Zuma 2008
Nelson Suggs
The crux outputs max 24W (12V at 2A). The Ojai has 5 outputs (9V, 0.5A = 22.5W). So the crux is drawing more that what the zumma is designed for. Strymon did mention that the outputs can provide a bit more juice at 0.53A to account for any drops and that brings the total up to 23.85W which is still less the crux.
Strymon also mentioned that you could potentially overload the zuma if you maxed out all capacity of the outputs as well as connect an ojai and max out that too. Seeing as Im maxing out that 24V output and planning on using some other pedals I just wanted to check this is okay. I have about 15Watts worth of other pedals connects which is still below the overall power draw of the zuma (48W).
That being said, I emailed cioks and they also said that the crux is only designed for the DC7 and that they wouldnt take any responsibility or validate any warranty issues with it being used with the zuma.
TLDR: Is the cioks crux okay to use with the zumma? Neither company condones this set up or will validate the warranty and doing some quick maths, it seems like the crux is drawing what appears to be more than the design limit of the zuma. Im not an electronics engineer so maybe im doing the wrong thing entirely.
So I guess a follow up question would be: Is the heat okay? Some power bricks get hot when theyre used anyway and its just how they work. This is when i resorted to the math haha, so is the heat okay or a warning sign of the power supply struggling?
