Greetings L6 Kin.
Last week I tried to do a dual tone to record my acoustic-electric guitar.
Tone 1 input is direct from my guitar.
Tone 2 input is XLR from my phantom power for my Rode mic.
I could only get Tone 1. I have read and re-read the manual and watched the You tube videos several times.
I record with the Rode mic all the time. I do lots of vocals using X3Live from my phantom power box to X3L with no issues.
Suggestions appreciated :)
