I am a Lexicon Alpha user and currently, I am trying to connect an XLR cable in the input 2 so I can record vocals and record directly from my cabinet. Even though I can monitor through my headphones and confirm that the cable and microphones are working fine, when I try to record anything it just doesn't sound at all, the signal is dead, no response or whatsoever, even though I am actually listening to the sounds that the microphone produce, I am not able to record it. The software that I am using at the moment are Audacity and Cubase. The microphones that I use are a Shure SM57 and Shure SM58, both dynamic so, as far as I'm concerned, there's no phantom power needed. Has anyone had this same issue?
