3.0 Audio input and output
The AI-Delta supports two types of audio I/O:
2 USB ports
l
2 DB-15 connectors

Input impedance
Input level
Input gain
Note: The AI-Delta gain covers a total range of 65 dB. You can set the range of +10 dB to
+65 dB in 1 dB steps; however, you cannot select the range 1 dB to +9 dB as a function of
design.
