If I recall correctly, 0 VU equals 1 milliwatt sinusoidal RMS
into 600 Ohms (probably 1 kc is the standard tone).  So if you have
a 600 Ohm output with a 600 Ohm load, 0 VU is somewhere around .77 V RMS,
which is about 1V peak or 2V peak-to-peak.  So if you know what code
on your DAC would produce that voltage, then you'd have a standard 0 VU.
But that may not be as important as just providing a dancing bar graph
with an arbitrary 0 VU.
