Guide to Selecting USB Profiles on the Extreme Music Server

Step 1: Look up your DAC in the DAC list to find the ideal USB profile

Consult the list below to find your specific DAC model. Note the recommended USB profile and Roon bit-setting for optimal performance.

Note: DACs listed in black are part of the initially installed Taiko USB Driver. DACs in blue are later additions, available only in specific driver versions for users who requested them. For new DACs or those not on this list, please contact Taiko Audio support at support@taikoaudio.com.

Step 2: Make a VNC remote desktop connection to your Music Server

This step involves connecting to your Music Server's desktop environment remotely.

Tip:

If you have previously accessed the server's desktop and its IP address has not changed, you can proceed directly to Step 4.

1. Download the VNC Viewer application on a device connected to the same WiFi network as the server. You can find the app at: https://www.realvnc.com/en/connect/download/viewer/
2. Run the VNC Viewer app.
3. Click the '+' symbol in the top-right corner to create a new connection profile.
4. Tip: The server's IP address can be found within the Roon application.
5. Enter the server's IP address and assign a descriptive name to the connection profile.
6. Click 'Save' to store the profile.
7. Select the newly created connection profile.
8. Click 'Connect'.
9. Tip: If you do not know the VNC username and password for the server, please contact your supplier.
10. Enter the VNC username and password for the server.
11. Select the 'Remember password' option.
12. Click 'Continue'.

The server's desktop will now be displayed and can be controlled remotely. You can enable a virtual keyboard by clicking the keyboard icon ⌨️ in the toolbar at the top of the screen if needed.

Alternative method (macOS only):

If you are using a macOS device, you can also access the server's desktop via your web browser:

1. Open your web browser.
2. In the search bar, type vnc:// followed by the server's IP address (e.g., vnc://192.168.1.23).
3. A popup will appear asking if you want to open the screen sharing application. Click 'Yes'.
4. Tip: If you do not know the server's password, please contact your supplier.
5. Enter the server's password.
6. Press 'Enter'.

The server's desktop will be displayed and can now be controlled. A virtual keyboard is available via the keyboard icon ⌨️ in the toolbar if needed.

Step 3: Execute the selected profile by right-clicking it and selecting "Run with Powershell"

Note: Executing a profile will immediately reboot the Extreme Music Server.

The server's desktop will display a range of USB Profiles. Locate the profile that is ideal for your DAC. Right-click on the selected profile and choose 'Run with PowerShell' to execute it. After the reboot, the profile will be active and will remain so through subsequent reboots and changes between Roon and TAS.

Step 4: Select the appropriate output bit rate in Roon

This step ensures that the correct bit rate, as identified in Step 1, is set within Roon.

1. Navigate to 'Settings' (1).
2. Select the 'Audio' page (2).
3. Locate your main audio zone, typically named 'Taiko Audio USB Audio Device'.
4. Click the gear icon ⚙️ on the right side of your audio zone and select 'Device Setup' (4).
5. In the pop-up window, click 'Show Advanced' (5).
6. Scroll down to the 'Max bits per sample (PCM)' setting.
7. From the list of available bitrates (6), select the one you noted earlier from the DAC list (7).
8. Click 'Save' to apply the changes.

To change the USB profile later, simply repeat these steps. A new Remote Control app is under development that will allow switching DAC profiles directly, without needing a remote desktop connection.

Step 5: Setting TAS Buffers (only required if you have TAS installed)

As part of a recent update to the OS and USB driver, Roon is now the default music player on system startup. To use TAS, you must launch the TAS remote app on your phone or tablet and switch to TAS.

Part of TAS has been integrated into the new USB driver, resulting in significant sonic benefits when using Roon. Consequently, one setting within TAS needs adjustment even when using Roon.

To access the player settings screen:

• Tap and hold your finger on the green player button. The relevant settings screen will open.
• Tap 'Output Device Selection' and ensure the appropriate ASIO device is selected.
• If your DAC requires DOP (DSD over PCM), select it here.
• Choose your USB buffer sizes for PCM and DSD.
• Set the TAS buffers to 'Auto'.
• Tap the top-left arrow to save your changes and exit.
