I used the A-180-9 to carry CV signals between two euroracks 6 meters apart, and it worked perfectly.
Then I tested two A-180-9 carrying stereo audio signals from a patchbay (with amps, instruments, & effects), to a mixer, a tape recorder and A/D interface, all gathered 10 meters apart from that patch bay.
So Mixer, recorder and A/D were connected to one A-180-9 with short mono cables, then the two ethernet cable (well shielded, good quality CAT 6) went across the battlefield to the other A-180-9 close to the patchbay. Good signal, no interferences, no crosstalk.
I managed just two cheap long cables on the floor instead of 14 expensive ones. For this price is ace.
