iFi USB Audio Class 2.0 driver download and installation
Apple macOS and Linux support USB audio class 2 natively, hence no driver is needed.
Windows 7/8/8.1/10 driver installation process:
Please manually uninstall all previous XMOS related drivers (XMOS, AMR, iFi or from other vendors) and reboot the computer before installing this latest driver. Depending on the computer hardware, you may have to reinstall the driver again if the USB port to which the iFi USB Audio device is attached is changed.
- Download the driver file: iFi (by AMR) HD USB Audio Driver 3.2.exe
(In some instances it may be necessary to disable the antivirus software to install this driver.) - Run the “iFi (by AMR) HD USB Audio Driver 3.2.exe” file you downloaded.
- Follow the on screen instructions and ensure the iFi equipment is plugged in.
Tips:
- To use the newly installed driver, under “Control Panel > Hardware and Sound > Sound”, select “iFi (by AMR) HD + USB Audio”.
- For software players that support ASIO and/or WASAPI interfaces, we recommend using those interfaces for the best sound. Please refer to each individual player’s instructions for details.
This V3.2 driver update contains improvements and bug fixes, including, improvements:
- New ‘automatic’ buffer setting that ensures the buffer is always correct (important for high sample rates). Optimal buffer size is no longer set by ‘trial and error’ and the sound is always the best.
Further, the maximum buffer setting was previously 8192 but now can go as high as 32,768 samples (0.74 sec ASIO Buffer @ 44.1kHz). This can help reduce disk activity and can making audio streaming more resilient if the PC has multiple uses. - Fixed: Implemented larger number of Buffers to resolve ‘not enough buffers for this sample rate Error’.
- Fixed: ASIO DSD Driver behaviour adjusted to improve compatibility with DAW Software.
This driver update contains new features, improvements and bug fixes, including the following fix: Improve Windows 8/8.1/10 compatibility. Note: Windows XP is no longer supported.
Supported products:
- micro iDAC2
- micro iDSD and BL (see note 5.1 in table)
- nano iDSD, BL and LE
- nano iOne
- Retro Stereo 50
- xDSD
- ZEN DAC
- micro iDAC (discontinued)
- micro iLINK (discontinued)
- (and AMR DP-777: www.amr-audio.co.uk)
Before proceeding, a user note:
In the event that any incompatibility issues arise with v3.2, then please download and use v2.26 (iFi (by AMR) HD USB Audio Driver 2.26.exe).
For further technical queries, please open a support ticket at https://support.ifi-audio.com/
Pro iDSD firmware download and installation
Important notes
Fi XMOS firmware Pro iDSD v2.08, dated 10 October 2019, is ready for public download.
This latest firmware v2.08 is unified and is suitable for ONLY the Pro iDSD.
Please read before upgrading firmware:
- MAC USERS: USB C will not work for firmwares, you must use a USB A port
- Do not use the following firmware on any other iFi product. Use only on the Pro iDSD.
- Firmware updates inherently carry the risk of damage to the unit and of voiding your warranty.
- As the iFi XMOS firmware is heavily customised by iFi in-house, under NO circumstances attempt to use this firmware on any other non-iFi XMOS platform.
- As with all such firmware upgrades, there is a risk of bricking your iFi product if something goes wrong during the upgrade. If your iFi product is bricked, you need to send it back to the dealer/distributor for re-flash.

Magenta is the official MQA LED colour on iFi machines. When MQA is being played on legacy machines without the magenta LED option, the LED colour will be white/yellow corresponding to the 384kHz file being played.
The actual LED colour is cosmetic – once firmware v5.30 is installed, the correct MQA filter is activated during MQA playback.

IMPORTANT
- The iFi XMOS firmware is heavily customised by iFi in-house. Under NO circumstances use this firmware on any other non-iFi XMOS platform.
- Firmware updates inherently carry risk of damage to the unit and of voiding your warranty.
- As with all firmware upgrades, there is a risk of bricking your product if something goes wrong during the upgrade process. If your iFi product is bricked, please send it back to the dealer/distributor for repair.

You may have to enable ‘Install Unknown Apps‘ on your device. You can do this by selecting ‘Settings’ and checking the ‘Allow from this source’ box.
Step 5:
Once your phone has the right to install unknown apps, you may install the Gaia Control app.
Step 6:
Once this has been installed, load up the app and allow the Gaia Control app to access photos, media and files on your device. This is how it will find the firmware update.
Step 7:
When you open the app, you can search for the unit you wish to upgrade.
If your unit is not there, then hold down the pairing button on your ZEN Blue until the LED is flashing red and blue.
Once in pairing mode, swipe down on the app to refresh the search.
When you find your unit on the app, select it and click ‘Connect BR/EDR’.
Step 8:
Once you’ve paired it with your device, you can check what firmware is installed by clicking on ‘iFi Hi-Res Audio’, top right.
