PA (Public Announcement) Systems
PA Systems are basically amplifiers, each one has:
- VGA Leads
- In-line mixers
- CD Players
- Auxiliary Leads
Mixing desk control anything that is onstage with a microphone, including, for example, individual speakers – equalization is useful when someone with a quiet voice is carrying out a speech. Sound can be manipulated from mixing desks; instruments can be removed.
Technical specifications help performers on stage feel more comfortable. It allows technical workers to set up the position of the band members (their instruments) before their arrival, allowing them to immediately perform on arrival.
Here is an example Tech Spec, found on Learning Space for Falmouth University:
