:vier | Quick Start Guide

Congratulations on your very own KLANG:vier and welcome to the world of Immersive In-Ear Mixing! To implement KLANG:vier into your system as fast as possible follow the few steps below:

What you need

faq icon to expand accordian

  1. Computer with KLANG:app – install and familiarize yourself with the app here: KLANG:app Overview #1
  2. Dante Controller plus Dante enabled product/Dante Virtual Soundcard or ADAT interface
  3. KLANG:vier
  4. Network cable
  5. Nice to have: Wifi router

Step 1 | Power up KLANG:vier

Connect a power chord to your KLANG:vier and switch the power on.

The LED will turn to purple when KLANG:vier is operable.

Step 2 | Control Network

You need to open a network to connect your laptop or tablet/smartphone to KLANG:fabrik. We recommend using a road-proof router with two independent WiFi networks with 2.4 & 5 GHz.

Connect your router to KLANG:vier’s NET Ethernet port.

The Network activity LEDs will start to light up and blink.
Please note that KLANG:vier uses two different IP addresses. The first IP address belongs to the 3D in-ear mixing server and is important for all remote devices using KLANG:app. This IP address is shown in the info screen on the touch screen. It is either provided by a DHCP server (e.g. inside a WiFi router) or it is a self-assigned zero-conf IP (starting with 169.254.x.x) if no DHCP server is present on the network when KLANG:vier is started. 

The second IP address belongs to the Dante card and can be set via the Dante Controller.

Step 3 | Download KLANG:app

Open KLANG:app and go to CONFIG > CONNECT and choose your device.

If the computer is connected via Ethernet, WiFi should be disabled as running two active network connections could interfere with the device discovery process.
No devices found? Check if one of the available IP addresses of the computer as shown in KLANG:app is in the same range as one of KLANG-DMI’s IP addresses (e.g. via KLANG control panel if the card is installed in a DiGiCo console or via the OrangeBox controller if installed in an Orange Box or via KLANG:app > CONFIG > INFO if the card is installed in a KLANG:konductor). Further, check computer’s network adapter for connection status.

Step 4 | Connect your Audio Source

KLANG:vier is able to create five 3D headphone mixes from Dante/AES 67 or ADAT signals. Dante Controller is needed to route the audio from your Dante mixing console/Dante Virtual Soundcard to KLANG:vier. Visit the Dante Routing Blog for detailed routing information.

If you don’t have any Dante enabled products, you can send audio signals with your Laptop and a Dante Virtual Soundcard instead.

Or use optical cables and connect them to your ADAT compatible interface and KLANG:vier’s optical inputs. If you are using the optical inputs, take a look on our ADAT to Dante feature.

Step 5 | Routing

To change the internal routing (Dante or optical inputs), you need to be in Admin mode. Press and hold the CONFIG label for 3-5 seconds and select Admin. When using ADAT, connect the cables and use KLANG:app’s routing screen to route audio from optical inputs to the 3Diem sinks and set the clock source to optical inputs as well, if your console is clock master.

Step 6 | Enjoy Immersive In-Ear Mixing

  1. Go to CONFIG > CHANNELS and set colors, icons and edit channel names. Assign to individual groups.
  2. Create immersive in.ear mixes using STAGE and FADERS

FAQ

 

:vier

What kind of network switches work with Dante?

faq icon to expand accordian

Generally, managed switches with deactivated EEE are preferred for Dante networks. Follow this guide to find the features you need.

How does Dante Follow / AutoConnect work?

faq icon to expand accordian

KLANG:kontroller can be configured to automatically patch Dante to the mix output of a KLANG processor.

 

Follow these steps to setup Dante Follow.

How many :apps can be connected to KLANG immersive processors?

faq icon to expand accordian

Our products are designed and tested to be used with at least 1 :app or :kontroller per mix, plus 2 :apps for engineers. In most cases is is possible to use even more apps, there is no fixed limit.

How many KLANG devices can be connected?

faq icon to expand accordian

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’s 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 limitiation 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.

How can I store and recall presets?

faq icon to expand accordian

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.

More info on Preset…

How can I listen or CUE into mixes?

faq icon to expand accordian

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.

Which Sampling Rates are supported?

faq icon to expand accordian

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 rages 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 and :kontroller and :konductor can work with 48kHz and 96kHz and offer the exact same channel count / mix count with both sample rates.

 

What is a mix or an output? Is it mono or stereo?

faq icon to expand accordian

A mix (or :output as labelled on the back of e.g. KLANG:fabrik) always refers 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.

Do I need special headphones or in-ears to experience 3D sound?

faq icon to expand accordian

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.

Is it Personal Monitoring System or is it a tool for Monitor Engineers?

faq icon to expand accordian

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.

Why are all other groups turned down if I increase the volume of one group?

faq icon to expand accordian

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.

What do the red or green icons above CONFIG stand for?

faq icon to expand accordian

From left to right.

“C” stands for Clock

  • green: clock sync is OK.
  • red: there is a clock error

Change and monitor clock settings in CONFIG > ROUTING.

“N” stands for Network

  • green: Connection and ping time to KLANG processor OK
  • orange/yellow: some pings did not come through or the ping time is very long > Network problems or processor overload
  • red: connection to KLANG processor lost or communication too slow > check network settings and processor.

Take a look at CONFIG > INFO more details.

 

“D” indicator (DiGiCo console is Init Master) /
“K” (KLANG is Init Master) indicator above CONFIG /
“T” (Throttling is active) network messages are currently slowed down as there is a lot going on.

  • <No indicator>: Mixing Console Link Mode is set to OFF
  • Blinking Green: Mixing Console Link Mode is set to Setup
  • Static: Mixing Console Link Mode is set to Active
  • Blinking Red: Link Mode is set to Active but NO Mix or NO Channel Mappings are set.
  • RED: Console Link connection not working / lost connection
  • YELLOW: Console Link connection issues, loosing connection
  • GREEN: Console Link connection OK and working.

How do I exchange presets between different processors?

faq icon to expand accordian

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.

More info on Preset…

What mixing consoles can be connected?

faq icon to expand accordian

Any digital mixing console with either ADAT / optical outputs or the Dante AoIP protocol or AES67 support or MADI BNC or Optocore.

How can there be 5 mixes when the unit has only 4 stereo outputs?

faq icon to expand accordian

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.

How many input channels and users can KLANG:vier handle?

faq icon to expand accordian

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.

Which Characters are allowed for Preset Names?

faq icon to expand accordian

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

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

How can I revert a fixed / static Dante IP?

faq icon to expand accordian

I cannot see my KLANG device in Dante Controller… You have probably configured you Dante module for a static / fixed IP address and you need to discover the unit’s IP address and revert it to factory defaults.

Please check our <a href=”http://klang.com/blog/reset-dante/”>dedicated guide to recover Dante devices.</a>

Warning – Power Supply Voltage – Service Required. What shall I do?

faq icon to expand accordian

 

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.

 

 

How can I connect digital audio interfaces and consoles?

faq icon to expand accordian

KLANG:vier offers ADAT, Dante/AES67 interfacing. KLANG:fabrik offers optionally MADI and is a versatile audio format router.

A detailed overview of further audio standards and possible converters to connect 3rd party equipment to KLANG products is shown on our blog here…

Can I route incoming ADAT signals to Dante?

faq icon to expand accordian

Yes, that is possible.

For KLANG:fabrik, this can be configured in KLANG:app routing page.

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…

http://klang.com/blog/adat-thru/

My system is not booting. What can I do?

faq icon to expand accordian

Please check again without any network or audio cables connected to the devices. For KLANG:fabrik make also sure to connect both power supplies. Make sure no USB drive is inserted. Check that the powerline is working properly. If your device is stuck in the boot process, proceed with the step by step guide shown in the recovery procedure here…

How can I update the Audinate Dante firmware?

faq icon to expand accordian

You will find a step by step guide in our blog here…

Can I use a different word clock source for the Dante network?

faq icon to expand accordian

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 or 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 in before unchecking the “sync to external” setting again. Otherwise, you will end up with the clock loop.

 

Can I remote control the system via MIDI or OSC?

faq icon to expand accordian

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.

Why is the KLANG sound so much more transparent?

faq icon to expand accordian

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:fabrik and KLANG:vier this spatial cues are delivered through your in-ears and headphones and your ears can work in the same way they are used to do. This feels very natural and is not tiring for your ears. That is the reason why many musicians still feel relaxed when playing live or in the studio through KLANG’s 3D mixing.

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 happens then, you have to think e.g. how a violin sounds like and then find the violin like sound character in a one-dimensional sound mix. This is a very challenging task for your ears and your brain. No matter how experienced you are with this, 3D in-ear mixing relieves your ears.

Do I need an iPad, Tablet or Smartphone?

faq icon to expand accordian

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.
