Question about my Pimeta v.1 Headphone amp

[Chud17]

Question... If I unplug one of my RCAs connected to the back of my headphone amp why do I still get sound in both ears???? It does this with both left and right RCAs. Any help would be great. It does have a Linkwiz crossfeed circuit also. Thanks Bob

You answered your own question.
The crossfeed circuit sends some of the R to the L (after processing), and vice versa.
That's how it works. See figure 2 here:

Thanks Rayma for your answer. I had no idea about about the circuit and its function. Much appreciated!!!!!!
