What is an analog VU meter?
What is an analog VU meter?
Analog VU (Volume Unit) Meters are for the measurement of sound or noise levels as electrical signals in audio equipment. The VU Meters have become the universal standard level for practically all audio frequency transmission systems.
Is there a simple circuit to build a logarithmic VU-meter?
A simple circuit to build a simple logarithmic VU-meter has been presented. Its simplicity really outperforms common linear VU-meters for about the same cost. Even if its accuracy is lower than what is achieved with professional equipment, it’s a good logarithmic approximation and is definitely good enough for a Hi-Fi amplifier of a stereo set.
What is VU and where is it connected?
It is usually connected at the output of the amplifier, in parallel with the speaker. The term “VU” stands for Volume Unit and should be defined with 0 VU being equal to +4 dBm, or 1.23 RMS across a 600 Ω load. 0 VU is often referred to as “0 dB” and volume units are very rarely used.
An analog VU meter with peak LED. A volume unit (VU) meter or standard volume indicator (SVI) is a device displaying a representation of the signal level in audio equipment. The original design was proposed in the 1940 IRE paper, A New Standard Volume Indicator and Reference Level, written by experts from CBS, NBC, and Bell Telephone Laboratories.
What does VU meter mean?
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 indicated on such a meter are in decibels, the zero level should not be confused with 0 dB, the threshold of hearing.
What is VU audio?
VU meter(Noun) A display in audio equipment that represents the loudness of the signal. VU meter(Noun) Any animated graphical representation of the volume of sound or music (often subdivided across channels).
