1. Precise acoustic simulation

 

K-framework3 allows you to: import 3D venue models, ensuring a simulation based on precise and real-world measurements; select the desired loudspeakers, from K-array ecosystem; create your configurations and simulate with precision frequency response, SPL distribution and many others. The result is a reliable, intuitive, and comprehensive tool that supports every stage of your project.

In addition at the end it can automatically generate a detailed report about all system parameters, acoustic predictions and performance data that is ready to be shared directly with clients or collaborators, making communication more efficient and documentation more professional.

1.1 Electronic Beam Steering

 

Achieved by applying dedicated FIR filters to each element of the array, EBS allows the system to tilt, focus, or shape the vertical and horizontal dispersion of the sound beam without physically moving the loudspeaker, directing energy toward the listening area. This enables to: adapt the frequency response to match a target listening area; create multiple listening zones with different coverage; predict and evaluate real-world system behaviour in the design phase; optimize SPL distribution and frequency response uniformity.

1.2 Amp assignment

 

Beyond selecting the right amplifier for each loudspeaker, K-framework3 can automatically map every channel to the corresponding speaker, reducing time, potential errors and ensuring perfect consistency between the design and the real-world installation. This capability becomes essential in EBS applications and large-scale projects, where multiple drivers can be routed with absolute precision making installation faster, clearer, and far more reliable.

1.3 Speech Transmission Index (STI) Calculation

 

  • Predicting Intelligibility: K-framework3 integrates STI for evaluating how intelligible speech will be. This goes beyond simple SPL mapping, allowing engineers to assess the clarity of spoken word reproduction in real-world conditions.
  • Simulation in Enclosed Spaces: The software allows to input venue-specific acoustic parameters, such as reverberation time and absorption coefficients of materials, to simulate their influence.
  • Design Phase Advantage: By predicting intelligibility already at the design stage, K-framework3 enables system engineers to: anticipate critical issues in speech clarity; compare different loudspeaker placements and configurations; optimize the system for musical and spoken word performance.
  • Reliable Decision-Making: This integrated approach ensures that every project can be validated not only for sound pressure distribution and frequency response, but also for speech intelligibility.

2. Network Management

 

With K-framework3, managing your network of amplifiers is fast and intuitive. The software automatically discovers all connected devices, allowing you to select which ones to add to your workspace. You can also view where and when each amplifier was last edited, ensuring greater visibility and consistency. Thanks to this streamlined workflow, it becomes effortless to connect the amplifiers in your workspace to the real units on your network, making the transition from design to deployment seamless and reliable.

3. Setup Session


The Set Up session is designed to simplify system preparation and organization. Here system designers can easily group amplifiers and loudspeakers, creating logical structures that streamline both configuration and control. It allows the creation of specific routing paths, ensuring that each signal is directed to the correct destination with maximum flexibility. Once the architecture is defined, the required presets can be loaded directly onto the amplifiers, guaranteeing consistency and optimal performance.

4. The Perfect Tuning


Once the system has been set up, K-framework3 provides a complete environment for on site tuning and optimization. You can easily apply filters, adjust delays, and fine-tune every detail of your system to achieve optimal performance and sound quality.
