Gold said:If the EQ has pots than a 13mm knob is probably fine. In that case a 2RU panel would work. For rotary switches I think you need at least 3RU for larger knobs and more text.
JohnRoberts said:It depends on how you plan to use it, this will also influence relative size of knobs and spacing. Boost/cut will be most used, so needs to be handy, center frequency next, and q last. There have been some nice mixed implementation with a slide pot for boost/cut and rotaries for the CF and Q.
If you plan to use this a lot, give it the panel real estate it deserves. If this is going to be a set it and forget it application, like for corrective room EQ, it's ok to cramp it up.
Parametric EQ has many applications so no single answer for all. Do you need to read accurate panel markings, or plan to tweak by ear, with no need to return to previous settings? This too will influence real estate dedicated to controls.

Gold said:You should take a look at the Maselec EQ. It is like what you describe. It's a very clean and functional layout. I've been using one for close to 15 years. Some don't like the sound of them but I've never heard anyone complain about the ergonomics.
ppa said:Regarding the bands ,Maselec and Massemburg EQ have a very large range to set FC .
I think that is better having an 1:10 or 1:12 FC range just as does the amek 2500, to have better precision and recall, instead the 1:40 of Massemburg and Maselec, because, however, with 1:10 range and with 4 bands is possible to cover the audio band very good. Comments are very welcome.
JohnRoberts said:Agreed, but you can also add 10x range expander by switching in different caps. That way you can have both decent resolution and wide adjustment range.
If you are using SVF with grounded inverters, I like to use the frequency pot approach where pot wiper goes full off (to ground) and you shunt the whole thing with a fixed resistor to set LF end, that way you have good fixed resistor tolerance frequency precision at both frequency extremes, and pot is used purely ratio-metrically.

yes, I use SVF with grounded inverters, I use a dual linear pot with two fixed 1% resistors to have a semi-reverse log curve, so the high frequencies of the same band can be set better than like a reverse log pot can do.

The Maselec is all switched so there is no issue with precision or recall. The Massenburg comes with pots on the 8200 and switches on the 9500.
The big advantage of he 1:40 approach is that you can work on two nearby frequencies using 2 separate bands. For example I might want to cut 1K and boost 2K, the 1:40 approach allows this using 2 bands where a 1:10 might restrict access to certain close frequency bands if each band has a dedicated range.
Are you making your eq with pots?
