I have the DAC+ADC working and currently using the jumper to change the input gain between 0db and 32db. I was wondering if finer control over the input gain can be achieved? Or do I need the DAC+ADC Pro for this?
If finer control is not possible, can I connect a switch to the gain pins instead of a jumper? In other words, is one side of the J1 pins connected to the same source? As in, I can keep either right or left side on the same pin and just change the other row?
