This point ends up about two-thirds of the way across the scale. Typical VU meter. Source: Hoyt Meter The scale to the left of the zero point is generally in black, with a value of -20 dB all the ...

Most VU meters have a scale from -20 to +3, and rise and fall times of 300 milliseconds (ms). If a constant sine-wave of 0 VU is applied, the meter will achieve 0 VU in 300 ms. Readings on the VU ...

A VU meter registers zero level on its scale when the voltage = 0.775 at 1 milliwatt & 600 ohms impedance. This is usually modified so that 0 (zero) corresponds to 1.23 volts or + 4 dbm. The ballistic ...

A reference power level shown on a VU METER. Although 0 VU is shown on a VU meter as the point of 100% MODULATION, it is not identical to the reference called zero level, which in fact refers to -4 dB ...
