Visual and audio signal flow

When mixing audio into a sound desk there is always a Line Level and a mic level, the line level is much stronger whereas mic level is recorded from a microphone. The line and mic levels come from different sources. First the Line level will come from any sound source that you want on your live footage, for example a clip of a song for the contestants to guess what it is. Then the Mic level is received from the S.T.O.B box, which is then connected to a mic to get the live audio from the participants. Both of these audio types are sent to the sound desk in analogue.The CD player can convert the analogue signal to digital using its built-in digital to analogue converter (D.A.C). Then the audio is put through the mixing desk making sure that you don’t let the sound levels go over the red bar on the VU meter, finally recorded on a HDD in digital. This means that if you duplicate the audio the quality won’t lower. And the visual side; in our studio we are able to have up to five cameras, which are sent to the stob box, out the other side and into the vision mixer. This is then overlooked by the director who tells the vision mixer which shot is supposed to be live. Finally joining the mixed audio when being recorded in to the HDD.
