Audio signal types - loudspeaker and headphone level

Level of challenge Easy


Welcome to this tutorial on loudspeaker and headphone level signals.


The signals sent to loudspeakers and headphones must move their transducers so that mechanical energy can be converted into the changes in air pressure which we perceive as sound. In order to move a loudspeaker driver transducer, the signal must be much more powerful than it is when it is being recorded, processed and mixed.

Speaker level signals are suitable for driving loudspeakers and care should be taken not to send them to any other type of device. They are produced by power amplifiers whose sole job is to amplify a line level signal to a level capable of moving a driver.


Headphones aside, speaker signals are the last in the audio signal chain before sound reaches our ears.

Headphone level signals are similar to line level and can often be treated as such. With care, it is perfectly possible to connect the headphone output of your mobile phone to a line level device.
