Obviously, the unit can be embedded into an existing mixer, preamp or power amplifier, and powered by the internal supply rails in the 9 – 30V range. Unfortunately, an oscilloscope and a sine wave frequency generator are required to accurately setup this circuit. A careful setting of Trimmer R5 will allow triggering of the LED with a wide range of peak-to-peak input voltages, in order to suit different requirements. This will help the operator in preventing severe, audible distortion to be generated through the audio equipment chain.This unit is particularly useful in signaling overload of the input stages in mixers, PA or musical instruments amplification chains, but is also suited to power amplifiers. is reaching the onset of its maximum permitted peak-to-peak voltage value before an overload is occurring. and can be used as a separate, portable unit, to signal by means of a LED when the output wave form of a particular audio stage is “clipping” i.e. This Audio Clipping Indicator circuit was intended to detect clipping in preamp stages, mixers, amplifiers etc. Published:6 21:18:00 Author:muriel | Keyword: Audio Clipping, Indicator
