Visual and Audio Signal Paths

This diagram shows the audio and visual signal paths being used in a TV studio for a Live Show. If your recording an audio level e.g. microphones and want to mix it into the sound desk there is a mic and line level to follow, the line level is stronger and comes from any kind of sound being used for the live recording e.g. theme song, DVD. The Mic level comes from the Stob box which is connected to the microphone which is being used to pick up the speech from the talent on the panel. These levels are both analogue being put into the sound desk. The DVD however is digital and is visual aswell as audio but can convert into analogue making it easier to use and operate using a D.A.C (Digital to Analogue Converter). Sound desks can handle 12 mic inputs and 4 line inputs, the audio is then put to the mixing desk to get the right levels (not to loud or quiet) and is digitally recorded on a HDD. The visual path is more simple as the stob box, which is very important, connects what the camera is capturing and sends it to the vision mixer and the vision and audio then come together to be recorded.
