Default levels are denoted as follows:
–31.4
NoTe!
The input clipping levels and
the absolute max output levels all
assume sinusoidal signals for the dBu
values.
Tip!
To convert dBu values to dBV,
subtract 2.2 dB from the dBu value.
example:
–10 dBu => –12.2 dBV
Audio inputs 3 & 4
NoTe!
Audio inputs 3 & 4 are referred
to as Line input 1 & 2 in the API.
