Remote Connectivity
The Kommander-KA amplifier unit features a built-in hot spot establishing a
local Wi-Fi network dedicated to remote control the amplifier with mobile
devices. The default local Wi-Fi SSID and unit IP address are printed on a
label located on the rear plate of the unit; a QR code for easing the
connectivity is printed as well. The RJ45 Ethernet port on the rear panel
allows to connect the unit to a local area network (LAN). Since every host on
a network must be identified by a unique IP address, the simplest local
network usually implement a router/switch with a DHCP server managing the
addresses allocation: by default the Kommander-KA unit is set to obtain a
local IP address from the DHCP server. In case a DHCP server is not present on
the LAN, the unit goes in AutoIP mode: in few seconds the amplifier
automatically selfassign an IP address in the range 169.254.0.0/16. A static
IP address can be assigned to the amplifier unit using the amplifier’s
embedded web app (Network menu).
Connectivity Reset
With the unit switched on, keep pressed the RESET button on the rear panel for
10 to 15 seconds in order to:
- Revert the wired IP addressing to DHCP;
- Activate the built-in Wi-Fi and reset the wireless parameters to the default SSID name and password The status LED turns purple while the RESET button is pressed.
The Kommander-KA amplifiers can be controlled remotely by a mobile device or
desktop PC/MAC.

The update procedure lasts in about 15 minutes: after updating the Kommander- KA amplifier reboots.
K-framework3
The Kommander-KA amplifiers can be remotely controlled with the dedicated
K-framework3 software available for PC and MAC on K-array website.
The K-framework3 is the managing and control software dedicated to
professionals and operators looking for a powerful tool for designing and
managing a large number of units in demanding applications.
https://www.k-array.com/en/software/
The K-framework3 operates in three modes:
- 3D – Design a loudspeaker system for your venue in a full 3D environment and make free field acoustic simulations;
- SETUP – import from the 3D design the active components into the workspace or build from scratch a PA system composed of active loudspeakers and amplifiers; use the input and output groups to allow full control of the system;
- TUNING – Manage and control the loudspeaker system in real time: optimize the performance of the loudspeaker system during the tuning session and control its
behavior in live events.
The K-framework3 can work either off-line with virtual devices or on-line with
real active loudspeakers and amplifiers connected over the same Ethernet
network.
The K-framework3 allows you to start designing the PA system off-line and sync
the virtual devices to the real ones on site, when the devices are available,
or import from scratch in the workspace the real active loudspeakers and
amplifiers available on the network. In both cases, in order to discover and
sync the active devices, both the PC or Mac running the K-framework3 and the
real units shall be properly connected to the same Local Area Network – LAN –
with star topology.
The network shall comprise:
- single PC or MAC, running the K-framework3 software with network interface 100Mbps (or higher);
- router with DHCP server 100Mbps (or higher);
- Ethernet switch 100Mbps (or higher);
- Cat5 (or higher) Ethernet cables.
A DHCP server is highly recommended even if the device units implement the zeroconf network technologies: if a DHCP service is not available, every device will self assign an IP address in the range 169.254.0.0/16 (auto-IP).
Discovery
- Ensure that all the units and the PC/Mac running the K-framework3 are properly connected to the same network.
- Power up the units.
- Launch the K-framework3.
- Open the Network window and launch the discovery: • If the K-framework3 finds two or more devices with the wrong ID, a dialog window appears where unique IDs can be assigned to the units.
- Once discovered, the real units are shown in the left columns, following the order of their ID number; if the workspace contains virtual devices of the same type you can eventually modify the IDs in order to match the units and allows the synchronization. The synchronization can be in either directions: Workspace-to-Real or Real- toWorkspace. Select the sync direction and synchronize all or the single units separately
Grouping
The working paradigm in the K-framework3 is to group the input and output
channels of the units in the workspace and adjust the system performance
within the groups.
Groups can be created working both off-line and on-line and are retained by
the real units even once unplugged: if a real device belongs to a group, the
group is re-created in the workspace during the synchronization process. An
active loudspeaker or amplifier might belong to multiple groups sharing its
features (eq filters, time delay, volume, etc).
**** The K-framework3 synchronization process reset to default the EQ, delay
and volume parameters edited with the K-array Control mobile app and the
embedded Web app.
A. In Setup mode: set the unit local parameters (presets, routing, input
gains, limiters, etc).
B. Add INPUT and OUTPUT groups as needed.
C. Assign the units’ channels to the groups.
D. Switch to Tuning mode.
E. Align the system using the tools available on the groups (eq, delay,
polarity,etc).
Service
