I got word back from ADJ that the 14 mixer does this less but it's still there. The 10 is about the same as the 19. I don't know what to make of it. It's pretty wild. No mic attached.

As I said earlier in the thread I did get word back from ADJ.

They took the time to bench test all the units in the line. I really like their support for replicating the problem in house and responding. They are a stand up company and I'll do business with them again. But I can't use this unit as it is for the specific install I'm needing it to work on .
Hello Jeremiah,
I'm the guy who responded to your YouTube video of this mixers mic noise problem. I joined ODJT so we can continue this discussion here.
The only way to have the mic gain knob not alter the noise, is to have put the mic gain control at the INPUT side of the mic preamp. They probably did this to prevent high gain mics from overloading the mic preamps. Unfortunately, if you have sensitive loudspeakers (like most DJ's do) you are going to hear the preamps hiss.
What they should have done is had a switch selectable gain-setting (which alters the negative feedback around the mic preamp) and then had the mic gain control on the OUTPUT side of the mic preamp.
People reporting various differences of this problem(regardless whether 10, 14, or 19 model) are again being influenced by differences in speaker sensitives, plus low grade op-amps (which they are probably using) are NOT graded for noise and can vary greatly from batch to batch.

Welcome to ODJT and THANK YOU For coming here to help out with this. I'm not the only one it seems. ADJ has been great in testing the rest of the line.
A switch would have solved this. You are right. It seems like this is no-brainer for engineers. This is hiss is comparable to the worst of the worst DJ mixer mic inputs I have experienced. However ADJ support has been good and determined this mixer can't be fixed. I love honesty.
