Audio and Video signal path

An Audio Mixer has 12 Mic inputs, and 4 Line inputs. A Mic level has a weak signal, whereas a Line level has a strong signal (1 volt). All equipment in the 21st Century is digital. There is a few differences between analogue and digital signals. An analogue signal is tolerate, and can take frequency's louder than it is designed to have (can handle +3, +6, +9). Whereas a digital signal cannot handle this without becoming extremely distorted and ruining the sound quality. This is measured in a VU meter, which measures frequency / volume units of audio. You must not allow the signal to go above 0, as the signal will become distorted, and the meter will turn red to warn you that the signal is peaking.

A line level is always shown when mixing audio into a sound desk. It will be the more stronger signal and there will aslo be a mic level which shows any audio recorded from a microphone. The mic levels come from different sources. The line level will come from the soundtrack in your live footage and the mic level is received through a stob box which is linked to a microphone which captures audio from the talent and host. Both audio clips are put through a sound desk in analogue. The CD is digital but contains a Digital to analogue converter (D.A.C) this makes the sound easier to work with. As the audio is put through the mixing desk, making sure it is at the right levels so ntohing distorts it is then recorded on a HDD in digital which makes the audio recording solid meaning if it is copied the quality will not change. A sound desk is able to have 4 line inpurts and 12 mic inputs giving a chance to record the most complex live videos. The visual side of mixing is easier as on the studio side of the wall we are able to have five different cameras which are then put through the stob box in the wall out the other side and into the vision mixer. This is controlled by the director making sure he is receiving the best visuals needed for the show. Finaly, the visual meets the mixed audia when being recorded in to the HDD (DN300).
