6.6. Product compliance

This product complies with all relevant European Union Directives and the following relevant product safety standards:

EN 55032:2015 + AC:2017 + A11:2020 (Electromagnetic compatibility of multimedia equipment - Emission Requirements (CISPR 32:2015 + COR1:2016))

EN 55035:2017 + AC:2020 (Electromagnetic compatibility of multimedia equipment - Immunity requirements (CISPR 35:2016, modified))

While using the Microphone, magnetic fields generated by other electronic devices may induce non-destructive noise on the Microphone capsule. The distortion introduced by electromagnetic fields is not damaging to the Microphone or the accuracy of the intended acoustic measurement: Product performance deviations and performance thresholds are accounted for when used with the SoundID Reference software ("Sonarworks-native use").

7. SoundID Reference Microphone Profile

7.1. Microphone Profile and Profile ID

The frequency response of each Microphone unit has been individually measured, and a unique Microphone Profile is provided containing the measured frequency response data. The individual Microphone Profile is associated with a Profile ID, printed directly on each Microphone unit, as shown in Figure 5 below:

Figure 5: Microphone Profile ID (example)

Each Product unit includes a unique Microphone Profile, associated with three separate profiles to be used for various angle measurements:


30° profile

90° profile

For Sonarworks-native use, the SoundID Reference Measure application ("Measure app") employs the 30° profile for 2.0 stereo configuration measurements, while 2.1-9.1.6 multichannel configuration measurements employ both 30° and 90° profiles. 

7.2. Sonarworks-native use

To achieve optimal results with Sonarworks-native use of the Product, the Microphone Profile must be employed during the measurement process:


Click on the 'SoundID Reference microphone' option during the "Hardware Setup" stage in the Measure app.


Enter the Microphone Profile ID and click 'Next' to load the Microphone Profile.

Once the Microphone Profile is loaded in the Measure app (see example below), the correct angle profile(s) are applied automatically, based on the configuration selected during a previous step in the Measure app.

7.3. Microphone Profile downloads

For offline use, third-party software/hardware use, or general backup purposes (in accordance with Section 4), the Microphone Profile files can be downloaded in a ZIP archive from the Sonarworks website:


Go to the Downloads page on the Sonarworks website:


Navigate to the "Measurement microphone profile downloads" section.


Enter the Microphone Profile ID and click on the 'Download profile' button.


Extract the downloaded ZIP archive to access the Microphone Profile files.

The download will contain two files in the Sonarworks-native SWMIC file format and three files in TXT file format for third-party use:

30° Microphone Profile in SWMIC file format 

90° Microphone Profile in SWMIC file format 

 Microphone Profile in TXT file format 

30° Microphone Profile in TXT file format 

90° Microphone Profile in TXT file format 

7.4. Offline and third-party use

For Sonarworks-native offline use, the Measure app allows for the Microphone Profile to be loaded manually, in case there is no internet access on the computer ("Machine") used for the measurements at the given moment:


Download and extract the Microphone Profile files as described in Section 7.3 above 


Transfer the files to the needed Machine using a USB flash drive, or another offline transfer method 


Click on the 'Different measurement microphone' option during the "Hardware Setup" stage in the Measure app, and click 'Next' to proceed


Click on 'Browse' and select the Microphone Profile TXT file


For 2.0 stereo configuration measurements, load the 30° TXT file.


For 2.1-9.1.6 multichannel configuration measurements, load the 90° TXT file.

Note: For Sonarworks-native use, 2.1-9.1.6 multichannel measurements require both 30° and 90° profiles to be used, which can only be done by entering the Profile ID in the Measure app as described in Section 7.2. Loading only the 90° TXT file manually will result in reduced measurement accuracy.

For third-party use, the Microphone Profile files can be downloaded and employed in TXT file format as described in Section 7.3.

Note: Sonarworks is not responsible for any compatibility-related issues assiocated with third-party use of the Microphone Profile. It is the user's responsibility to resolve any such issues according to the third-party software/hardware legal guidelines, documentation, and other sources of information.

Do not use damaged XLR cables. Unsecured connections can cause electric shock or fire.

Do not pull the cable excessively when disconnecting it from the device. Doing so may cause electric shock or fire.

Do not attempt to disassemble the chassis of the device. If parts of the chassis are loose, contact the manufacturer immediately.

Only use accessories that are compatible with the product. Using incompatible accessories may result in injury and/or property damage.

Do not drop or cause excessive impact to the device. This may damage your device or its internal components, cause the device to malfunction, or shorten its lifespan. This may also cause overheating, combustion, fire, or other hazards.

Never place the device on or in heating devices, such as microwave ovens, stoves, or radiators. The device may explode when overheated.

Avoid exposing the device to high external pressure. This can lead to an internal short circuit and overheating.

Avoid exposing the device to very cold or scorching temperatures. Extreme temperatures can damage the device, and reduce its life span.

Do not store the device near or in heaters, microwaves, hot cooking equipment, or high-pressure containers. Your device may overheat and cause a fire.

Do not use or store your device in areas with high concentrations of dust or airborne materials. Dust or foreign materials can cause your device to malfunction and may result in fire or electric shock.

Do not expose the device to heavy smoke or fumes. Doing so may damage the electrical components of the device or cause it to malfunction.

If you use a hearing aid, contact the manufacturer for information about radio interference. The radio frequency emitted by your device may interfere with some hearing aids. Before using your device, contact the manufacturer to determine whether or not your hearing aid will be affected by radio frequencies emitted by the device.

Do not store or carry flammable liquids, gases, or explosive materials in the same compartment as the device, its parts, or accessories.
