Default What's a dBu ?

Forget microVolt!
0 dBu is steady AF established at 775 milliVolts line level -- regardless
of load Z.


It is an easy mistake to make, because dB relative to a microvolt is often
written as dBu rather than
using the Greek letter 'mu'; a limitation of the ASCII character set!!

dB relative to a microvolt is written as dBuV, so there need be no
confusion.
