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 to start

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

Download: KLANG:app, Dante Controller (DC) and Dante Virtual Soundcard (DVS)

Connection from Scratch

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.

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.x.x.x) if no DHCP server is present on the network when KLANG:vier is started. The current release of the KLANG operating system does not allow this IP address to be fixed, but with KOS 3.0 this will become possible The second IP address belongs to the Dante card and can be set via the Dante Controller.

Step 3: Download KLANG:app

Find all KLANG:app versions for all operating systems here. 

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, feel free to visit our Dante Blog and learn how to send audio signals with your Laptop and a Dante Virtual Soundcard.

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.

Enjoy Immersive In-Ear Mixing !

Now you can start to create awesome 3D mixes with your KLANG:app. Also keep in mind that you can send your 3D mixes from KLANG:vier to Dante (KLANG:vier as transmitter in Dante Controller) and even the ADAT compatible inputs are converted to Dante streams.
