Hello, hope all is well. I'm new here and new to the dm 4800. I just set it up 2days ago and I've been able to pretty much get the machine up and running with my reading and research. My question is how can i configure the head phones for each individual musician. for example, i have a drummer and he asks me for more bass audio in his head phones and less guitar, then the guitarists says i need less vocals, the bass also says he needs less guitar. Ive been looking all over on line and theres literally nothing i can find. I have printed the manual and will be reading it tmrw so please no read the manual responses, i simply need a step by step if anyone has the time to help thanx in advance.
