1.585V
That's 1.29× as hot as professional line level, while the top of the headroom is 7.7× hotter. That is about 1.585 volts RMS.
What it means
How hot is that signal?
dBFS depends on the converter’s alignment. The +4 dBu = −20 dBFS used here is the common broadcast standard; some studios align at −18 or −14.
The math
How to convert dBV to V
The two references differ by 2.2 dB: dBu = dBV + 2.2. In volts, dBu = 20 × log₁₀(V ÷ 0.7746).
Example: 4 dBV = 1.58489 V.
