My goal is to have a stage setup utilizing my new Line6 equipment while tying in some existing equipment. I need to amplify my guitar, a keyboard and 3 mic's. I have a Variax into an hd500x. Our band has a small mixer. My thought is variax into 500x into one of the L2m's via L6. I'd then send our mic's and the keyboard out from our mixer into the same L2m via the Line input jack. I was then thinking to link the two L2m's via L6 cable. I've done some preliminary setup and am finding that there is no way to adjust the level of my hd500x output via that L6 link to essentially mix my guitar in with the vocal/keys mix. I can obviously adjust my guitar level via my volume knob and the volume pedal but wondered if there is a way to adjust what I'm calling the output level of my guitar. Is the only way to adjust that via the level knob on the L2m? If so, I think I can get my vocal/keys mix mixed with the guitar level but it's not quite how I envisioned it.
Lastly, am I way off? Should I be considering it differently with a different configuration? Please keep in mind I don't want to spend money on something else (like the stagescape mixer) at this point.
Thanks in advance for any thoughts.
