simple question on the simple mixer… as far as I understand, pro-desks use LOG pots to compensate for the progression on the decibel scale and provide a closer to linear control of the signal amplitude. The Simple Mixer states LIN pots. Am i misunderstanding, or would it be better with LOG pots? Rob ---

if you have some log you can use them (maybe better), I have lin on all my diy mixers and it suits me like that ---

Yeah, I like audio taper better for audio 😛 ---

Keep track of which is which though-the logarithmic progression works for audio signal level, but not so good for oscillators, envelope generation, and many kinds of attenuation. ---

Mixers don’t have to be exclusively for audio. In fact you could build one with log pots for audio and one with linear pots for CV. ---

a stupid question : i don’t know audio taper, is another name the same for Log ? ---

Yeah, they’re usually marked A for Audio. They’re neither audio (as in [human hearing response curves](https://en.wikipedia.org/wiki/Equal-loudness_contour)) nor [log](https://en.wikipedia.org/wiki/Logarithm#/media/File:Logarithm_plots.png), but rather piecewise linear, but that’s electronics conventions for you. ![image](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/2X/7/74d629937b3367c8bfff32d6d120465d8e4c1c99.png) Note the V curve, btw – the alps potentiometers I got that graph from use a mostly linear curve for their volume control, not the textbook “log” curve. See [here](https://tech.alpsalpine.com/prod/e/pdf/potentiometer/taper.pdf) for a few more variants. ---

yes i know A Log and B Lin but i do not know Taper, thanks ! ---

So, in answer then… It woudl be better with (LOG / A / Taper)… But it’s not a big issue… But avoid using them elsewhere ( Been there, been stung ). I have a few LOG sliders that have no use to me generaly so will put them to good use 🙂 Rob
