+The settings vary between sound cards. The official V4 soundcard has these settings enabled in webconf by default:
+
+* ADC Left - Level adjustment of the left input
+* ADC Right - Level adjustment of the right input
+* ADC Left Input - Configure left input connector:
+** No Select - Disconnect input
+** VINL1[SE] - Tip & sleeve single ended/unbalanced
+** VINL2[SE] - Ring & sleeve single ended/unbalanced
+** VINL2[SE] + VINL1[SE] - Tip, ring & sleeve single ended/unbalanced
+** [VIN1P, VIN1M][DIFF] - TRS differential/balanced
+* ADC Right Input - Configure left input connector:
+** Same options as ADC Left Input
+* Digital Left - Level adjustment of left output
+* Digital Right - Level adjustment of right output
+* PGA Gain Left - Gain adjustment of left input
+* PGA Gain Right - Gain adjustment of right input
+
+Note that the gain adjustment allows coarse control of the overal gain of an input, allowing configuration for line, mic, etc. The level adjustment is an overal 0…100% level.
+
+The input connector configuration can be useful for a few variations:
+
+* Balanced signals on TSR - [VIN1P, VIN1M][DIFF]
+* Unbalanced mono on TS - VINL1[SE]
+* Two unbalanced (e.g. stereo) on TSR mixed to mono - VINL2[SE] + VINL1[SE]
