Setting up a wireless headset or earset with the HDL410 system

Most wireless headset and earset microphones with an XLR-out connection are supported for use with the Nureva^® HDL410 system and Voice Amplification Mode.

Before starting

1. Confirm the HDL410 system has the latest firmware.

   • Firmware version 1.1.209937 is the minimum required to enable voice amplification.

2. Enroll the HDL410 system into Nureva Console cloud to enable remote management.

3. Source a balanced XLR to unbalanced 3.5 mm TRS adapter cable (required).

   • The connect module for the HDL410 system only supports mono and unbalanced audio inputs.

   • This cable is purchased separately. See your audiovisual reseller to purchase this cable.

Step 1: Connect the system

Set up the HDL410 system

1. Connect the Ethernet cables (provided) to the RJ45-1 and RJ45-2 ports on the connect module.

2. Run the Ethernet cables to the RJ45 ports on the back of each microphone and speaker bar.

3. Connect a CAT5e Ethernet cable (not supplied) to the network port on the back of the connect module.

4. Plug the CAT5e Ethernet cable into an available network port (router, modem, wall jack).

5. Connect the provided power supply to the connect module and plug it into an outlet or a power bar.

Connect the wireless headset or earset system

Using the balanced XLR to unbalanced 3.5 mm TRS adapter cable:

1. Connect the cable to the XLR port on the back of the headset receiver.

2. Connect the cable to the Aux-in port on the back of the connect module.

3. Set the microphone receiver to Line level output (if this feature is available).

4. Connect the microphone receiver to the power source using the power cable and power supply.

Pair the transmitter to the receiver

Ensure the headset is disconnected from the transmitter at this time.

1. Turn on the transmitter.

2. Set the group and channel according to the microphone instructions.

3. Make sure other wireless microphones nearby are not using the same group and channel.

Step 2: Adjust volume output on computer

The volume setting on the computer affects the amplification level. Start with the volume set at a level normally used in the room. This can be adjusted at any time.

Step 3: Adjust settings in Nureva Console

The instructions below are completed using Nureva Console cloud. Voice Amplification Mode is not available with the Nureva Console desktop client.

1. Go to the sign-in page for Nureva Console and log in.

2. Select the HDL410 system that was connected in Step 1.

Adjust speaker settings

1. Go to Device settings and open Speakers.

2. Select Custom to adjust the Bass and Treble settings to 50.

   • If there is no distortion during testing, the bass setting can be increased to meet individual preferences.

   • Reducing the bass setting can help reduce feedback and audio artifacts.

Dynamic boost

HDL410 systems with firmware 1.9 (or later) installed offer different presets for treble and bass than systems using firmware 1.8 (or earlier). Included in these presets is dynamic boost. When using Voice Amplification Mode along with dynamic boost, careful consideration is required when tuning the wireless microphone.

Learn more about using dynamic boost and Voice Amplification Mode.

Enable Voice Amplification Mode

1. Go to Device settings and open Voice Amplification Mode.

2. Enable Voice Amplification Mode by sliding the toggle to the right.

3. Click Apply at the top of the device settings dashboard.

Microphone ducking

Microphone ducking is a setting that improves the experience for remote participants by preventing dual audio signals in situations when Voice Amplification Mode is used. When activated, microphone pickup by the HDL410 is muted and only the headset microphone picks up the presenter’s voice. Whenever the presenter stops speaking, the Nureva device’s microphones provide full-room pickup. HDL410 systems with firmware 1.9 (or later) installed offer this feature.

Adjust the aux-in level

• Switch the Aux in setting to Line level to match the receiver.

Adjust the amplification level

1. Start with the Amplification level at Medium (Default).

2. Select the amplification level that provides the best quality voice amplification.

Step 4: Test the amplification

Test the system

1. Connect the headset or earset to the transmitter.

2. Stand approximately 1 to 2 meters in front of the microphone and speaker bar.

3. Have someone stand at different places around the room while talking to test the amplification level.

4. If a UC&C client (e.g., Microsoft^® Teams, Zoom) is used, test the amplification setup with a remote person in an audio or video conference.

Adjust amplification

1. Increase or decrease the master volume output from the computer to the correct volume level for the room.

2. Using the gain control or dB settings on the transmitter, fine-tune the wireless microphone to ensure the audio output is sufficient.

3. If there is feedback or squelch, lower the gain or dB setting for the microphone transmitter and ensure Aux in is set to Line level.
