Configuring 96i I/O Controls
To configure controls for a 96i I/O:
1 With the 96i I/O selected in the Peripherals list, configure your I/O front panel meters for input or output metering from the Meters pop-up.
2 Set input sensitivity by doing the following:
*   
For Inputs 1–4, set the input trim slider to match the output level of the connected instrument. Choices range from –12 dBV to +4 dBu. If you do not know the output level of the device, use the default input trim level, then fine tune the input level sensitivity.
*   
For each input 5–16 being used, select –8 dBV or +4 dBu as appropriate to best match the output level of the connected instrument.
3 Set Output levels (select –10 dBV or +4 dBu).
4 Click Done.
 
You can select analog or digital input as sources for 96i I/O channels 1–2. Only channels 1–2 can access the S/PDIF inputs.
To select analog or digital input for channels 1-2:
1 Choose Setup > Hardware, and select 96i I/O in the Peripherals list to display the 96i I/O window.
2 Click to set Ch 1–2 Input to Analog or S/PDIF, as appropriate.
*
The 96i I/O only supports analog and digital switching for channels 1–2, and only from within the Hardware Setup and I/O Setup. The 96i I/O does not support path remapping within I/O Setup.
