Sweepable mid range.

What do the marks on the model mixers' sweepable mid between 600 and 8k represent? For example, how does one dial it to 2k or 4k etc?

I don’t know the technical specifications, and I’m not one of the “smart guys“ on the forum here.
But typically, a frequency knob will be “logarithmic“ rather than linear, meaning that each “o’clock“ between lines is a greater change, the higher you go in the frequency, spectrum.
For example: going from the very bottom of the control (600hZ) up to the next line may only take you up to 8-900 hZ; but at the top (8K hZ), going down one line may drop you as much as 1500-2000hZ…

Thank you!

Hmm. Perhaps I could try that

I don't own one or these mixers, but it seems to me the easiest way to correlate the sweep knob marks with specific frequencies would be to;
* connect the mixer to a D.A.W.;
* load a frequency analyzer plugin;
* send a steady level white noise signal from the mixer to the D.A.W.;
* sweep the mid range;
* observe the result; and
* correlate the observations with the markings on the sweep knob.

If you perform this test, please report the results here. I think that would be a good addition to the knowledge base.

@HighAndDry,
looks like we crossed while I was editing.
