Make Noise 4 Zone CV Bus Case

Make Noise has introduced the 4 Zone CV Bus Case, a powerful Eurorack case offering two 104 hp 3U rows for Eurorack modules, one 104hp 1U row fitted w/ CV Bus, premium build quality and more.

The powder coated metal construction is designed to offer excellent mechanical durability. The lid is removable and can be closed with the system fully patched.

The Make Noise 4 Zone Power Bus Board is like having 4 independent bus boards, in a convenient single bus board package. Each Zone features isolated +12 VDC and -12VDC supplies and a dedicated ground return path. The +5VDC supply is shared amongst all 4 zones.

The multiple section of the CV Bus was originally designed in 2013 for Alessandro Cortini‘s personal Make Noise system. It provides visual indication of level, rate and polarity for up to 4 control signals that will be shared throughout a patch. These 4 control signals are color coded and distributed across the center of the system. The color coding and visual indication makes navigating complex patches easier and more intuitive. Typically, the CV Bus would be used to share the most important control signals in a patch such as your Master Clock.

This new version of the CV Bus also includes useful modular utilities:

  • The Voltage Math is found at the left end of the CV Bus. Like the similar circuit on the 0-Coast, it is a small collection of universally useful modular utilities. The two inputs are summed at the output, one at unity and one adjusted by the input attenu-verter. The attenuverted input is also normalled to a DC offset, for purposes of level shifting, voltage mirroring etc. The output strength and polarity is indicated by the Green and Red output LEDs.
  • A high quality Stereo Line Driver converts powerful modular synthesizer signal levels to the commonly used Line Level. There are mini-jack inputs for Left or Mono, and Right for Stereo sound, a single master volume control, as well as a stereo line output pair, and finally a TRS line/headphone out on a single jack. This output is capable of driving a long cable out to a PA System or a set of Headphones. It is AC coupled with a built-in limiting circuit (with visual indication) that prevents damage to ears and PA system when the patching gets experimental.


  • Two 104 hp 3U rows for Eurorack modules, One 104hp 1U row fitted w/ CV Bus
  • Hybrid switched/linear power solution for low noise and excellent load regulation
  • Multi-Zone, allowing isolation of noise-prone modules from noise-sensitive ones
  • Black powder coated metal w/ embossed logo on lid
  • Sealed to keep dust out during travel or storage
  • Lid offers space to close w/ your system patched
  • Recessed side mounted on/off switch and power inlet for safe travel
  • Locking power connector helps prevent on-stage power loss accidents
  • Solid carrying handle and rubber feet so the case travels w/ ease
  • Meets carry-on luggage size requirements for most airlines
  • Universal AC power adapter works world wide (Need IEC Cable for non-US outlets)
  • Blued Steel Stand sold separately

The Make Noise 4 Zone CV Bus Case is available for $949 USD.

  1. Red/Green LEDS, pass. for a ‘premium’ kit you would think they could spend a little bit more and make it work for everyone. ffs.

  2. Gimme a break with that pricing… It’s a very nice looking case. I’d love to have it. But $949 is absolutely insane.

  3. I am a bit of a Make Noise fand and have a lot of their modules in my cases, but this just seems unnecessarily expensive especially now there are now cheap high quality cases options…Behringer Eurorack Go is similar for £218!

      As a Eurorack Go owner, I have to say it’s pretty much crap compared to this.

      The Eurorack Go is a knockoff of the Tiptop Mantis, which is about $325, or a hundred buck more than the Behringer. So it’s a better comparison.

      The Eurorack Go is basically all plastic, instead of all metal. The Behringer Go doesn’t have a real handle, so it’s not designed to be a performance case or traveled with. It doesn’t have a lid, so you can’t move it patched, or take it on a plane. The Go also has an inferior power supply, and it’s really awkward to connect module power cables, if you’ve got modules in the first row.

      The Make Noise case also has the bus row and several utility modules.

      So they’re really designed for different purposes – the Behringer is a good beginner option, and the Make Noise is a pro option that’s designed to stand up to live performance and travel.

      Pro gear is ALWAYS a lot more expensive than beginner gear, because it has to be built a lot better, and it’s built for a much smaller audience.

      1. God, the Behringer shills are annoying.

        They continually complain about things that they obviously don’t understand. And then they attack anybody that appreciates good gear and call them ‘gate keepers’, ‘cork sniffers’, or even ‘dentists’. lol

        If there’s an opposite to big dick energy, they’ve got it.

  4. Intellijel and BEFACO have a 1U row more, high quality built and cost less (200/300!) – so that price is absolutely off. And this is USD – in Europe that case will cost 1300€ then but even 950 is absolutely ridiculous. What’s next.. a teenage engineering 40hp skiff for ? 1500? Wait that’s more than realistic. I always lusted for the make noise case stand though but 200 is also quite a hefty tag. So let’s assume the EU price will be 1300 – I can buy TWO befaco cases and I’m very very happy.

  5. exposed power headers, sliding nuts, the green and red leds, it all seems really cheap but then you see the price, wow, not for me

  6. Have you folks ever bought a eurorack case?

    Let’s compare this Make Noise case to it’s nearest and most comparable competitor, the Intellijel 7u 104hp Performance Case.

    Case – $699
    2 x 1U Mult – $50
    Att 1U – $20
    Headphones 1U – $70
    Stereo Line Out 1U – $70

    With the 1U row on the Intellijel Performance Case equipped with modules to approximate the functionality of the Make Noise case you’re looking at a cost of $910.

    I’m a huge fan of my Performance Case, but I can tell you without a doubt that it is the more cheaply built option of the two. The Make Noise case also has a larger (4A vs 3A +12VDC) and arguably better designed and less noisy power supply.

    Go buy your Behringer trash, but also understand that this case isn’t anywhere near as absurd in cost as you all are making it out to be.
