converting outboard to eurorack

Post by tunnelsurf » Sun Dec 18, 2016 6:50 pm

wanted to gain some knowledge into this.

is there a way to clone a pcb board of an outboard piece of gear and make a smaller one to fit into eurorack?

ultimately trying to converting some outboard gear into eurorack

Yes.
What PCB you are thinking of?

Yes it's called 500 series :hihi:

Joking aside it can be done but you'll run into trouble with power. Some outboard will be fine on eurorack +-12v, most won't and will need higher power rails.

Offcourse. It depends on the depth of your rack.
I Allways use full "Eurocard" cases so I have 160mm depth.
This makes it possible to "fold up" sections of clones of a pcb into a sandwich using stackers.

if you have any mic preamps that have 48v then you will need 48v in the euro case. the rack gear with lots of transformers will be problematic. even when there is no 48v, the rack gear being professional quality will have +/-15v mostly. I think you should try 500 series. sell your gear and buy 500 format modules that are very similar to your rack gear. or just buy smaller rack gear. there are 1U octal mic pres available.

Most of those preamp circuits are simple and small enough to make on perfboard - just a couple opamps and maybe a transistor pair if it's anything like the tascam schematics I've looked at.

That's a good idea and you'll get a lot of support here in this community.

I recently found a useful compilation of schematics of RANE products here.
For example a microphone preamplifier with gain and tone control like this:
