Technical training and certification

The best way to determine whether a room is suitable for a Nureva audio system is to compare the room dimensions to the recommended coverage area for each model. HDL series systems cover rooms up to 35' x 55' (10.7 x 16.8 m) while HDX series systems cover spaces up to 40' x 60' (12.2 x 18.3 m). For a quick recommendation, use the Nureva product selector. By entering details such as room size, room type and intended use, the tool can help identify the most appropriate Nureva solution for your space. Contact Nureva support if the room falls near the published coverage limits but includes unusual design challenges.

Placement is determined by use case and the room layout. Keep microphone arrays away from physical barriers and persistent noise sources. Place microphones near the locations where the most talking takes place. For HDL series systems, use a hard mounting surface, maintain the required clearance below the microphone array and keep the bar away from corners. For HDX series systems, space audio bars and microphone pods evenly for balanced coverage. HDX audio bars can be installed vertically or horizontally on a wall using the included mounting bracket or a supported VESA® mounting solution. Explore the Nureva user guide to learn more about HDX placement options.

Use a 3:2 clearance ratio below the bar. Multiply the depth of the object below the microphones by 1.5 to calculate the required vertical clearance. For example, a display that extends 3 inches from the wall needs 4.5 inches of clearance. Explore microphone clearance requirements and recommendations in more detail.

Use a backboard when the microphone and speaker bar can’t be mounted flush to a hard wall. The microphones rely on direct sound and reflections from the mounting surface. A backboard provides a useful reflective surface when the wall is uneven, covered with absorptive material or otherwise prevents flush mounting. Don’t mount the bar directly on soft fabric or acoustic panels.

Adaptive Voice Lift provides subtle voice reinforcement, typically around 6 dB, so talkers sound closer and are easier to hear without sounding obviously amplified. One-way voice lift can be used when a room has a predictable presenter area, and full-room voice lift should be used to lift voices from anywhere. Adaptive Voice Amplification supports dedicated microphone use cases and provides stronger reinforcement, approximately 20 dB, when a presenter or room requires a more traditional amplified experience.

Camera switching automatically changes the camera views in a room based on who is speaking. Use the Nureva App or Nureva Console to configure your supported cameras and create camera zones on the coverage map. Enter the correct room dimensions first. Then walk through the room and speak from various positions to confirm the sound location data is showing in the right places and that the expected camera view is selected. Follow the integration-specific setup guide for network and firmware requirements.

Echo or uneven audio can come from room reflections, high background noise, incorrect system placement or audio processing settings that don’t match the room. Start with a test call. Check placement and room acoustics before changing settings. If voices cut out, reduce the echo reduction or noise reduction. If remote participants hear their own voices or steady background noise, increase the related setting by one step and retest.

First, confirm that the Nureva system is selected as the conferencing application’s microphone and run a test call. Check that microphone paths aren’t blocked and that the bar or pods are away from fan noise. Review room reverberation and background noise. If the problem continues, adjust the microphone gain or audio processing controls for the installed system. Then retest.

Use the Nureva App to set up, configure and manage a Nureva audio system locally. Use Nureva Console to monitor and manage enrolled systems remotely at scale. The Nureva App is also useful when internet access or network restrictions prevent the use of Nureva Console.

The HDL310 and HDL410 systems can connect to the Nureva App through the mobile app, a web browser, direct Ethernet connection or a USB connection to a computer. HDX systems can connect through the mobile app, a web browser or a USB connection to a computer. Enter the device IP address and then use the enrollment code or device password when prompted.

Use a direct Ethernet connection when you can’t reach the Nureva App over the local network or don’t know the device IP address. Connect the system’s network port directly to your computer, tablet or phone. In a supported browser (Chrome™ and Safari®), enter 169.254.254.254 and then enter the enrollment code or device password. A USB-to-Ethernet adapter may be required.

Update the system through the Nureva App or Nureva Console when an update notification appears. The device won’t be available for calls during the update, so schedule the update for when the room is free. Don’t turn off, unplug or disconnect the system until the update is complete. For initial HDX setup, use a USB connection and a computer with internet access.

To find the IP address of a Nureva audio system enrolled in Nureva Console, open the room, select the audio system and expand Hardware and network. If you need the system to use the same IP address consistently, either assign a static IP address in Settings > Network using values provided by your network administrator or create a DHCP reservation on the network. DHCP reservations are recommended when integrations or workflows require a predictable IP address.

Yes, Nureva audio systems can operate without internet access for audio conferencing, but cloud-based services, device updates and remote management features require an internet connection.

Use the acoustic check score to assess room suitability. A score of 75 or higher is ideal, 25 to 74 is supported and below 25 is challenging. The recommended RT60 range is 0.2 to 0.6 seconds, and the recommended background-noise range is 0 to 52 dBC. Review the individual measurements before selecting the installation location. If a challenging room is identified, you can work with a local specialist to determine the level of acoustic treatments needed. Acoustic treatment can enhance speech intelligibility in a room and improve the remote audio experience.
