Thank you for your feedback
Learn how to optimize the HDL410 system settings for your organization’s unique space. The system’s features and settings are managed using the Nureva® App and Nureva Console. It’s recommended that device settings are adjusted during a test call for optimizing performance. All device settings can be returned to the system defaults at any time.
Before starting
Set the HDL410 system as the default audio device.
Set up the Nureva App or Nureva Console cloud to manage the Nureva system.
Microphone
Configure the microphone system to be mono input or stereo input.
Mono (default) | Stereo |
|---|---|
|
|
Speakers
The Nureva App and Nureva Console offer options for setting the treble and bass outputs for HDL410 speakers. The available settings are determined by the firmware version installed on the device.
Firmware version 1.8 (or earlier) settings | Firmware version 1.9 (or later) settings |
|---|---|
|
|
Adjusting the treble and bass can affect echo-cancellation performance. It’s recommended these settings are adjusted during a test call.
Audio processing
The HDL410 system continuously auto-calibrates for optimal audio quality. Audio processing settings are available in Nureva Console cloud and they should be adjusted only if users are experiencing problems.
Echo reduction | Noise reduction |
|---|---|
Select a lower setting if remote users notice that voices in the room are cutting out. If remote users can hear their own voices echoing, select a higher setting.
| Select a lower setting if remote users notice that voices in the room are cutting out. If remote users hear background noises such as HVAC systems or fans, select a higher setting.

Calibrate
Initiate calibration when the room setup has changed significantly to quickly optimize the audio performance of a Nureva audio conferencing system.
Auxiliary ports
Aux in
Connect the auxiliary input source to be output through the HDL410 system’s speakers. The signals from the aux-in port will get mixed with any signals from a USB audio source.
Aux out
Select an auxiliary output mode for interoperability with other audio systems.
Mic level (echo-canceled microphone output at mic level)
Used for recorders and mixers
Line level (default echo-canceled microphone output at line level)
Used for external devices
Speaker out (speaker output at line level)
Used for external speakers
Mixed signal (mixed microphone and speaker signals at line level)
Used for hearing augmentation and lecture capture devices
Speaker reference
Used for acoustic tracking cameras requiring reference signals from in-room speakers
Adaptive Voice Amplification
Connect a wireless headset microphone system to the HDL410 to amplify the instructor's voice in the room. The HDL410's full-room audio pickup ensures that remote participants clearly hear all voices from the classroom.
Security
Disable the QR code access
A device setup tool is available in Nureva Console for HDL410 audio conferencing systems. Each connect module has a specific QR code. When QR code access is enabled, the device setup tool adjusts the device settings. The QR code access can be disabled to prevent access to the settings. Disabling the QR code will not limit access to the tool or the installation tips.
Integrations
Local integrations
Enable local integrations to allow the HDL410 to share sound location data with third-party systems for camera tracking and switching. Some third-party cameras will require the hostname and port number to be manually entered. This information is available in the local integrations dashboard below the toggle that enables integration. Buttons are available for copying and pasting the information into the camera software.
Camera switching
Enabling camera switching allows the sharing of data with the INOGENI CAM230 camera selector. When the following data is shared the CAM230 can automatically switch between cameras.
Default camera and triggering conditions
Sound data detected in a zone with an associated camera input
Important: The CAM230 should use firmware version 2.2 or higher and the camera switching settings must be configured on the coverage map.
Recovery
Reset audio settings
If it is necessary to return the HDL410 system to its default audio settings, pressing the Reset button will restore the audio settings to their original default setup. The HDL410 must be online and connected to the Nureva Console cloud to be remotely reset. Remotely resetting the device is not available if it is offline.
Restart device
When restarting the HDL410 system is required, Pressing the Restart button will force the device to power cycle, turning the system off and then on again. To remotely restart the system, it must be online and connected to Nureva Console cloud. Remotely restarting the device is not available if the device is offline.
