trying to connect Lexicon MX200 to allen & heath 32 channel mixer console. console has 6 aux sends, sound guy has lexicon 1/4″ ring plugged into channel 6 and other end, 2 ring and tip 1/4″ plugged into back of lexicon, channel two. He also has another line hooked into stereo channel (blue fader) and that one hooked into channel 1 of lexicon. We need another monitor outlet for or live band. he is saying no way we can have another monitor outlet. While working the board myself, when I take out the one line input cable from aux 6, effects does not change what is coming through mains. He is telling me that input cable is the send for the Lexicon component, yet nothing is happening when I unplug it. How can we resolve this? we need that aux 6 line for additional monitor on stage. Can anyone help?
