I used to use my X Amp with my Profire2626 without issue, but I'm having trouble getting it to work with my 1818VSL. I have the DI guitars output running out of the 1818VSL on output 5: From there the output goes into the X Amp. From the X Amp output, it goes into the input of my amp: I then have the output of the preamp of my amp going into channel 3 of the 1818VSL And here is the settings for the 1818VSL's mixer: I'm getting the whole mix into the amp, not just the single DI track like I have configured. Or, if I fiddle with the settings, I get nothing but high pitched squeal. I have no clue how to fix it. I was able to fix it on the Profire and it was a bit easier...Any help is greatly appreciated.
