Control. Interface. Logic. Script. Data. Distribution.

Everybody involved in modern AV installations and projects knows about the challenges of having numerous devices from numerous different manufacturers all speaking different control protocols… Haven’t you ever dreamed about a single communication and abstraction layer for the entire AV system network?
Could you imagine a system where the connection between a touchpanel button and a contact closure is made with a single Drag & Drop operation? And could you imagine that you can also Drag & Drop connections between projector controls, building bus systems / light switches, DMX, Art-Net, MIDI, video or audio controls, PC controls, Databases and Outlook Calendars just to name a few examples?
We know about the challenges and have invented the most technologically advanced (A)udio (V)isual (I)nput (O)utput system. Avio is a clean sheet design which covers all aspects of a modern AV installation:

Avio connects just everything

How does Avio work?

Simple. Clever. Stable.

Avio is a network protocol and sophisticated control logic system developed for AV installations. The idea behind Avio is to bring all devices of an AV installation like media servers, show controllers, lights, effects, projectors, switchers, scalers etc. to the same abstraction layer.

All device ports and controls show up automatically in a tree view topology of the network and can be “wired” to each other using a simple Drag & Drop editor. It is possible to connect the button of a touch panel with a light bulb, but it is also possible to connect the gesture controls of a Microsoft Kinect unit with the video parameters of a media server. 


Network Topology

Decentralized. Fail passive. Automatic.

Do you know legacy AV control solutions where central servers were handling all connections and control logics? The disadvantage is that if this server fails the entire installation is down and maintenance is immediately required. Avio follows a different approach: Its design is decentralized which makes it fail-passive. There is no central server or computer required: Every Avio device communicates directly with the other devices and stores its connection information. If one device fails, only the affected connections are interrupted and the only maintenance work required is to exchange this single device and use a new one with the configuration (which is stored on an SD card) of the existing one.

Automatic. Safe. Verified.

Avio is not just a simple control protocol converter. Once a device is embedded into the Avio network it is permanently monitored: Once a value is sent from one device to another, Avio makes sure that the values have arrived safely and uses a combination of different network technologies in the background to get this done. Data can be scaled and converted into different formats automatically or by using manual parameters.



DMX. RS232. Art-Net. KNX. MIDI. Audio. Scheduling. Logging.

Have you ever tried to describe your installation’s features and functions in short sentences? Its challenging isn’t it? We tried to do our best to give you a brief introduction about what Avio can do to make your daily life in systems integration and show control easier and more comfortable. Please do always note that Avio merges together all these different worlds of technology to a single configuration, control and visualization layer.

Social Media Integration

Social media content can be integrated into the AVIO network and can be made available to all system components. Using AVIO this way, it is possible to use social media content as part of information displays in corporate environments or for realising interactive displays in museums or theme parks.


You would like to realize a sleek media/room control solution which can be controlled via web enabled devices such as smartphones or tablets? With Avio, your control solution does  not require any PC or server.


In a lot of AV installation projects building functions such as lights, shades or climate are controlled via the KNX bus. KNX projects can be easily imported into Avio and the data points can be linked with all other components within the Avio network. Whatever they are: Control, visualisation or information.


Interaction and gesture control becomes more and more popular. The difference between a “nice effect” and a properly functioning solution is in the details. Depending on the application it is neccessary to select the right interfaces and sensors and sensor data has to be filtered and smoothed. Myo armbands are measuring muscle impulses and features gyros and earth field sensors and is natively interfaced in our control network Avio.


Avio now features a new data recorder which can be used for example to record DMX or Art-Net streams. These streams can be imported in our software to use or modify them.


Avio can parse contents and values from XML files. This can be used for example to retrieve values from a website and reuse it in the show control network.


MIDI has been a standard communication protocol for music devices, audio consoles and digital music instruments for decades. We have fully integrated MIDI into our Avio network so that MIDI devices can be part of an installation or show.


Building automation integrated.

KNX has been one of the most established bus system used in building automation for more than 20 years. Avio allows to import the KNX configuration of the whole building making all building functions such as the lighting, air conditioning, security systems, weather data and more available on the Avio network.


DMX has been the standard protocol for controlling staging and installation effect devices such as moving heads, scanners, fog machines etc. for years. It is stable, simple and well established. Avio brings DMX universes into the Avio network and makes DMX inputs and outputs available to all other devices in the installation.


Art-Net is an Ethernet based communication protocol for staging setups and themed attractions. It is fully integrated into the Avio network for connecting Avio devices such as media servers to lighting consoles, or show control timelines to lights and other effect devices.


Ethernet. Serial. IR.

Third party devices such as projectors, switchers or scalers can be integrated via their RS232 or Ethernet connections into the Avio network. Avio wraps all the third party device functions and monitors their execution and device status. Drivers translate the commands back and forth on the Avio network and can be easily created using our own software wizard. Although configuring drivers is straight forward our support team is happy to assist if new devices have to be added.


Audio playback is an essential part of every installation. Avio can manage playback, volume controls and many other Audio tasks.


Avio fully supports innovative human/machine interfaces such as the Microsoft Kinect interface, which uses 3D microphones, cameras and distance sensors to track people and their gestures. These gestures are connected and available on the Avio network for further use within the AV installation


Avio supports various interactive collaboration tools such as the Microsoft Kinect, RadarTouch, LeapMotion controller or the innovative Myo gesture control armband.


PCs can be remote controlled and monitored using Avio.


Content Production. Playback. Timeline. Live. Control.

How can I get my themed attraction react on the prevailing weather conditions? How can I send E-Mails to visitors with information retrieved during their stay at the museum? Although Avio can handle a lot of automatic scaling and data converting sometimes it is needed to do some more sophisticated calculations and logic functions. Avio has its own Lua scripting interpreter which allows for sophisticated programming if something special is required. Although programming Lua is straight forward our support team is happy to assist.

There are numerous scripts already included with the Avio distribution such as E-Mail, Mathematics, Counter, Compare, Delay, Multiplex, Value Conversion, Weather or File I/O.
