please post.

Professional equipment doesn't say "Pro" on the box. Whenever you see
"Pro" on the box, you can believe that it's amateur gear.

What you describe is probably noise on the grounds from the effects
processor leaking into other stages. Odds are that if you put a
microphone on an input, it won't be quite so loud. Just mute unused
channels.

This is the absolute cheapest bargain basement gear. You should be pleased
that it works at all given how cheaply it is made.

It might be possible for a technician to add some additional decoupling
capacitors around the effects system to quiet the grounds and rails down.
But it's really not worth the trouble to work on equipment this cheap
because as soon as you fix one thing, you notice something else.
