Default Powered Mixer (no gain knob)

I acquired a powered mixer in a trade that I want to use. I normally gain stage as one of the first steps.

Its a Yamaha EMX5112SC unit, and all it has is "level" on each chanel. Other than that it has a master volume over by the main EQ and mon EQ.

Just curious on how to set gain so I dont clip, have enough headroom, etc...

you can't ...short of using resistive pads to reduce gain or gain blocks to increase gain...


other then that source distance to mike is the only other means of "level control".

In principle use Master Volume on 10 or at least on 7 or higher and then use individual "level" pots as needed.

Yamaha is an experienced Company and I bet they set each channel input stage gain (which you canīt control) to a sensible value which fits most "normal" cases.

IF one source is so hot it clips mixer input even with channel Level set to a low value, then youīll need to attenuate just that particular source, with a fixed resistive divider or lowering its gain or volume control.

No need to mess with Yamaha mixer.

By the way, I guess itīs an EMX512, not 5112

Useful little mixer.
The mic/line switch adjusts the gain to be optimal and there is no gain control as it is not required on this budget mixer.

Individual gain control is really needed when source can go from a Rock singer swallowing the microphone to a Classical Guitar player with a microphone 6 to 9 feet away, but in a Box mixer, I bet they preset it to Rock levels, not easy to overdrive
