Please note: this information is only intended for technical experts & makers. If you have not built Raspberry Pi projects before, we strongly recommend that you contact sales@jacktrip.org about purchasing pre-assembled devices instead. We are not able to provide assistance with building your own devices.
JackTrip's Raspberry Pi disk image is built to support several different sound cards, but we recommend using HiFiBerry's DAC+ ADC Pro for the best sound quality and lowest (1ms) latency, widely available at a reasonable price. We plan to make these available pre-assembled for an easy, plug-and-play experience, but you can also build your own!
Here are the parts you need:
- Raspberry Pi 4b (2GB)
- HiFiBerry DAC+ ADC Pro (standard model also works, but we think Pro is worth the extra cost)
- Steel Case for HiFiBerry ADC (White / Black)
- USB-C Power Supply (White / Black)
- MicroSD Card (32GB) (2GB or larger is fine)
One of our community members has generously shared these photos illustrating the assembly process.
It's totally fine to substitute a preferred power supply or different MicroSD cards. If PiShop is out of stock, here are a few other places to look:

I just want to thank Michael Dickey for pointing me in the right direction. And not just once. I'm not a technical expert, but after some odd misfires, I did manage to assemble my own box and - IT'S WORKING!!! Thank you!
I want to mention that the photos illustrating the assembly are annotated, you just need to click on the Info button to see all the written directions.
The second box is so much easier to build than the first.
Question: is it possible to use any of the unused ports on the assembled Jacktrip device for recording of a session by piping the audio input to a computer? It looks like all unused ports are USB and one is a 3.5mm jack, all on the Raspberry Pi itself.
If this won't work, any advice on the easiest/best way to record a session coming through the Jacktrip device? I've heard recordings that were made so hopefully some folks have already discovered good tips!
You can't use the "unused" ports for this. What I do is connect the RCA output to a FocusRite 2i2 (Presound is another great option), and then plug my headphones into it for monitoring. Then you can set your computer to use the USB device as audio input for Audacity, DAW, or even just for piping the sound into Zoom. I usually do Audacity for recording + pipe it into Zoom from the same computer/device, at the same time.
I connected all recommended parts, a Hifiberry DAC+ADC pro and a Behringer XM8500 with a high output signal but there is pretty much noise on the signal. I have to turn the input volume to 100% to get a usable signal but the noise is not acceptable. Is there a recommendation, how to proceed? I plan to integrate a mic pre-amp to get a higher input signal from the mic.
Also the output level depends on the impedance of the headphones. For me it seems that the line level output of the Hifiberry is not enough to drive a headphone. I used different models but again end up in turning the output level to 100% to get a somehow acceptable volume. An output amplifier would also enhance the usage.
When using Focusrite instead of the Hifiberry, all levels are perfect.
Michael, when you connected the Virtual Studio device RCA outputs to the Focusrite 2i2 did you use RCA to XLR or RCA to 1/4" cables?
I've used the onboard connector J4 (balanced input connector) of the hifiberry to connect the XLR differential input directly. But I did a mistake when connecting - I just recognized. Now the noise level is much better, but the output level still low. When connecting to my mixer to adapt the levels, everything is perfect, but without, there is no headroom for higher output levels.
I also tried to connect the mic direct using a XLR to 1/4 adapter, but the result is the same.
