I wonder if anyone knows of a very silent mixer for a home studio? I hooked up our gig mixer a Mackie ProFXP16v2 and it has an annoying hiss. The problem is not the cables or electrical source. The darn thing is just noisy. The hiss gets louder as the master is raised. It completely goes away when the volume is 'zeroed out' so we just use it on stage where the hiss is not noticeable. I would like to obtain a really quiet mixer for home use. Any help is greatly appreciated.
