Why don't you show the back of the AKG HP12U 12-Channel Headphone Amplifier with USB? Can you just plug a TRS jack from a headphone jack, say on a Big Knob to the back input or do you have to use two outputs from a DAW to get a stereo signal into it?

Asked by: SamIam
There is a link on this page for an instruction manual with a drawing of the back showing the inputs and outputs.  A TRS 1/4” to 1/4” mono Y cable will provide a solution for you.

For each channel does the stereo output apply to each headphone output? Or is it Left through one output and right through the other? Basically if I plug into both headphone outputs in one channel will it be stereo in both sets of headphones?
