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.

摘要： Certain embodiments of the invention may be found in an ultra low power dosimeter assembly. The ultra low power dosimeter assembly may comprise a low power voltage source and a table circuit. The table circuit may be adapted to convert an input voltage to a second voltage level. The second voltage level may correspond to noise dose. The ultra low power dosimeter assembly may also comprise a switch adapted to trigger a control circuit. The control circuit may provide progressive attenuation of an output signal as the second voltage level increases. In certain embodiments, the control circuit may also be adapted to send one or more warning signals to a user of the ultra low power dosimeter. The one or more warning signals may be sent when the control circuit determines the second voltage level has reached one or more pre-determined threshold voltage levels.
