Looking at the specifications of some DACs there is reference to the input or output levels using dBu. I am totally new to digital audio and used to seeing output levels in terms of voltages!

How do I compare these against my old world voltages, if say an amplifier has an input voltage of 1V, or 0.5v. In otherwords, how do I know what the output voltage of the DAc will be and therefore know that I will not have too much or too little output voltage to feed my amplifier?

Behringer:
Output Level: +16dBu @ 0 dBFS"
Input Level : -4dBu to +22dBu for 0dBFS

Tapco:
Max Input Level: +4.5dBu
Max Output Level: +4.2dBu

Edirol:
Input Level: -36 to +4 dBu
Output Level : -2dBu

E-Mu:
Input Level: 12dBV (14.2dBu)
Output Level: +6dBV

Benchmark:
Output level: -6dBu to +13.5dBu

Hope that someone can shed some light on this matter for me and educate me!!!

Thanks,
