Try this test with shorted input.
Also: I assume the Behringer only has balanced inputs. When using these
in unbalanced mode (or sometimes even floating mode), distortion and/or
noise can increase dramatically. This depends on the structure of the
input circuitry before the AD chip. Another balanced - unbalanced
problem can be found on the output. Depending on the architecture, you
would be better of using pen 2 and 1 only or short pen 3 to pen 1.
I guess experimentation is the best way to find out for your situation.
