To adjust input gain on the Digi 001 (Analog inputs 3–8):
1
Connect the instrument or device to the Digi 001 I/O Box.
2
In Pro Tools LE, choose Setups > Hardware.
3
Click Other Options.
4
Set the input trim slider to match the output level of the connected instrument. Refer to
the manufacturer’s documentation for details. If you do not know the output level of the
device, use the default input trim level, then fine tune the input level gain using the
procedure below.
5
Click Done.
✽ Increasing gain raises the noise floor. Make sure that the device you have con-
nected is outputting as strong a signal as possible without distor tion, then set
the input gain accordingly.
To fine tune the input level gain (Analog inputs 3–8):
1
Create an Auxiliary Input track by choosing File > New Track. This can be either mono
or stereo depending on the device you are monitoring. Option-click (Macintosh) or Alt-
Click (Windows) the fader on the track to set it to unity gain (0 dB).
2
Set the track input to the correct Digi 001 input channels or channels.
3
Play the instrument at the volume you will record.
4
Note where the instrument output signal registers on the on-screen meters in
Pro Tools LE. Good levels are in the yellow range of the Pro Tools LE track meters. If the
levels hit the red, they are clipping, and you should lower the input gain.
5
If the meters are not clipping, and they are not in the yellow range, open the Other
Options dialog and increase the input gain by raising the volume slider for the
appropriate input. Click Done and play the audio source again. Repeat until you have a
strong signal without clipping.
