct Current

Can be transmitted

over long distances

Needed to power household appliances etc.
