Nureva HDX Series - Pre-Installation Considerations

IMPORTANT NOTE:

This is a summary of the full HDX User Guide, provided by Nureva. We strongly recommend that you read this in full prior to purchase / installation of any HDX system.

This overview is provided by Ascentae as a basic guide of what to look for to ensure a smooth installation of HDX systems in a typical deployment. As such, advanced functionality such as integration with 3^rd party subwoofers, Adaptive Voice Amplification and Adaptive Voice Lift are not included in this overview. Additional guidance for these scenarios can be found in the full HDX User Guide.

For the purposes of this overview, all rooms are considered to be regular shape. For details of options in irregular shaped rooms, refer to the full guide.

As this guide is provided as a pre-installation reference, it does not cover the installation process. Details of installation best practice can be found in the full guide or on the Nureva support site – support.nureva.com.

HDX Overview

The Nureva HDX series is a mutli-component audio system which is suitable in spaces up to 223m². It consists of 3 elements – Providing full range distributed audio, adaptive voice lift, adaptive voice amplification, full room microphone coverage, assisted listening via Auracast and full connectivity to UC platforms (Teams, Zoom etc).

The HDX series offers 5 modular configurations, consisting of 3 components.

System Hub

All in one system eliminating need for separate DSP’s, amps and Bluetooth transmitters

- AV-over-IP for single cable installation - Bluetooth audio streaming - Auracast broadcast audio - Intelligent compute features including camera tracking, controller integration & device management - Passive cooling for quiet operation Sleep mode for energy conservation
Audio Bars Speakers / microphones combined in single, easy to install unit to support distributed audio. - Full range distributed audio and full room microphone coverage - 2-way speaker system with tweeter & dual woofer - 2 dimensional microphone array - Single Ethernet connection to hub Flexible horizontal or vertical installation - Flexible horizontal or vertical installation
Microphone Pod (option) Spports Microphone Mist for improved full room coverage - 2 dimensional microphone array - Single Ethernet connection to hub - Flexible installation on wall or ceiling

HDX Configurations

Prior to purchasing a HDX system consider the following

- Room Dimensions – get accurate measurements of room

- Active locations – note where people speak, seating & presenter areas and if there is a ‘front of room’

- Room environment – consider which physical locations are best for HDX component placement

- Room acoustics – assess reverberation & background noise to determine best placement for HDX components.

Coverage for each HDX configuration is based on the length of the longest wall. For rooms with a more complex geometry, consider a larger configuration or add microphone pods to provide best coverage.

- 2 HDX Audio bars are suitable for rooms up to 91.m in length

- 4 HDX Audio bars are suitable for rooms up to 18.3m in length

- Microphone pods can be added to extend pickup coverage and support Adaptive Voice Lift

HDX Placement Guidelines

In order to provide best audio coverage in any given space, follow these principles:

1. Maintain a clear line of sight between audio bars & microphone pods. The system performs best when they have a clear, unobstructed view of each other and the room.

2. Avoid obstacles. Avoid placing components behind pillars, inside alcoves and in recessed areas.

3. Stay clear of noise sources. Position components away from HVAC vents, fans and other equipment that produces continuous background noise.

Audio Bar Placement

Audio bars can be mounted horizontally or vertically on the wall using the supplied mounting bracket, or on VESA standard mounting solutions (display mounts, floor stands, mobile carts etc).

Firstly, consider whether the space has a defined ‘front of room’ as this is the natural focal point of a meeting or presentation where audience attention is focused.

2 Audio Bar Solution

Ideally, for rooms with a defined front position, place 2 audio bars along this wall, evenly distributed (¼ and ¾ points on along the wall) to provide balanced audio for both presenters and audience.

For spaces without a defined ‘front of room’, the optimal positioning should be on the same long wall.

For more details, refer to HDX User Guide - https://www.nureva.com/user-guide/hdx/placement

4 Audio Bar Solution

Use a balanced, symmetrical layout to provide consistent coverage across the room.

For spaces with a defined ‘front of room’, there are multiple options for positioning.

For spaces without a ‘front of room’ the bars should be positioned evening along the long walls to provide consistent coverage.

Audio Bar Orientation

HDX Audio bars can be mounted vertically or horizontally.

- Vertical orientation (default) – microphones are positioned in the upper half of the bar, to provide optimal localisation and clarity

- Horizontal orientation – the speaker drivers need to be positioned towards the outer edges of the room for even sound distribution. This works best when working around windows and other obstacles.

Guideline	Measurement	Why this helps
Suggested height from floor	91 – 366cm	Audio bars being placed at or above head level will help direct sound towards listeners and improve microphone pickup. Maintain minimum clearance of 8cm above the audio bars for wall mount installation and service
Minimum distance from adjacent wall or corner	30cm	Avoide placing audio bars on walls close to corners to reduce echo. If corner placement is required, angle the audio bars to face into the room using a VESA standard mounting solution (not provided).
Minimum spacing between audio bars	152cm	Adequate space between the audio bars helps prevent them playing directly into other components, reducing echo and supporting consistent performance

Microphone Pod Placement

One or two microphone pods may be mounted on the ceiling, wall or VESA standard mounts, depending on room layout, furniture arrangement and location of primary talker.

The below layouts demonstrate different placement examples but microphone placement is flexible depending on the use case.

Examples – 1 microphone pod

Examples – 2 microphones pods

Microphone Pod installation

Installation is very flexible. The supplied bracket supports any orientation is supported except for upside down on a wall.

Microphone Pod Mounting Guidelines

Guideline

Measurement

Why this helps

Typical ceiling-mounted height

244 to366cm

The coverage and sensitivity of the microphones are balanced, helping capture voices clearly

Minimum wall mount height

91cm

The placement of microphone pods above seated height helps maintain clear pickup.

Minimum spacing from audio bars

152cm

Adequate spacing between microphone pods and audio bars ensures speakers and microphones are not facing directly towards each other, reducing echo and supporting features such as Adaptive Voice Amplification and Adaptive Voice Lift

System Hub Positioning

The HDX system hub can be placed on a table, shelf or rack, or wall mounted. Regardless of placement, ensure adequate ventilation an an unobstructed Bluetooth connection.

For optimal placement consider

- Side ventilation: allow at least 56mm of clearance

- Top ventilation: allow at least 86mm of clearance above

- Heat considerations: do not install the system hub near other devices that generate heat. Ambient temperature must remain below 40°C

- Bluetooth antenna: ensure it is upright for best signal strength. Antenna extender are not recommended.

- Password and enrolment code are located on the base of the system hub. Make a note of these prior to final installation of the hub as they will be needed to enrol system into Console.
