Decibel (unloaded) (dBu) | RecordingBlogs
https://www.recordingblogs.com/wiki/decibel-unloaded-dbu
An unloaded decibel (dBu) is a unit of measurement of the ratio of an amount of voltage V to V 0 = 0.7746 volts given by the formula 20 log 10 (V/ V 0) = 20 log 10 (V/ 0.7746), where voltage is measured using quadratic mean (also called root mean square, RMS). For example, the professional audio and studio recording level of +4 dBu means

“Rupert Neve gives a dialog of the origin of “dBu”.nnhttps://www.youtube.com/watch?v=b02P4f3CBuMnnHe states the difference is the dBm is measured into 600 ohms, whereas dBu is measured into 150 ohms. nnOr something like that ;)nnAnyhow – See

The home recording level (consumer audio) of −10 dBV means 0.3162 volts, that is −7.78 dBu. The studio recording level (pro audio) of +4 dBu means a voltage of 1.228 volts. The maximum undistorted level of audio amplifiers is +18 dBu. In USA it is +24 dBu.

dBu dBu scale is used to measure input and output levels (on a decibel scale) for Professional Audio equipment (Example: your studio mixer, Amplifier). It is a logarithmic ratio of two voltages (V to V0) with a reference voltage of V0 = 0.7746 volts. So 0 dBu = 0.7746 volts. The formula to calculate dBu is, dBu = 20 log (V1 / V0) where V0 = 0.7746 volts.

dBu measures decibels relative to 0.775 volts with an open or unloaded circuit. (The “u” in “dBu” stands for unloaded.) While 0.775 volts may seem rather arbitrary, it is the voltage level that delivers 1 mW in a 600Ω resistor, which is the standard reference impedance in a …

Using the above chart, you can easily understand that 0dBFS (maximum digital audio signal level) is equal to +24dBU in analog. +3VU is roughly equal to -17dBFS and +7dBU. Applications and Uses of dBFS, dBU in Music Production. 1.) No analog signal or voltages should be described in terms of dBFS.

Pascal is the international unit of measurement for sound pressure. dBu: 0dBu = 0,775V, or 0,775 Volts. In the form of +4 dBU (1,23V), it represents the line level on professional equipment. dBv: 0dBv = 1V. In the form of -10 dBV (0,316V), represents line level in semi-professional equipment.

dBu – This is the norm in professional audio hardware. It’s a scale where 0 dB is equal to 0 . 775 Volts RMS in an unloaded or unterminated circuit. (Hence the “u”.) +4 dBu is the voltage reference level used by professional audio product, meaning that when your analog VU meters show “0”, you’ve got 4dB above .775 volts going through your 0 ohm circuit.

+4 dBu is another measurement of standard operating signal level. In this case, it often describes pro audio gear. Yes, +4 dBu is innately louder than -10 dBV. But it’s not 14 decibels louder, and that’s because 0 dBu stands for “0.775 volts of alternating current into an unterminated load.”
