Low gain is unity, so with the knob all the way up, what voltage goes in, comes out. The knob will attenuate the signal as you turn it down.I just received my C200. Quick question - is Low gain supposed to work with headphones? I get no sound, nothing remotely audible at any volume in Low gain but working well in High gain. Switching to Low gain I can here the relays tripping but dead silence from the headphones. I have not yet tried the line outputs.

Could be that your line in signal is too low to be audible with your headphones.
As always, best to check voltages and gains yourself to make sure that everything is in order. You only need a $10-15 multimeter and some empty audio connectors
Ah yes of course, my badThe line in is the internal DAC with the signal from USB.
Try using foobar with either ASIO or Wasapi Exclusive output to play music. That will bypass any Windows settings which might mess up the volume.The volume is at max on the USB source and the C200. I think it might have a fault.
Thanks for the suggestions. I am using JRiver and am pretty sure about the output from the software. I will use a multimeter to check but I am pretty sure Low gain outputs nothing to the headphones. I was hoping someone would confirm that low gain should output to the headphone jack and that it is not a design "feature"...Ah yes of course, my bad

Also, play a 60Hz, 0dBFS test tone in foobar and measure the headphone output voltage with a multimeter. If you don't see 2.1Vrms then something is faulty. You can create the test tone very easily in REW.
You my friend are absolutely correct. Suddenly it all makes sense. THANKS!!!@Jason, I think I know what your problem is. Perhaps you are confusing, like I did, the gain with the output selection. L means line and H means headphones. To adjust gain, you have to navigate trough the function with the central big round button and the arrows. Will find an option that has a "g" in addition to the capital letters L and H. Hope this is the issue.
Can someone explain me how can I aply this function?Both of these indicate available juice to drive 90% of the headphones out there to very satisfactory levels with superbly low noise and distortion. If your headphone has a different impedance, you can compute it using the following measurement (power = V*V/R):
