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 ...

While refurbishing an ageing audio mixer, I decided that the level meters needed special attention. Their rather horrible 100 µA edgewise movements had VU-type scales, the drive electronics being just ...

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 ...

An analog VU (volume unit) meter is a splendid moving-coil measuring instrument. It is a passive electromechanical device displaying a representation of the signal level in an audio equipment. Even ...

Given its appearance in one form or another in all but the cheapest audio gear produced in the last 70 years or so, you’d be forgiven for thinking that the ubiquitous VU meter is just one of those ...

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 ...
