ok,thank you,now everything works fine,

about  the 4 channel presets matter,

you say that if i connect the analog 1 to IN3 and IN4 i can use 4 channel presets.

I would like to understand this in a better way,to use my H8000 at its best.

With my bass,for instance,using this procedure with a preset like the #6537 2xTC2290s,could I connect the analog 1 to IN1,IN2,IN3 and IN4?

also,with all the presets of the Bank #30 and #32,could I connect the analog 1 to IN1-IN8?

do I need of mulitple speakers to can listen to the outputs of these 4 and more channel presets?
