Product information

What is Nucleus?

At the heart of every Roon system is a Roon Core. This is the brain behind the entire Roon experience – it manages your music collection, streams to your audio devices, and stores the Roon database. Nucleus was developed by the Roon team to provide a silent, high-performance, power-efficient appliance to host the Roon Core. Every aspect of the hardware, operating system, and software is optimized to make Nucleus the very best way to run Roon.

Roon account

Nucleus requires a Roon account with a valid subscription, which you can purchase at

If you're trying Roon for the first time, getting started is a snap. Just connect and power up Nucleus, install the Roon or Roon Remote app on your devices, sign up for a Roon account, and you're all set. If you already use Roon on another device, there's one extra (optional) step: Nucleus will take the place of your existing Roon Core, so you can migrate your Roon database from the computer you're using now to your Nucleus, or you can start from scratch.

Controlling Nucleus

Nucleus has no display or interactive components. To experience Roon, you will use the Roon app on a Mac or Windows PC, or the Roon Remote app for iPad, iPhone, or Android devices. Note: Only Mac, Windows, and tablets provide access to all of Roon's features. Due to their smaller screens, the Roon Remote app on phones has a limited feature set.

Playing audio

There are three ways to use Nucleus to play audio, and you can use any or all of these at the same time. The first is connecting an integrated audio component, DAC, or headphone amp via one of the two USB ports. The second is to use the HDMI port to connect to an audio/video receiver (AVR) or other device which supports multi-channel audio over HDMI. The third (and most flexible) is to stream to your audio device(s) over your network; Nucleus supports many different types of networked audio devices, including Roon Ready products.

Storing your music files

Nucleus can manage your music files three different ways, and you're free to mix and match these as well. The first is to connect an external hard disk drive (HDD) or solid state drive (SSD) via USB. The second is to install an optional internal HDD or SSD. The third is to store your files on a network attached storage (NAS) device, which Nucleus will access over your network.
