Led VU Meter: 7 Steps (with Pictures) instructables In this instructable, I will show you how to put together an analog VU meter. You can plug any light in (with the right voltage ofc) and it will work. A Vu Meter is simply measuring the volume of the sound, the bigger the voltages, the higher the light will go on the bar. How to build VU Meter 2 circuit diagram How to build VU Meter 2 August 8, 2010 category: Sound level meter. Description. A circuit of measurement of level based on a typical application of National. The circuit round the IC1 makes input adaptation and amplification with the trimmer TR1 [GAIN]. The circuit round the IC2 makes half wave rectification of acoustic signal. Simple & Easy to Make Vu Meter or Audio Meter Using LM3915 ... Setting the Vu Meter: To set the Vu meter, power the circuit with 12V for optimal performance without an input audio signal. Now using the 10k pot adjust such that only the D1 & D10 glows. Once this has been set, connect the Pin 9 to the Vin, if the adjustment is right all the LED'd should glow if not the repeat the adjustment procedure. Building an LED VU Meter: Wiring | DoItYourself Building an LED VU Meter: Wiring. VU means Volume Unit. LED means Light emitting Diodes.

So thought it would be easier to put together a quick video showing a step by step build. With download ... HOW TO SET RECORDING LEVELS Welcome :: News Most open reel decks use the VU type meter. Recording levels are set so that the meter barely goes into the red, indicating that the average signal is at 0VU with peaks at 6 to 8 dB above. Peaks can occur so quickly that sometimes VU type meters will appear completely motionless even when the sound is easily audible. How to build VU Meter 1 circuit diagram It can be adapted in various levels of entry, regulated from trimmer TR1 (Level) TR2 (Gain), then it is rectified by the D1 2 (cutting off of negative periods of signal rectification) and drived to the main circuit of index, that it is constituted by D3...D13 , the transistors Q2 Q13 and the materials that exist around them.
