1. Where can I download Devialet Air®

Devialet Air® is available from your account under the tab "Expert Configuration". You can access the login page here

Then browse through this section of your profile : you will find every software from Devialet.


Please select Devialet Air® for the type of computer you are looking to use it on (Mac Os or Windows).

When the download is complete, launch the set up for Devialet Air® application and follow the instructions during the setup.






2. How does Devialet Air® work?


To set it up you first need to create your own configuration via our Online configurator which is available here. Your Expert needs to be set up on your network.

Note: We strongly recommend that you log into your profile before creating a new configuration in order to keep this configuration saved on your profile. This will give you the possibility to change it whenever necessary.



Devialet Air® is software that treats your Expert product as an extension of your computer. This means that your Expert will function as the speaker for your computer. Once connected to your Devialet via Devialet Air®, any music you play on your computer will also be played through your Expert. From a driver's perspective, Devialet Air® functions like a sound card, offering both wireless and wired connections to your Expert System.

Devialet Air® is only available for computers. There is no tablet version or mobile version.


A - Wifi settings

To configure your WiFi, you will need to fill in the following items in your configuration:

Device Name: the name of your device once connected to your network

Name (SSID): your network name 

Password (Key): the password associated with your Wifi.


Note: Non-Pro Expert are not able to connect to a 5 GHz WiFi, so please make sure that you have a 2.4 GHz wifi available and set into your configuration. This limitation has been fixed with the Pro model of Expert.

Note: The password for the WIFi network has two limitations : it's limited to 30 characters and it should not contain any special characters (for example *,/,'é etc...). 

Note: Ensure your Wifi router is not set with MAC Address limitation. Your MAC Address is available when your device is connected to the network via Devialet Air® in “Device settings” (in this case you will need to wire your device with ethernet in order to view it in the network and get the possibility to find out the MAC Address).



B - Ethernet settings

On ethernet there is no specification required.

We recommend this mode as it offers the most stable connection and ensures high-resolution tracks are delivered to the Expert device without any signal degradation




C - Difference between Non-pro and Expert Pro.

With the non-Pro version of the Expert, if you configure both Ethernet and WiFi connections on your Expert, both options will be available as a source for your Expert.

In the Expert Pro range, we primarily view these two protocols as channels for delivering sound to your Expert Pro, and as such, there is no specific source associated with these protocols

In any case, Ethernet will always take priority in an Expert Pro. This means that if you have configured both options and your Expert is connected via Ethernet, the WiFi connection won't be used.

Additionally, if you did not configure Ethernet on a Expert Pro, and you wired your device via Ethernet, your Expert will automatically use that as the protocol.



3. All is set, what should I do now?


If you followed all the above instructions, you will then have connected your Expert to Devialet Air®.

Here are the next steps : 

  1. Select the right source on your Amplifier (Ethernet or Wifi) for non-pro devices. To do this, use the "Source" button of your Remote. (Note: for Pro devices, this not required as Devialet Air® will automatically switch your amplifier to the right source).
  2. Launch Devialet Air®

6. Questions & Answers

  • Do I need to install Devialet Air® if I play music via USB?

No, Devialet Air® does not require playing through USB. You are able to install a specific driver to enable this on your computer.. On Windows, the driver is available in the Expert Configuration section of your profile. To set it up, you need to connect your computer to your Expert using a wired connection.

The required USB cable must be a cable with A-MALE AND B-MALE ends.

Our recommendation is to use a genuine High Speed 480Mbps USB 2.0 cable, no longer than 2m (6.5'). 

Recommendation: For the best installation, it is preferable to avoid using a repeater or a USB hub between your computer and your Expert. Only use the USB ports directly connected to the computer's motherboard.



  • When I launch Devialet Air®, I have an error message saying “Sound Card Driver could not be loaded”.

Devialet Air® 3.0.4 can generate a specific error message when launching it on a Windows PC. The error message is "The Air Virtual Sound card Driver could not be loaded". In order to allow Devialet Air® to be launched properly, we suggest you disable the secure boot on your BIOS.

You can find the steps to follow on the website of your PC’s manufacturer, otherwise, you can follow steps on the Microsoft Website


ame error can happen on  MacOS. Here are the steps to address this error:

  • Go into System Preferences
  • Select Security & Privacy
  • In the options you will find "System software from developer "Devialet SAS" was blocked from loading" Click on the Allow button.
  • If this button has disappeared (which is the case about 1 hour after the Devialet Air® Installation), hold the Control button of your keyboard, and click on the Devialet Icon
  • Select the option "Open". The error message will appear again.
  • Return to Security & Privacy, the "Allow" button will re-appear.



  • How Can I play tracks from my NAS to Devialet Air®?

Apart from the options available with Core Infinity, such as UPnP, Devialet Air® can also be used in your specific setup.For this, you will need to use a player which is able to find and play tracks from your NAS server to your computer (some mentioned in the section 5 of this article could be a perfect match here). Devialet Air® is transmitting the signal to your Expert as it is with no upsampling or downsampling - the core audio of your computer is bypassed in this type of setup.



  • I've been told that Roon onboarded Devialet Air® - what does it mean?

Our partner Roon has worked to integrate Devialet Air® directly within Roon, enabling you to stream directly to your Expert (when it is available on the network).

As a customer, it also means that you don't have to setup Devialet Air® if you want to use Roon with your Expert, you will only have to setup the Devialet Air® option in Roon (options are available in the "Settings"/"Audio" menu - all DSP options are also available from there).



  • What are Devialet's recommandations when it comes to network setup for Air®?

Devialet Air®’s ability to stream properly is mainly linked to two specific variables:

  1. Strength of your network
  2. Your computer Core and its usage while streaming.

When it comes to the network, the best way to deliver a good signal to your Expert will be to wire your amplifier to your main or satellite router via Ethernet. Quality will also depend on the available bandwidth while you are streaming. 

Wifi is also a good option, but generally domestic wifi has a lot of interference from home devices that might use the wifi connection. However you can still set a separate network for your streaming session via an additional router which will generate its own SSID only used for your Expert streaming. 

To get help for setting up this type of dedicated network, please consult our Customer Care.

Regarding using your computer while streaming, we recommend keeping it at a minimum running process on the source device (Computer) and keep the Player as the only software running. A lot of our customers use a dedicated computer for the streaming, in order to avoid diminished sound quality while streaming.



  • What are the minimum requirements for setting up Devialet Air®?

Devialet Air® 3.xx requires :

  • Yosemite MacOS or Above
  • Windows 7.0 or Above

Devialet Air® is not supported on your computer if it is running an OS version older than this.


  • Can I play DSD with Devialet Air®?

 DSD stands for Direct Stream Digital and it is a specific format of digital tracks. 

You can find more details HERE.

To play DSD files, we recommend you use the USB input of your Expert product. In view of the size of content on a DSD format, Devialet Air® likely won't be able to stream music in this format smoothly.


  • Can Devialet Air® be used with the more recent versions of MacOS ?

We released a version of Devialet Air® that can be used with Catalina, Big Sur and Monterey. It is available for download on your account, under the "Expert Configuration" section. Any other recent version of MacOS is currently not supported.


  • How to uninstall Devialet Air®

On Windows : In the directory where Devialet Air® is installed, launch ‘unins000.exe’. This will uninstall the software.

On MacOS : In the “App” menu, find the Devialet Air® icon. Drag it to the bin in the Mac taskbar to uninstall the software.
