Abstract: Audio level indicators are known which comprise moving needles, or an array of lights, or an illuminated bar. However, the way in which they provide information is fixed. A programmable audio level indicator for use with a mixing desk is provided which comprises a first light source arranged to emit a coloured light, in response to an audio signal received from a connected audio source, to indicate the audio level of that received signal, the indicator arranged to vary the colour and intensity of the light emitted as the audio level changes, wherein the indicator is configured such that the audio levels at which the colour changes are selectable, the indicator further configured such that the colour emitted to indicate an audio level, or range of audio levels, is also selectable.
