:app menu – CONFIG > INFO

This screen shows you information on the status of your hardware unit. It contains information on the software, firmware and hardware version of your KLANG device and its serial number. Most important for quick troubleshooting is the associated IP address. Information on the power supply helps to find out whether a power line is switched off (KLANG:fabrik only, redundant power supplies). The Audio clock settings show you the sample rate and the clock source at a glance.

On the bottom right corner you will find a list of the Local IPs, e.g. of the device running KLANG:app following by the receive port e.g. 9111. In the second line the UID of KLANG:app is shown followed by the version number and the app release date.


More useful statistics are shown to better indicate things to look at. The Net value shows the network control paket latency. Along with the packet losses a problem, e.g. network loop or misconfigured switch can be found more easily.

This latency does not have to do anything with the audio latency.
  • DSP: DSP missed blocks. Should be zero. If not decrease sample rate or i/o config.
  • FT:
  • EC: Error Counter since Boot. Should be zero, but can eventually show an error. If it increases contact customer service.
  • TEC: Total Error Counter over all boot cycles
  • BC: Number of boot cycles

Log Files

Copy Log to Email will transfer the main Log via network to KLANG:app and paste it to the clipboard and open an email with this content.

Copy Log to USB transfers the LOG to a USB drive and this also includes all presets/show files stored on the KLANG hardware (see below).

Preset Transfer via FTP

Click on “Copy Log to Email”. KLANG:fabrik / KLANG:vier will open an FTP read only server on port 21 with the IP address shown in the info screen. Use an FTP programm to connect.

On Mac OS X you can connect directly with Finder. In Finder choose Go -> Connect to Server. Enter ftp://<yourFabrikIP>:21 and click Connect. You will see all presets saved on the hardware anc you can copy them to your Mac for Backup. The FTP is read only, so you cannot upload presets to your hardware unit. 


Advanced Features

Advanced features for pro users and IT experts only.

Go to CONFIG > INFO > Set > Advanced

Set Unit Name

By default the Unit Name equals the serial number of the device. KLANG:app alphabetically sorts devices based on the unit name. 

Find out how to use the Unit Name to cascade units.

Enter a name and assign it to the unit by clicking on SetUnset reverts the unit name to the serial number.

Set Fixed IP

Please note that the KLANG personal mixing system and the Dante module included in :fabrik, :vier, :vokal and :kontroller are different network devices and have different network settings, i.e. they have different IP addresses. This setting here will change the IP of the KLANG personal mixing system control server. If you want to change the IP address of your Dante device go here. 

We highly recommend to leave the IP settings to DHCP client only.

This will assign a second IP – which is fixed – (not the Dante Module but the 3D in-ear mixing server). The first IP will always stay on DHCP client, so you can access your unit even if you forgot your fixed IP address settings.

Please note: if you have an DHCP server running on your network and you want to use fixed IPs make sure that these IPs do not overlap with the ones assigned by the DHCP server. KLANG:fabrik/ KLANG:vier will have 2 IP addresses (+1 for the Dante module). KLANG:app will only show your hardware once in the device list depending on which IP address appears first.
We highly recommend to leave the IP settings to DHCP client only.

Assign a fixed IP in the first line, e.g.

Subnet Mask in the second line. Make sure the subnet mask on all devices running KLANG:app and on the processor are EXACTLY the same. Otherwise the discovery of the processor will not work.

Default Gateway (GW) in the third line. (default: empty. Leave blank if not required, or the same as the IP but with a .1 in the end)

If Fixed IPs are used, please make sure to configure the network settings of the remote devices running KLANG:app accordingly. It is recommended to specify the standard gateway and DNS server as well to prevent e.g. device discovery issues on iOS or macOS. If unsure just enter the IP address of your KLANG:fabrik but substitute the last digit to x.x.x.1 and enter this IP for DNS server and standard gateway in your system network settings e.g. on iOS or macOS.

Factory Reset

This will delete all settings and presets stored on the unit. You need to enter the last digits of the serial number manually to avoid deleting all settings by accident.

Advanced Gain Structure

KLANG’s mixing engine uses floating point and hence cannot clip internally and the engine can by default handle gains above 0dB without any issues. In some cases the digital input signal is too low due to unbalanced gain structure in the mixing console. The new CONFIG > Set > Advanced > Max. Fader Gain +6dB option increases both the channel and the master fader range up to +6dB. This yields in a maximum digital gain benefit of +12 dB.

The setting Max. Fader Gain +10dB increases the channel gain limit to +10dB but the master volume is limited to 0dB. This is useful for the DiGiCo console link.

The default can be restored by selecting Max. Fader Gain +0dB on all KLANG:apps

DON’T show demo mode

This will hide the demo mode from the Connect screen and prevent users to accidentally activate it during a show.

Reset error counters

Reset all error counters but leave all presets on the hardware.

Verbose Logging

Activate this function if requested by KLANG support.
