12 led vu meter circuit


Posted on Feb 6, 2014

This is a simple visual indication of the audio level signals, adaptive to various user needs. Can be adapted to different input levels, adjustable by trimmer TR1 (state) - TR2 (Gain), then rectified by diodes D1-D2 (standard negative mark-recovery periods) and driven in the main circuit indication, consisting of

the diodes D3 up to D13, transistors Q2-Q13 and materials that exist around them. The visual indicator is taken from the series of diodes LED LD1-13. Each Led illuminates when the level changed during about 0, 65 V. The power requirements are 100 ma full term. We can add as many steps we want LED, always assuming the power where you need the new LED.
