Simple VU Meter Circuit. I recently bought a cheap VU meter on Amazon, which looks very cool but needs some circuitry to get running. Unlike vintage meters, which can be driven by the audio signal directly, newer (and especially cheap) meters require DC current. A simple circuit, based on this example by Rod Elliott, uses four diodes to convert the AC audio …

The frequency response of the meter should be down no more than 0.5dB at 25Hz and 25kHz. The meter should take 300ms to reach 99% of it's travel in any direction. The meter should undershoot by no less than 1% and overshoot no more than 1.5%. The meter should read 0VU when a current of 200μA flows through the coil.

VU meter or a volume unit meter circuit is a device used for indicating the music volume output from an amplifier or a loudspeaker system. It may be also considered as a device for displaying the PMPO of the amplifier at a particular volume setting. It is also called music level indicator circuit since the music fed to the circuit is displayed through an incrementing LED bar …
