JCF recallable equipment - a neat approach (API type 500 eq)

So badass.

Josh is insane in the best way. Sounds amazing as usual. I will sing his praises from the mountain tops because he really is a tremendously creative but also pragmatic person.

They had a fully recallable console too they teased. Looked amazing.

Smart dude. Great ways to future proof the recall!

Probably uses digital pots in place of mechanical ones.

Yeah, it's cool, but with "no usb or plugins or anything" also means that if there is a hardware failure in a module with fully digital control, then it's completely useless.  

To recall using 202 modulation (AFSK modulation) then it must have an A/D built in as well.  I guess it could be included solely for this purpose, but I wonder if they use digital processing for the audio instead of actual analog signal paths?

Oofda. I hadn't realized that to decode that modem burst that it would need to covert ad/da. Great question. Is the entire audio path subject to that conversion or is there a bifurcation and a bit of the signal is continually picked off in order to do the do the settings change in real time? I'd like to know this as well.I'd like to know this as well.

i used a 550a with no low shelf option for about a year before i replaced the switch. no big deal. if that single encoder or the screen die, that JCF unit is toast until it can be fixed.

i think digital / plugin control on a fully sweepable EQ like the wes, or their 16 channel vca box for automating a small console is great. i'll take that long term risk for the usefulness / repeatability / utility. but a 550? takes about 10 seconds to recall.

The dirty little secret about automated recall, the easiest gear to recall without automation are the easiest to build an automated recall system for, switches are easier than pots and the less controls / possible positions the easier. One other secret that those of us who have lived with VCA based automation is , it’s not like a pot, there are steps, tiny steps but you start noticing it pretty quickly.

I’ll say it again let’s develop a modern universal protocol for automation/ recall so even if it becomes an orphan tech, all I need is one ancient computer and not 20!

Oh do a search API had one of the earliest EQ’s with recall the 913 I think?

Looks analog to me, has transformers in the shots. 

but probably has an AD somehow in it. It has to to do that. Or it has a hybid setup where its got a transformer output on a DA? Who knows. Someone buy one. 




The only real downside to this I think is that you can't automate it digitally like you can other digitally controlled devices. 

Still cool though. 

I find that digital hardware tends to fail more often than analog.  I think analog parts typically have a much wider range of operating voltages so they tend to survive oddball situations. Digital stuff tends to have very low tolerances for voltage variations, so something like a power surge might not damage an opamp rated at 36V but running at 24V but a MCU running at 3.3V might die quickly when it sees 4V, etc.  

Just my opinion. 

I have a bunch of stuff from Josh and it is stellar! I have no doubt this is great and dammit if I might have to order some....
