Raise the gain on the appropriate Input of the Vortex device to +10 dB.

Lower the gain on the appropriate Output of the Vortex device to -10 dB.
It is important to set the gain structure correctly so that you don't clip the input audio
stage of the codec and that the Vortex device gets a good signal to perform processing
with. The nominal input and output of the codec is .3 V rms. The nominal input and
output of the Vortex device is .775 V rms. This equates to a difference of 8.24 dB between
the two nominal levels. For simplicity, you may round that value to 10 dB.
