I currently own the Elektron A4 MKII, AR MKII and OT MKII as well as the Minitaur.
All of the Elektron boxes require 12V DC 2A (using the PSU-3b), the Minitaur requires 12V DC 1.2A.
Now I’m trying to organise my small Studio and deal with the cable mess (spaghetti monster).
Instead of running multiple 12V PSU, I would rather prefer to have only one PSU unit and use splitter cables:
You dont need anything to regulate each device. They will only draw the current they require to run.
If all 4 devices are same 12V then all good as long as PSU can supply the current. (7200A u say, I presume you mean 7.2A). So any 12V supply that can supply above 7.2A will suit you. I would go for one like you said with a bit extra headroom.
Make sure the adaptor/splitter can handle 7.2A as well. If all boxes are on the full current will be flowing through the single end.
Just make sure polarity is same as unit. Usually center pin is positive but not always. Sure elektrons are but double check and also double check the other units.
With pedal boards this approach is quite usual, because the devices are small and all next to each other.
But with larger devices I’m not so sure if it helps to reduces much of the cable mess and with pre-made splitter cables you are quite restricted how your devices are positioned to each other.
I‘m just gonna complicate things a bit further with some hearsay.
Once had a cheap power supply for my volcas and daisy chained them together. Polarity, voltage and current all seemed fine, but it turned out the unit didn‘t deliver a clean enough DC voltage and introduced a high pitched tone into the audio of the volcas.
Got another, more expensive power supply with more outputs and galvanic isolation and everything and then they sounded clean.
Ok, thank you for the advice. I’m pretty sure the Minitaur also has positive polarity but will double-check.
Yes, was a typo =). Just a 1000x factor oops.
Not sure what you mean by controller/regulator as it’s DC, just plug it in, done!
Ok, I just wanted to double-check that. Thinking that maybe multiple devices draining current from the same unit could have bad repercussions on audio.
I will post a brief description of my setup once it’s done.
I already have such splitters: 1:4 and 1:5. The only thing I missed in the first place was that Elektron requires a 2.1 mm DC barel so I had to buy a 2.1mm to 2.5mm adapter.
I already have stands for my Elektrons and plan to drill holes in my desk for audio, midi and power cables to keep stuff clean as possible.
just created an account to follow this thread. this is exactly what i want to do.
rytm and analog drive in one case together (maybe a tiny mixer) and keytstep and digitakt in one case (using the digitakt a bit different, cause i already have a rytm…) for my live setup, more or less to make it plug&play (audio jack and maybe just 1 power connector).
+1 to hear about the results of the above projects! Anyone else have a good solution for powering allt the elektrons without lugging a huge powerstrip?
Currently rolling with this approach, which is super mobile and lean but prob not that safe
