The chain commences with microphones, or D.I. Boxes to pick up the sound to be sent to the mixer.

Microphones often require stands.

Microphones & D.I. boxes always require cables, usually XLR type, to connect to the mixer.

The mixer is used to control the levels of each input and outputs different balances of mix, such as monitor, sidefill or front of stage to the appropriate amplifiers.

In higher level systems, an “active” crossover is inserted (Via XLR cables) between the mixer and the amplifiers, (Again XLRs) dividing different frequencies of sound before amplification.

The Amplifier connects to the speaker via a Speakon lead.

Amplifiers increase the level of signal to drive the speakers into creating an audio signal. Larger speakers are better at reproducing lower frequencies, whilst smaller ones are more effective at high frequencies.

Various types of speaker are used in differing systems, common types are full range, but higher levels split between sub bass, bass, mid and high frequency. The lower the range the speaker is producing, the more power it requires.

Amplifier power is measured in watts, but this is not (as commonly believed) the defining factor of how loud the system will be. Speaker efficiency also has to be taken into account.

Below, is a brief summary of the use of components available for hire.
