8.58. GAINI -- Set Input Gain

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 digitally controlled analog trim pot. It is important that this gain is set correctly in order to maximize the resolution and quality of the signal at the analog to digital converter. This command lets you adjust the gain of these input gain stages. For volume control, the FADERI command can be used to adjust the signal level in the digital domain

without affecting the calibration.

This command also adjusts the gain of the input signal coming from the telephone interface.

The following table shows the relationship between the input gain settings (via GAINI and MIC) and the nominal level expected at each of the inputs.

Input Channel	MIC Setting	GAINI Setting (dB)	Expected level at Input (dBu)
1	1 (mic level)	0 to 30	0 to -30
1	0 (line level)	0 to 30	33 to 3
A-B	N/A (line level)	0 to 20	0 to -20

The GAINIT command has a range of -100 to +20.

This command is a channel integer command. See Section 6.3 and Section 6.2 for more information

on this type of command. The minimum and maximum values for this command are 0 and 20 or 30, respectively.

This command is saved to non-volatile memory only as part of a preset. The state of this command will be restored after power-up only if a preset is saved and that preset is set to be the power-on preset.
