Ken, during the recent past I also worked in professional audio and my biggest peeve was the lack of what I prefer to call a “minimal” mixer, that simply mixed. The only add-ons I wanted were at the front end, adjustable pads to compensate for the wide output velocities of different microphones and different applications (i.e., brass is loud, maybe a flute might be very soft). Also balanced in and out was desired. But ALL the mixers are crammed with all kinds of EQ knobs that mostly get mis-set by accident or by an operator who wants all bass. I did not find the right mixer at that time.
Now in my truly minimalist radio station I have a Radio Shack 32-2056 Mixer ($40) which is very basic. four-channels mono and two channels stereo, unbalanced. I added my own pads and matching transformers and love it for voice. It would sound good for music too, but it would take an active engineer to carefully watch input velocities and clipping. It also mixes line levels.
If Radio Shack knew it, they could promote this mixer for on-line radio and probably part 15 stations too, but I think their focus is on tiny telephone devices.
