Hi,

No, it’s only sending to channel 1 ( ch1 led light up.) From Aux 1 i’m sending in to the H90 using a Y cable stereo male <  2 x Mono jack . I’m not using Aux 2….this must be where i’m going wrong. Am i correct in assuming that I need to repeat what i’m doing on Aux 2 with In & Out 3/4 on the H90?

I hope i’m explaining things from my side properly.

Thanks.!
