I have purchased a Focusrite 18i8 2nd gen, so far everything seems to work except the monitor output.
I have a set of powered speaker plus subwoofer from Sony, they are a set of old speakers that I am using as monitor speakers. The audio cable has a stereo 3.5 mm standard jack TRS
I have purchased a TRSF to TS splitter, since the monitor output is a 1/4 plug; but when I turn on the speakers, the audio goes only on the left speaker, and it sound like both left and right channel are playing on the left speaker only. I tried to connect the same speakers through the headphones output, and it works just fine; so I can say that the speakers are not broken.
At this point, either the monitor connectors on the interface are busted, or the splitter I am using is not working correctly. I used a different splitter, same exact type, and it still does the same as the other cable.
I don't understand where the problem is. The monitor output are 2 mono channels for L and R, so the cable I use is correct, because it is a TRS female to TS male L and R. Any suggestion?
