8.44. FADERI -- Set Input Gain Fader
The input channels of the Vortex pass through an analog gain stage before reaching the analog to digital
converter. The gain of this stage is adjustable via a the
GAINI command. Once in the digital domain, there is an
additional gain stage, referred to as a fader. The fader gain is adjustable by the FADERI command. The
GAINI
setting should be used for calilbration in order to maximize the resolution and quality of the signal at the analog
to digital converter. The FADERI command is provided as a way to do volume control on the inputs without
affecting the calibration.
This command was introduced in firmware version 2.5.0.
