John, thanks for the reference. It gave a good historical perspective.
It would seem the use of dBv (.775 V reference) and dBV (1.0 V
reference) created enough confusion for the pro audio industry to
introduce the new unit dBu. While not an active observer in the pro
audio scene, I would
Dave,
Here's a link which explains some of the dB variations including dBu.

Dave,
dBu is dB relative to .775 volts. dBu decibels referred to the voltage
equivalent of 0 dBm into a 600 ohm load. 0 dBu = 0.775V =
2.2 dBV.
I hope this helps

Hi Dave,
Are you sure it isn't dBvu? If my memory serves me right, the VU is a
volume unit commonly used in p
Hi Dave
Here is probably more than you ever wanted to know about dBu. It is
extracted from the book "Audio Precision Audio Measurement Handbook." Audio
Precision is the world's leading manufacturer of precision audio measuring
and test equipment.
There is also a rather lengthy pag
Has anyone come across this unit before? It's referenced in EN55103-2
(Professional Audio/Video Immunity) for audio frequency common mode immunity
testing.
I realise it may be a misprint, but I thought someone else may have already
looked into it.
