Pedalboard isolated power supply 12V 1.7 amp requirement

[DrThumpenstein]

I'm looking to expand my pedal board and add an isolated power supply. Problem: I have a Markbass Compressore that needs a 12 volt 1.7 amp power supply. I don't mind the "buy once cry once" strategy, but I'm only coming up with one option that works off the rack: a Cioks DC7 with a Cioks Crux 24 plugged into the 24V port for around 300 bucks. I have 6 pedals that need power, and none of the others have special needs.

I love the Compressore, which is always on, tube-based, and serves my needs perfectly well. So I have no interest in one possible solution, finding a compressor that does not require as much current. I'm not sure about bridging options, etc.

One thing I do know: there are plenty of folks on Talkbass who know more about this than me and might be able to help find more cost-effective solutions if they're out there. Thanks for reading!

Cioks DC7 can do it with the right cables.

Article: Custom Boards' guide to power supplies - Cioks.

Excerpt:

"
The Neural DSP Quad Cortex runs at 12 volts, with its own power supply dishing out a whopping three amperes into a regular "Boss-standard" plug. According to Neural's engineers you can run the Quad Cortex safely using "only" 1.5 to 2 amps.

To achieve this you can combine four Cioks DC7, Cioks 4 or Cioks 8 outputs using three Invalid Link Removed, as seen in the picture. Connect the final output to a regular Cioks DC-cable with a regular 2.1 mm connector to the Quad Cortex. All of the PSU-outputs must be set to 12 V.

I like/use Cioks, so you can't go wrong and would have options for what came in the future.

I did however see that Walrus has another power supply coming that has a high amperage output on it for these types of pedals. It only has three other outlets, but since your pedals don't require anything out of the ordinary you could daisy chain a couple of them. $229

Canvas Power HP

*All Canvas Power HP - US Power Supplies will begin shipping 8/20* The Canvas Power HP allows you power the thirstiest of modelers and pedals with a massive 3A (three Amp, or 3,000mA) output. The HP also has 3 isolated power outputs delivering up to 500mA of clean power at 9v. The 3A output can...

Thanks for those responses, saving me $ already! I'll take a $5 cable over a $70 adapter for the same results!

I just learned that even though the OEM power supply is 1.7 A, the Compressore actually only requires a minimum of 600 mA, so that lowers the bar a bit. I'd just need the cable to combine 2 of the 12 V ports.

There's a local used Voodoo Labs 4X4 with a board that's just the right size for a decent price, and Voodoo also has a current doubler.

I had a Markbass Compressore on my board for a few years. It's one of those pedals I should've kept. My board was powered by a VooDoo Lab Pedal Power 2+. I simply just used the 110v power outlet on the VooDoo Lab to power the Compressore's wall wort PS and secured it with a zip tie. Very convenient and doing it that way left all 8 ports available for everything else.

Some power supplies have a 110v outlet which is a nice feature to have on a pedalboard. Also, some have a USB port which can be handy at times.

I use the Compressore. I just use the power supply that came with it, plugged into a power strip i attached to my board

Late to the party but glad you found out you need less power draw than originally thought. I use a VL 2plus and can run my 2 strymons as well as it having an extra power plug that I can run a wall wart (or a 1 spot for even more options). It powers the SushiBox tube pedals just fine as well so a vote for Voodoo Labs!

Markbass Compressore requires 600mA at 12V technically. Cioks is known to provide 500mA at 12V but actually it can go as high as 570mA which ends up being more than enough for tube compressors or compressors with tube stages including but not limited to Markbass Compressore or Effectrode PC-2A. I am not sure where got the 1.7A current draw information... Even though it says minimum 600mA for different versions of the Compressore as per the following links, it draws less than that around 550-570mA.

I've actually had two Compressores and have both of their power supplies, both of which are 1.7 A, so I thought that was the requirement. I posted above that I was wrong, but thanks for pointing that out. I know tube pedals can get a little extra grind when they're underpowered, but that's not really what I'm going for here.

I lucked into a nice Voodoo Labs board with built-in 4 x 4, plenty of ports for what I've got, with a couple to spare. I've got the VL connector cable coming to use two 12 V circuits to run the Compressore. I'll be able to run the 4 on the Floor at 12 V, which is fine. Truthfully, the differences between 9 and 18 V on that pedal are subtle and with a little rotation of the dials, essentially unimportant, IMO. Everything else has a low current draw and I'll have a couple of ports I'm not using in case something else comes along.

Again, thanks to everyone for helping me get this sorted out! Pics when I get it loaded.

And, I stand corrected: that power supply (Compressore) says 1.5 A rather than 1.7. When will I just go ahead and admit I need readers?

Here's my fly new ride:

Plugged in, everything works, although I'm waiting for the current doubler adapter. And a shorter right-angled TS cable between the Qtron and the 4 on the Floor. Silent so far, as expected.

Hi mate,
I run my Markbass Compressor from just one output of my Cioks Sol. Give it time to warm up ~30s and it's totally fine,

I apologize I did not realize you pointing out the following. Hope this was not mentioned above but the power supply that comes with the Compressore has tones of headroom; yet it is not what it actually supplies but rather what it is capable of supplying. After switching to Cioks from VoodooLab, I have more flexibility and because of the form factor it is much easier to install Cioks on different pedal boards. Highly recommended! If you want to feel more comfortable there is always the gray current doubler cable for Cioks where you have to dedicate two outlets.

Best…

Just wanted to add for OP or anyone else who stumbled onto this thread via Google, as I did - I've got a Truetone CS6 on my board, and I didn't notice the power requirements of the Compressore until after I'd already put everything together. I wrote to Truetone's customer support to see if they had a solution since the CS6 has two 12V 200mA outputs and a few 9V 500mA outputs. They said that the mA rating on the CS6 is incredibly conservative and that it shouldn't be a problem to just run it off one of the 12V outlets. I recorded a few takes with both active and passive basses through the Compressore using both the supplied Markbass power supply and a single 12V 200mA outlet on the CS6 and cannot hear any difference in tone, volume, noise, or anything else. They sound identical to my ears.

Just tossing this one out to anyone looking in the future.
