Hello, I put this question here in case you can help me. I own Presonus Eris 05 studio monitors and have them connected as follows: an audio interface on the XLR input, a guitar pedalboard on the TRS input and another guitar pedalboard on the RCA input. I have everything connected at the same time and I can use without disconnecting anything the pedalboard that goes through TRS or the other pedalboard that goes through RCA, I can even use them at the same time. However, if I want to hear the XLR audio interface, I have to disconnect the TRS cable from the speakers. I find it quite strange and uncomfortable, since when I want to use this interface I have to disconnect the TRS cable. This is normal? Thanks.
