FAQs

No, that is not possible. Instead connect all devices via Ethernet.

We occasionally receive questions about the surface temperature of the KLANG:1 and KLANG:1pro.

The housing of both products is intentionally designed to act as a heat sink and is an integral part of the cooling system. As a result, the enclosure may feel warm or even hot to the touch during normal operation, especially after extended use.

This behavior is expected and is fully within the specified operating limits of the product. Both the KLANG:1 and KLANG:1pro have been thoroughly tested and validated under high-temperature operating conditions to ensure reliable performance and long-term stability.

No additional cooling equipment is required when the unit is used within its specified environmental conditions and with adequate ventilation around the device.

The operating temperature of the enclosure does not indicate a fault and will not cause the unit to behave erratically. If the product is operated according to the instructions provided in the user documentation, it will continue to function as designed.We occasionally receive questions about the surface temperature of the KLANG:1 and KLANG:1pro.

Yes, that is possible.

KLANG:app, all KLANG processors and KLANG:kontroller exclusively communicate with each other via OpenSoundControl (OSC) messages. Find all details about the OSC messages in the OSC Reference Guide.

KLANG:app can further be connected to MIDI MCU and MIDI for Allen & Heath consoles.

The KLANG:kontroller can be powered either via PoE (Power over Ethernet) over its Neutrik etherCON connection, or via the included DC power supply. It uses standard IEEE 802.3af PoE (Class 0), so plan for up to 15 W per port on your network switch — the actual power draw in operation is somewhat lower. When compliant PoE is available, no separate power supply is needed.

The latest Windows OS update in the beginning of 2026 has introduced MIDI 2.o and there are several reported issues with MIDI devices disappearing. This is not limited to KLANG:app at all. Details and some troubleshooting steps can be found here. 

In order to create an immersive mix you always need a KLANG processor. KLANG:kontroller can control a mix on that processor and will connect to it via Dante.

The CONFIG menu on :kontroller can be deactivated / locked to prevent accidental changes of critical :kontroller settings. This setting can be changed via KLANG:app (Admin mode) > login to :kontroller > CONFIG > INFO > Set Menu > Config Menu

A long button press (>3sec) on AMB/AUX activates CONFIG menu access if one of the following criteria is met:

• AMB/AUX menu is currently shown
• Within the first 10sec after :kontroller is booted
• :kontroller is currently not connected to any mix

It’s an automatic IP address in the range 169.254.x.y/16, assigned when no DHCP server is available. Devices can still communicate with each other on the same subnet.

If your KLANG system can’t find a network with a DHCP server (the box that normally hands out IP addresses, e.g. a WiFi router), it will just give itself a number automatically so everything can still talk to each other. These self-assigned numbers always start with 169.254… and are called link-local addresses (sometimes also called “zeroconf”). It’s nothing to worry about — your devices will still connect and work together. For bigger setups, engineers might introduce a DHCP server or may switch to fixed IPs, but for a quick jam or smaller shows, link-local works fine out of the box.

Officially supported operating systems for KLANG:app are Windows, Mac Os, iOS and Android.

• Windows 7, 10 and 11 in both 32-bit and 64-bit
• Mac OS X 10.13–13.x
• iOS – latest two versions are tested and supported.
• Android – there are various different versions, which cannot all be tested in combination with different hardware of tablets and smartphones.

Please note, that OxygenOS (OnePlus) might not work properly, this is officially not supported; neither are Windows Phones.

Step 1: Enable Dante Follow, either on KLANG:kontroller directly or via KLANG:app.

Step 2: Login to your KLANG processor with KLANG:app that the KLANG:kontroller should connect to and search for the Dante Transmitter Name (automatically detected on KLANG:vokal with KLANTE; or manually set on other KLANG processors with built-in Dante).

See here for more details: Configure Dante Follow

KLANG uses UTC timestamps throughout to support devices with multiple time zone settings simultaneously. This explains why you see a constant time offset.

See details about UTC and on how to determine the offset here: https://en.wikipedia.org/wiki/Coordinated_Universal_Time

You only need a WiFi router if you want to connect KLANG:app on smartphones or tablets, e.g. for personal mixing or for a monitor engineer when working on the stage.

A hardwired ethernet connection is always the best choice for critical communication links, e.g. when running the DiGiCo console integration. We recommend to use a hardwired ethernet connect whenever possible, especially for laptops or computers with an ethernet port.

There are two different frequency bands for WiFi – 2.4 GHz and 5 GHz. We recommend to use dual band WiFi routers or Access Points. The 2.4 GHz band might get very busy or noisy when several mobile devices are around. The 5 GHz band tends to be the better choice. In many systems it is possible to define unique SSID to the 2.4 and 5 GHz bands, so it is easy to see on a mobile device on which band you are working on. Modern mesh routers are more intelligent and tend to provide the best performance in all situations.

In general, managed switches with deactivated EEE are preferable and work best with Dante networks.

Visit our Quick start guide on Network switches to find the features you need.

Newer Mac computers might ship with a fast 10G network adaptor. This adaptor sometimes runs into communication issues if the connected device (e.g. a network switch) does not support 10G. In that case, a significant percentage (e.g. up to 50%) of the network traffic might be dropped. But as it still works from time to time, this problem is hard to troubleshoot. Unfortunately, this issue has not been addressed properly by the manufacturer of these computers, yet.

Solution: Use a USB Gigabit network interface.

Dante Follow is a feature on the KLANG:kontroller that automatically connects its Dante interface to the appropriate mix on a KLANG processor.

When enabled, the :kontroller’s control section identifies the processor it’s connected to and subscribes to a Dante transmitter with the same device name, updating the subscription whenever you switch mixes, so you don’t need to manually route audio through Dante Controller.

Follow these steps to setup Dante Follow.

Yes, you can configure Custom OSC Receive Ports in KLANG:app:

Go to KLANG:app (5.6.7+ required) > CONFIG > INFO > Set Menu > Custom OSC Receive Port > and enter an additional port KLANG:app should listen on for incoming OSC messages, e.g. 9112.

The KLANG:app > CONFIG > INFO > Set Menu gives access to important configuration options for your local KLANG:app instance and the connected device, e.g. KLANG processor, another KLANG:app or a KLANG:kontroller.

See full documentation

Yes, that is possible. Go to KLANG:app > CONFIG > INFO > Set Menu > Musician Mix Lock

KLANG:app communicates OSC UDP network messages with the KLANG processor. Normal mixing operation including audio meters should stay below an average of 0.5 MBit/s.

The order of groups can also be changed. Use the move up and move down icon to move a group and all its member channels one position up or down. Follow this link for more details.

KLANG:app containers are tested before uploaded to the download section of this website. CleanMyMac sometimes erroneously detects KLANG:app as BirdMiner malware. We can assure that this is a false positive and our developers have reached out to the clean my mac developers to resolve this warning on their end.

There is no need for additional tools such as CleanMyMac and they are known to cause performance issue. Please ignore this warning.

This is a known issue with webroot.

Solution: get in touch with your system admin to disable webroot.

If any channel in a mix is on solo, a red icon with “S” for solo appears  just above the FADERS menu icon.

If any channel in the mix is muted a yellow or orange icon with “M” appears.

It is possible to generally disable demo mode. This is particularly useful to prevent the demo mode button to appear in case KLANG:apps are disconnected from KLANG hardware network. Users might click the button accidentally and not notice that they are now mixing the built-in demo song instead of their own in-ear mix.

To disable, go to ADMIN mode and log in to a KLANG:fabrik/KLANG:vier mix or the built in demo mode. Then, navigate to CONFIG > INFO > Set (button) > Advanced > DON’T show demo mode. Fully restart KLANG:app. Now the demo mode will not be listed in the CONNECT screen anymore.

To enable again, go to ADMIN mode and navigate to CONFIG > CONNECT. Press and hold the refresh ICON (circular arrow at the bottom) for 4 seconds.

On iOS and Android, multi-touch is inherently supported. On Windows, KLANG:app can be used with a multi-touch display, i.e. several faders and icons can be moved in parallel. However, on Mac OS X, multi-touch displays are not supported as such. Hence, only a single fader or a single icon can be moved one after another.

– We are currently working on a solution for this and work around the barriers of Mac OS X –

The Digital Rights Management (DRM) is sometimes causing an issue on Amazon Tablets. The tablet needs to be connected to the internet from time to time to renew this license. DRM might be deactivated in future KLANG:app releases for the Amazon AppStore. To workaround, please connect the tablet to the internet at least once every month.

Depending on your input channel requirements and the number of mixes required, more than one KLANG device can be connected to the same control network. Input channels arriving on KLANG:fabrik e.g. via MADI, can be routed to other KLANG:fabrik and KLANG:vier (48kHz only). Dante input channels can be routed to as many receiving devices as needed. Depending on the network load Dante Multicast flows have to be used and managed, switches with proper IGMP snooping and QoS configuration should be used.

Most KLANG immersive processors can be configured to work in a cascade of units.

There is no limit other than your network limitation as to how many KLANG:fabrik and KLANG:vier can be added to your network. KLANG:app will show each KLANG device available on your network.

Our products are designed and tested to be used with at least one :app or :kontroller per mix, plus two :apps for engineers. In most cases, it is possible to use even more apps; there is no fixed limit.

To back up all internal settings, presets, and log files from every KLANG device and connected KLANG:app instance:

1. Open KLANG:app

2. Go to CONFIG > INFO > Collect All Logs

3. Wait until the button turns green

4. Click Save Logs as ZIP

5. Send the ZIP file to KLANG support if needed

This creates a full backup and troubleshooting package for your entire system.

Yes. KLANG:app has a built in offline editor. Follow this link for more details.

It is now possible to enter a KOS Login Password. Users need to know this password to connect to the processor in Show or Admin mode. Follow this link for more details.

Yes, channels can be hidden in KLANG:app running musician or personal mode and on :kontrollers, and therefore be protected from changes. Follow this link for more details.

The first two KLANG processors, namely :fabrik and :vier used the same hardware platform. These are the first generation (1st gen) KLANG processors and they both use the same KOS update files.

All processors developed after – :vokal, :vokal+, :konductor, DMI-KLANG – use a different hardware platform and are therefore called second generation (2nd gen) KLANG processors. The KLANG:kontroller is based on the same platform and uses the exact same KOS update files. The KOS firmware files for the 2nd generation processors are the same.

KLANG:quelle XDM uses a completely different firmware and hence update files.

KLANG:app has a built-in update system for Over-the-Air updates. It automatically downloads the correct firmware files from the internet and installs it on the device.

Both generations are compatible with the same KLANG:app and Show files can be exchanged between 1st and 2nd generation processors as well.

Multiple KLANG immersive processors can be linked in KLANG:app to act as a single unit. This cascade of units will be defined by the unit name followed by an alphabetically sorted index in braces ().

While it is possible to cascade different types of processors, this feature is intended to be used with the same type of processor, e.g. cascade two :vokal devices.

KLANG products are designed to be used for long periods of time and our philosophy will always be to try our best to offer support for as long as it is needed. However, this might become limited for various reasons, for example where we are depending on third party component suppliers, soft- and hardware developers etc. Our legacy products KLANG:fabrik (introduced in 2014), KLANG:vier and KLANG:quelle 19” are still receiving updates today, following this philosophy.

KLANG does not rely on rigidly fixed software update cycles (e.g. once or twice a year). Instead, we aim to constantly maintain and improve the user experience, especially by releasing KLANG:app improvements to react to changes in smartphone or computer operating system updates as soon as possible.

Find the latest software updates here.

Presets are by default stored inside the immersive processor hardware and can be recalled directly via KLANG:app. In order to backup presets or transfer them from one KLANG device to another, simply connect with KLANG:app go to the CONFIG > PRESET page, select a preset from the dropdown and click TRANSFER.

Presets are interchangeable between different immersive processors, e.g. between KLANG:fabrik and KLANG:konductor.

More info on Preset…

All KLANG immersive processors allow for CUEing into all available mixes. This is particularly helpful for monitor engineers who constantly need to switch between mixes. Details on the CUE functionality can be found here.

Find information on immersive in-ear mixing tips here.

Follow this step-by-step guide for your product here…

KLANG:vier can receive (Dante and ADAT comp.) and transmit (Dante) audio with 44.1 and 48kHz.

KLANG:fabrik can receive and transmit digitial audio (Dante, MADI, ADAT comp.) with single speed sampling rates 44.1/48kHz and double speed sampling rates 88.2/96kHz. At double speed, ADAT comp. inputs and outputs use SMUX format. MADI input can receive 28/32channel with high frame rate and SMUX. Transmit is always high frame rate with 32 channels.

KLANG:quelle can receive Dante audio with 44.1/48kHz, 88.2/96kHz and 176.4/192kHz.

KLANG:vokal, DMI-KLANG, :kontroller and :konductor can work with 48kHz and 96kHz and offer the exact same channel count / mix count with both sample rates.

A mix (or :output as labelled on the back of e.g. KLANG:fabrik) always refers to stereo pair of output channels. In order for the 3D processing to work, the connection between our immersive KLANG in-ear mixing processor and the in-ears / headphones has to be stereo as well.

The KLANG console integration is available on the following DiGiCo consoles

• SD series
• Quantum series

It depends. Details can be found here: KLANG DiGiCo Console Link

1st generation KLANG processors :fabrik and :vier always require a computer running KLANG:app for the console integration.

2nd generation KLANG processors (:konductor, :vokal, DMI-KLANG) can run a standalone console integration (KOS 5.5 required).

If a cascade of KLANG processors is used, this also always requires a computer running KLANG:app for the console integration.

Yes, you can activate Dark mode/:kontroller blackout which turns all LEDs and Displays (except for the last one) off. This is particularly useful for theatres when the stage should be as dark as possible. With a push on any rotary button, the dark mode can be exited. [KKA-120]

In order to revert all :kontroller back to normal operation, use “Switch lights back on”. Follow this link for more details.

No. KLANG incorporates binaural technology and processes the sound inside a KLANG processor to work with your own pair of standard stereo headphones or in-ears. In fact, it is not important whether your headphones are open or closed, electrostatic or dynamic or use balanced armature drivers as most in-ears do. You can use universal fit in-ears or custom molded in-ears. Just make sure that the polarity is correct and the left and right signals go to the correct ears.

It’s both!

The KLANG system is designed to be very easy to use, especially if you don’t have years of experience in mixing monitors. The 3D in-ear mixing functionality enables musicians to get a very transparent and natural in-ear / headphone mix in a very short time.

At the same time, our products and especially KLANG:app offer all features that experienced sound or monitor engineers expect when working with a mixing tool for the live or studio market. Especially features like CUE mixing for musicians is a feature you want to use at mixing monitors constantly.

KLANG:app and KLANG:kontroller offer customizable DCA groups for an improved mixing workflow e.g. during a show. By default, the volume of all other groups is decreased when the volume of one group is increased. This helps to keep the sound pressure level approximately the same and prevent the mix to get louder.

However, if you want to deactivate relative DCA group mixing, go to KLANG:app > FADERS (2nd page / group) and click on the relative group mixing icon:

In order to change the behavior for another KLANG:app or KLANG:kontroller remotely, go to CONFIG > INFO > Set Menu > Disable KLANG:app Relative Group Mixing. Please note, that for this, your KLANG:app needs to be in Admin mode. 

:kontroller always supports all groups of a mix. The maximum number of groups per KLANG mix is 16. By pushing GROUPS on :kontroller, the first 8 groups are shown, and by pushing GROUPS for a second time, the last 8 groups are shown.

:kontroller supports 3 banks of 8 channels each, so the first 8 channels of a KLANG mix are available. It is important to sort the most important channels that should be controlled to the first 24 in the KLANG mix. However, the groups can always control the channels 25+. It is also possible to hide a channel from the :kontroller, without the need to re-sort the channels. Hidden channels are still audible in the mix but cannot be individually tweaked. However, if the group is changed in level, these hidden channels will follow.

Close your eyes and listen with your ears only. You will realise that you can immediately tell where a sound is coming from. The sound travels from the source to our ears and several things happen before it it finally hits our ear drums:

The first effect is most obvious: The speed of sound is limited and for example a sound coming from your left will arrive to your left ear earlier than to your right ear. Secondly, the same sound will be attenuated on your right ear due to the head shadowing effect. Furthermore, there are sound paths that will hit your torso first and are then delayed and reflected to your ears. Additionally, all these effects are strongly frequency dependent. Your ears are used to all these kind of “artifacts” and decode them as spatial information.

KLANG’s 3D in-ear mixing technology imitates exactly what would happen to e.g. instrument signals around you before they hit your ear drums. A specially processed signal arrives at your in-ear or headphones drivers and contains all spatial cues your ears need to get a full 3D impression to let you immerse into a realistic and transparent sound field.

Our hearing always relies on spatial cues and is trained to listen to different directions. Once we concentrate to listen to sound coming from a specific location (hitting our ears from a certain angle), the other sounds from other directions are blended out immediately. With KLANG, these spatial cues are delivered through your in-ears and headphones and your ears and brain can process sound the way they are used to. This feels very natural and is not tiring for your ears. That is the reason why many musicians feel relaxed and focused when playing live or in the studio through KLANG’s 3D mixing, even during long concerts and sessions.

Without KLANG? If your ears don’t find these spatial cues in your sound mix, you have to concentrate on specific timbres or sounds of instruments. What will happen then is that you have to actively think about how for example a violin sounds like and then find the violin-like sound character in  the one-dimensional sound mix. This is a very challenging task for your ears and your brain. No matter how experienced you are with this, KLANG’s 3D in-ear mixing will noticeably relieve your ears!

Yes. The 3D processing already delivers all spatial cues your brain and ears need to distinguish directions where the sound is coming from. Without motion tracking, the mix will be 3D (left, right, in front, behind, above or below you – all sources externalized) but when you turn your head, your mix will stay the same.

It depends.

If you want to use your KLANG processor as a personal monitoring system, all musician should have access to their own mixes.

This can either be done with KLANG:app on smartphones or tablets or with KLANG:kontroller. Of course these work simultaneously, so it’s completely your choice.

Get in touch with our support team via our website and include the serial number of your device, a brief error description and describe what happened before the issue arose. If this occurred right after a KOS update via USB, please also send the log files created on the USB drive during the KOS update procedure, and include the last KOS version installed on the device.

1. Start a video recording of the display or LED and restart device
2. Perform a USB KOS Update; it might take up to 30s until display or LEDs are lit
3. If display shows “MMC error”, MMC card needs to be re-seated/renewed
   – :kontroller needs to be sent in for service, last display is blinking yellow
   – :vokal/:konductor: Remove the cover plate (4 screws, rear panel, right side, opposite to power inlet), re-seat micro SD card(s): push on the card, take it out, wipe contacts, push in again. Do the same for the other card on :konductor. Power :vokal/:konductor on.
   – Remove DMI-KLANG. Re-seat micro SD card. Push on the card, take it out, wipe contacts, push in again. Install DMI-KLANG again.
4. Perform a KOS Update via USB.
5. Replace micro SD card / Customer support will help you with this process.

It supports all sample rates that are supported by the host (console or Audio DMI card in slot 1 of an Orange Box) and it will follow automatically.

YES. KOS 5.6+ required.

Yes, that is possible with KOS 5.5. Find out more…

With KOS 5.4 it became possible to change the stereo panning laws on 2nd Generation KLANG processors.

The panning law used before KOS 5.4 is KLANG1. Along with the auto mapping feature for the DiGiCo console integration, the panning types D1 and D2 are introduced, these are identical to the type 1 and type 2 panning laws on a DiGiCo. By creating a new KLANG show file from scratch (Load default/defaultOff) panning law D1 is used. Mixes created on a DiGiCo with panning law type 1 while therefore sound identical when imported to as a starting point to KLANG.

The STEREOK3 panning laws are pseudo binaural pannings with different head geometries. Use these panning laws when some signals need to remain in Stereo (e.g. because less coloration is required) and still get improved sound transparency.

Set Stereo Panning Law is stored in a KLANG show file and will be recalled when loading a show file. It affects all mixes.

Login with KLANG:app to your :konductor. Go to CONFIG > INFO > SET > Update DMI cards.

The DMI card firmwares are included in the KLANG Operating System (KOS). A KOS Update might offer new firmwares, but they will never be installed automatically. Head to CONFIG > INFO to check if a new firmware is available for your DMI cards.

Find out more in our detailed guide on DMI-Card Updates & Settings.

DMI-KLANG can only be installed in slot 2 of a DiGiCo OrangeBox. Slot 1 is always the clock master, and since DMI-KLANG does not provide an audio clock, it has be in the second slot and get its clock from an audio IO card in slot 1.

KLANG:app supports four user modes that distinguish between musicians and engineers/system administrators. These modes can be switched by pressing and holding the CONFIG button for 3 seconds.

For more details, see our manual KLANG:app Select User Modes and Learn more on how to optimize the feature set and GUI for your application as an engineer, system tech or musician.

DMI-KLANG can be installed in the DMI slots of the following DiGiCo consoles:

• Quantum 7
• Quantum 5
• Quantum 338
• Quantum 225

Depending on the IO configuration, KLANG:fabrik can create up to 16 3D in-ear mixes. Each mix consists of a stereo output pair. KLANG:fabrik’s flexible routing scheme allows to route mixes from the 3D in-ear mixing processor to any digital output interface and to the 8 stereo analog XLR outputs.

8 mixes can be routed to the 8 stereo XLR outputs. All available mixes – including all mixes that are routed to the XLR outputs – can be routed to any digital output interface. E.g. you can route the other mixes which are not already routed to the analog outputs via Dante to KLANG:quelle.

One power supply is sufficient to power KLANG:fabrik. As common practice for professional touring audio gear, KLANG:fabrik offers a second power supply for redundancy. Connect it to a second, redundant power line if possible for extra safety if the first power line has an issue.

It can also be used to swap the power lines without any interruption of the audio stream. Connect the second power supply to a another power line. Check that both power supplies are active in the info screen e.g. via KLANG:app. Then disconnect the first power supply.

Please find information on the IO configuration for KLANG:fabrik here.

KLANG:vier can create 5 individual stereo mixes. A mix always consists of a stereo output pair. KLANG:vier offers 4 stereo headphone outputs and line level outputs. Mix #1, #2, #3, #4 are permanently routed to the 4 stereo analog outputs.

All 5 mixes are available via Dante. Hence, #5 can only be accessed via Dante and e.g. routed to a KLANG:quelle headphone amp or to a Dante breakout box or Dante enabled digital mixing console.

KLANG:vier can create 5 individual 3D mixes. A mix always consists of a stereo output pair.

24 input channels can be processed including EQs in 44.1kHz and 48kHz.

In case KLANG:app shows a warning that the power supply of KLANG:vier or KLANG:fabrik needs to be checked. Please contact customer support and include a screenshot of the info screen. Email to support@klang.com

In case the voltage is below 4.7V the unit requires service immediately.

For KLANG:fabrik, we recommend to use both power supplies for stability reasons.

Yes, that is possible.

For KLANG:fabrik, this can be configured in KLANG:app’s routing menu.

For KLANG:vier, KOS version 2.2.4 or higher and Dante Firmware 1.1.0 or higher is required. Details can be found here: https://www.klang.com/blog/adat-thru/

You can’t see your KLANG device in Dante Controller?

You have probably configured your Dante module for a static / fixed IP address and now need to discover the unit’s IP address and revert it to factory defaults.

Please check out our detailed guide: How to recover and reset your Dante module’s fixed IP settings

Yes. Dante has the great advantage that it takes care of audio clocking almost automatically. If you use e.g. KLANG:vier with an ADAT input or KLANG:fabrik with ADAT, MADI or external Wordclock, or KLANG:vokal with MADI and you want to integrate the KLANG devices to a Dante network, the clock has to be configured manually.

Set the KLANG devices to the clock source of your choice. In Dante Controller, tweak the clock settings of this KLANG device in the “Clock Status” tab. Enable the “sync to external” and “preferred master/leader” for this unit. Now, the internal clock of the KLANG device will feed the entire Dante network and you can route audio from your KLANG processor e.g. to a :quelle or :kontroller.

Make sure the KLANG processors are not set back to Dante as the clock master before unchecking the “sync to external” setting again. Otherwise, you will end up with a clock loop.

Dante is a proprietary audio over IP (AoIP) network protocol developed by the company Audinate. It is extremely versatile, robust due to redundancy features and still easy to use. Instead of using analog multicores and several digital interface cables, Dante allows you to transmit hundreds of channels of audio with high fidelity sound (24 or 32 bit, 44.1–192kHz) across hundreds of meters with only one network cable, and maybe a second one for seamless redundancy.

Most manufacturers in the field of digital mixing consoles have already incorporated Dante into their products e.g. by supplying expansion cards. Among them are Yamaha, DiGiCo, Soundcraft, SSL, PreSonus, Midas through Klarkteknik converter, Behringer and many many more. Converters between digital formats or to analog inputs and outputs are available in various configurations. DAD/NTP, Focusrite, Auvitran are just a few examples for brands offering great connectivity possibilities.

Since 2015, Audinate’s Dante modules can be firmware updated to offer AES67 support enabling network audio connectivity to an ever wider range of products.
