How to calibrate the Dual HDL300 system

The Nureva^® Dual HDL300 system has two types of calibration processes — automatic calibration (autocalibration) and manual calibration. Conveniently for users, the Dual HDL300 system routinely calibrates itself.

Autocalibration

Autocalibration is a continuous process and occurs while the Dual HDL300 system is switched on. No user action is required to start or maintain the autocalibration process. It usually takes a few minutes for the system to gather sufficient calibration data and it continues to fine-tune to the room setup over time. This process does not affect functionality and the system is usable during autocalibration.

The Dual HDL300 system autocalibrates to accommodate changes in the room such as the number of people or the configuration of furniture.

Manual calibration

Calibration of the Dual HDL300 system is completed in approximately 20 seconds. This process automatically starts when the device is first unboxed and switched on. Additionally, calibration may be initiated manually through a remote control button sequence or by using Nureva Console.

We recommend installing the Dual HDL300 system before switching it on for the first time. If the system is switched on pre-installation, it will still require calibration after being installed to ensure optimal audio quality.

Calibration can be manually started at any time, but this is usually done when the room configuration has changed significantly. Do not perform a calibration sequence and then reposition the Dual HDL300 system or furniture. Make sure there are no audible sound sources in the room other than normal ambient noise (e.g., no music playing, no people talking).

It’s possible to start a calibration sequence during a call. However, both parties will not be able to hear each other while calibration is taking place. The microphones and speakers will be temporarily disconnected and the call will resume after calibration is complete.

Note: During manual calibration the system generates pink noise (sounds like static) and the status indicator lights on the microphone and speaker bar will alternate between solid red and solid blue. After 15 to 20 seconds, the pink noise stops and the status indicator lights return to a normal state, signalling that the calibration sequence is complete.

Calibrate through the Nureva App

The following steps are required to perform calibration through Nureva Console:

1. Open the Nureva App.

2. Open the Settings menu.

3. Select Audio processing.

4. Navigate to Calibrate and click Start.

When the calibration signal stops and the status indicator lights return to a normal state, calibration is complete.

Calibrate through Nureva Console

The following steps are required to perform calibration through Nureva Console:

1. Open Nureva Console.

2. Select the Nureva audio system to be calibrated.

3. Scroll down to Settings and open the menu.

4. Select Audio processing.

5. Navigate to Calibrate and click Start.

When the calibration signal stops and the status indicator lights return to a normal state, calibration is complete.

Calibrate using the remote control

Below are the steps for initializing manual calibration through the remote control.

1. Press the F4 button on the remote control five times in quick succession.

   • A single blue light will start flashing on the integrated microphone and speaker bars.

2. Press the Mute button on the remote control and the Dual HDL300 system will enter calibration mode.

   • The status indicator lights will alternate between solid red and solid blue.

When the calibration signal stops and the status indicator lights return to a normal state, calibration is complete.
