The circuit was conventionally designed with eight LED audio level meter made out of two low power quad op-amps which utilizes LM324. Volume Unit – an entity equal to a decibel for expressing the ...

The project is based on LM3915/LM3916 to produce a VU meter with the level indication using 10-segment LED bar graph. The VU meter circuit was built on a breadboard with a few components used such as ...

Juergen Grau has once again returned to Kickstarter to launch his Nixie IN-28 Dot tubes VU-Meter, under the Make 100 banner allowing those interested to help create a small production one of 100 units ...

Weston type 30, model 862 vu indicator with ‘B’ scale on RCA OP-6 portable amplifier. A Daven resistor network reduced the output from +11 dBm to telco-required +8 for 3 dB line isolation, sent the ...

It used to be a must-have on any hi-fi, a pair of moving coil meters or LED bar graphs, the VU meter. Your 1980s boombox would have had them, for example. VU, for “Volume Units”, is a measure of audio ...

VU is an abbreviation for volume unit. Thus, a VU meter is a device for measuring the level of sound intensity with audio equipment, such as amplifiers and tape recorders. Although the measurements ...

VFD displays are beloved for their eerie glow that sits somewhere just off what you’d call blue. [mircemk] used one of these displays to create an old-school VU meter that looks straight out of a ...

It is roughly the average signal level though not precisely. A VU meter is not recommended as the sole metering method for digital systems - it is too slow to catch transients which may overload the ...
