Public Address systems are made up of
five elements : see video for ensemble.
(Vid 2, Anonymous 2013)
Source (what is producing the sound)
Eg. Microphone
Monitor
Monitors enable musicians to hear the balance of sources and
each can be adjusted to musician's preference.
Mixer & Amp
The mixer is used to balance vocals and instruments and send
this information to the monitors. An amp amplifies the audio signals from speakers and is
normally connected to the mixer .
An XLR cable is commonly used to connect equipment because it helps ‘deliver balanced microphone and line-level signals over long distances’ (Mack 2014).
'Audio cables are particularly susceptible to electrical interference' (Palmer, 2000 p198). To avoid reduction of sound quality keep electric and audio wires as far apart as possible.
