Reference level simply means that a recognized signal will be produced at a certain volume level at the seating position / microphone position. That's it.

A technician calibrates an audio device by using an AC voltmeter. Here, 0dBu is referenced to .775volts RMS. While this voltage may seem an odd choice, when applied to a 600W load (read: "vintage" gear) the power dissipated is 1 milliWatt, a nice, clean point-of-reference. An additional .455volts yields 1.23 volts or 4 dB.

Professional audio equipment adheres to the professional line-level standard that is technically +4dBu (Sorry!), commonly referred to as just +4. Back in the days when we used tape machines and consoles, we aligned all the machines so that an input or output level of +4dBu translated to 0 on the VU meters. What This Means to You
