Setting up a wireless headset or earset with the HDL300 system

Most wireless headset and earset microphones with an XLR-out connection are supported for use with the Nureva^® HDL300 system and Voice Amplification Mode.

Before starting

1. Ensure the Nureva Console client application is up to date.

   • Version 1.3.171812 is the minimum required to enable voice amplification.

2. Confirm the HDL300 system has the latest firmware.

   • Firmware version 2.4.67 is the minimum required to enable voice amplification.

3. Enroll the HDL300 system into Nureva Console cloud to enable remote management.

   • The connect module for the HDL300 system only supports mono and unbalanced audio inputs.

   • This cable is purchased separately.

   • See your audiovisual reseller to purchase this cable.

1. Connect the USB cable (provided) to the USB-B port on the connect module.

2. Run the cable to a computer, connecting to a USB-A port.

3. Connect the Power over Ethernet (PoE) cable (provided) to the RJ45-1 port on the connect module.

4. Run the PoE cable to the RJ45 port on the back of the microphone and speaker bar.

5. Connect the power supply to the connect module and plug it into a power source.

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 currently available in Nureva Console client.

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

2. Select the HDL300 system that was connected in Step 1.

Adjust speaker settings

1. Go to Device settings and open Speakers.

2. Select Custom and set 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.

Disable sleep mode

1. Go to Device settings and open Auxiliary ports.

2. Ensure that Sleep mode is set to OFF by sliding the toggle to the left.

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.

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.
