Not to resurrect this thread from the grave as I'm sure you've found the answer elsewhere. There is no true level conversion standard between the analog and digital world. There are several guidelines that people have adopted.. -18dBFS, -12dBFS, etc. But the only way to truly know that your converters are putting out +4dBu (1.23 RMS volts) is to use a meter. My rig at work, for example, requires -12dBFS.
