It is a power measurement where 0 dB references a 1 mW across a 600 ohm load. This is great for old telephone lines and old-timey motion picture equipment, not so great for modern pro audio circuits. 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.
