Speakers

What is the difference between Active and Passive speakers?

·         Active speakers have an inbuilt amplifier.

·         Passive speakers do not have built-in amplifiers and need to be connected to one via a speakon cable.

-          Explain how speakers may differ when used for the main PA for the audience as opposed to monitor speakers.

·         Main speakers send out the majority of the sound that the audience hears. They are often larger than monitor speakers, and there are often more of them as well. They can come as floor-standing or put on stands.

·         Monitor speakers direct the sound back towards the performer(s). They often lie on the floor, but can also be placed on a stand. They give an unbiased sound so that the performer(s) can hear a true response.

-          Explain what a full range speaker system is.

·         A full-range speaker is a type of loudspeaker whose range is enlarged with the use of a whizzer cone. They can cover almost all frequencies audible by the human ear. Smaller systems often have a smaller range.

-          What unit do we measure the power of a speaker in? What unit do we use to measure its loudness?

·         The power of a speaker is measured in watts (W).

·         The loudness of a speaker is measured in decibels (dB).
