Just as KLANG processors and :kontrollers, KLANG:app devices can now be identified by custom names. 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.

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.

Yes, KLANG:app offers a simulation of the :kontroller interface. Follow this link for more details.

Yes. Follow this link for more details.

KLANG:app can now check for available :app updates. Follow this link for more details.

Many features of :kontroller can be activated and deactivated to offer the exact feature set required for the production. Follow this link for more details.

You can set values for specific parameters for channels in all mixes. Follow this link for more details.

Yes. Button and text sizes have been optimized to yield the best user interface on different screen sizes while still showing all available control elements. Follow this link for more details.

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.

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 here to determine the offset: https://en.wikipedia.org/wiki/Coordinated_Universal_Time

You only need a WiFi router, if you want to connect KLANG:app on smartphones or tables, 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.

This is a known issue with webroot.

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

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 significated percentage (e.g. up to 50%) of the network traffic might be dropped, but it is hard to troubleshoot as it still works from time to time. This issue has not been addressed properly by the manufactured of these computers, yet.

Solution: Use a USB Gigabit network interface.

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 interchangable between different immersive processors e.g. between KLANG:fabrik and KLANG:konductor.

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

The KLANG console integration is available on the following DiGiCo consoles

• SD series
• Quantum series

Yes. The KLANG DiGiCo Console Link requires a computer running KLANG:app for setup and for operation.

Yes, you can activate Dark mode/:kontroller blackout which turns all LEDs and Displays (except for the last one)off. This is particular 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 if your headphones are open or closed, electrostatic, 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.

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 and a very short time.

At the same time, our products and especially KLANG:app offers all features experienced sound engineers 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 > CONFIG (requires Admin mode to change this setting) > INFO > SET > Disable KLANG:app Relative Group Mixing

In order to change the behavior for KLANG:kontroller login with KLANG:app to your KLANG:kontroller (requires Admin mode to change this setting) > INFO > SET > Disable Relative Group Mixing.

: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 channel from the kontroller, without the need to resort channels. Hidden channels are still audible in the mix but cannot be individually tweak. However, if the group is changed in level these hidden channels will follow. https://www.klang.com/manuals/app-faders/#reorder-groups

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.

Presets are interchangeable between all KLANG immersive processors.

If the presets contains less input channels or less mixes these settings will be added from the default file. In case the preset has more mixes or more input channels than the processor offers the first mixes and first channels will be loaded until the maximum is reached.

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.

Preset names shall not include blank spaces or any special characters such as  \“#@,;:<>*^|?\\/ etc.

Allowed characters are ‘a–z’, ‘A–Z’, ‘0–9’, ‘-‘, ‘.’, ‘_’

Yes, that is possible.

KLANG:app, all KLANG processors and :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 controlled via MIDI / MCU.

There are also flexible third party converters from OSC to OSC or MIDI to OSC available, such as OSCulator. In this way, mixing console commands like snapshot recall or fader comnands can be converted. Additionally, tools like touchOSC can be used to design specific graphic interfaces if required.

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 –

It depends. If you want to use the KLANG processor a personal monitoring system all musician should have access to their mixes.

This can either be done with KLANG:app on smartphone or tablets or with KLANG:kontroller. This works of course at the same time, it’s completely your choice.

The Digital Rights Management (DRM) is sometimes causing an issue on Amazon Tablets. The tablet need 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 tables to the internet at least once every month.
