Passive speakers require a separate power amplifier to produce sound, while powered speakers contain an internal amplifier and directly connect to a mixer. Main speakers deliver most of the sound to the audience, with the number and size chosen based on the venue size and amplifier power. Subwoofers are used with main speakers to boost low frequencies, and monitor speakers allow performers to monitor the sound.

1. Sound
What is used to amplify sound in festivals?
 PassiveSpeakers- Thesespeakers requirea separatepower amplifier in -
order to producesound.
 Powered speakers- called ‘active speakers’, they contain an internal
power amplifier. Contain a built in amplifier, they directly connect to a
mixer which reduces the amount of cables. Models such as the Yamaha
DXR series or the DBR series allow for microphones to be directly
connected and providebasic mixer functions built into the speaker.
 Main Speaker- These are the speakers thatdeliver most of the sound to
the audience or listeners. Decide on the sizeand number of speakers
according to the sizeof the venue, as well as by the amplifier output
power (in the caseof passivespeakers).

2.  Subwoofers- thesespeakers aredesigned specifically for low frequency
sound playback, and are used together with the main speakers to boost
the low-end range.
 Monitor speakers- thesespeakers areused by the performers to
monitor the sound. Monitor speakers arepositioned in various ways
depending on their shape, such as on the floor or on a stand.
