I have a question for the MB Fusion/Fusion 550 users out there about the di output of these amps: How is the(post EQ) Di output level controlled? I'm about to buy one of these amps but having a hard time understanding this... By looking at the block diagram in the manual, the Di output is taken BEFORE the master volumes. That should mean that the Di level is set by the input gains, but if thats the case, then it's impossible to set a unity Di output level between a clean and a overdriven channel? After a confusing and non-informative mail conversation with GK support I ask you users directly - how does this work??
