Over the past decade or more, digital signal processing has become a critical component of sound reinforcement system. EAW has led the industry in developing software tools that model, predict and ultimately control loudspeaker performance.
Starting with F-Chart™, our original array modeling software developed to support the creation of the KF900 Series, EAW engineers have created software tools that advance our core engineering approach of integrating multi-component systems into unified entities.
EAW engineers have custom-developed all EAW software products using an approach that implements DSP in ways that are unique to EAW. These closely-guarded methods deliver optimum performance from EAW loudspeaker systems. Even full range systems with internal, passive crossover filter networks benefit from EAW Focusing™, the latest innovation from EAW’s software team.
Most EAW loudspeaker users rely on the UX Series of digital processors to deliver EAW Greybox™ and Focusing™ settings, using EAW Pilot™ to interface with the processors.
EAW supports 3rd-party processing platforms for amplifiers with onboard DSP from Lab.gruppen and Powersoft. Each of these amplifiers’ onboard processors can install Greybox™ settings and adjust the user-controllable parameters.
Resolution™ 2 significantly upgrades functionality by adding three-dimensional capabilities, as well as modeling and control support for EAW Anya™ systems.
EAW Resolution™ is a powerful and easy-to-use simulation software that accurately predicts the performance of multiple arrays within a venue. Driven by EAW’s proprietary F-Chart acoustics modeling software, Resolution is more accurate and powerful than previous generations of software by utilizing measured 3D acoustic data. It supports multiple EAW products, meaning just one piece of software fulfills numerous requirements.
Our most recent update (22.214.171.124) further improves functionality with the addition of Otto and the Otto Array Assistant, significant improvements to the Network Configuration View for Adaptive Systems and many more improvements / general bug fixes. For more information, see the 126.96.36.199 Release Notes (below).
EAW Pilot – Deliver EAW Greybox settings to UX Series processors or directly connect to NT Powered loudspeaker systems.
EAW Pilot™ delivers Greybox™ settings for EAW loudspeaker systems and lets user control any user-addressable processing parameters. Pilot™ can interface with UX Series digital processors, EAW’s NT Powered loudspeaker systems.
Regularly updated with the latest EAW signal processing innovations, EAW Pilot allows users to apply EAW Focusing™ to an ever-expanding list of products for which they have been developed.
December 2014 — EAWPilot v1.2.22 released, providing updated NT firmware. (see release notes for details).
June 2013 — Greybox v1.24 released, including settings for QX300 range.
DSA Pilot does not attempt to replace the designer. Indeed, it is helpful to develop a detailed sketch showing loudspeaker placement and horizontal coverage before working with the software. When the basic design is set, start by building the total system in the Network screen. Select pre-configured clusters ranging from one to several DSA Series modules to suit the cluster’s output and control requirements.
Now, create a coverage area profile for each cluster. Define the size and slope of the vertical coverage area’s floor and input the cluster’s mounting height. DSA Pilot will display the ideal vertical coverage beam as well as the cluster’s current vertical beam. The user can adjust the cluster’s beam manually or DSA Pilot can optimize the beam to match the ideal. Results can be exported to EASE 4.0 for display or further study.
Finally, the user can address settings for the clusters as a whole such as parametric EQ or gain and delay settings for secondary clusters in a larger system. Once the system is installed and connected, DSA Pilot then seeks out and identifies all clusters and loudspeaker modules on the network. The user selects an identified loudspeaker, activating an LED on the enclosure. Each DSA Series module is identified and associated with its mate in the design, confirming that the system is properly installed. DSA Pilot then determines if any groups in the system should be treated as clusters or individual modules. In a matter of seconds, DSA Pilot adjusts each module’s DSP setting in conformity to the design, and the system is ready for use. A listening test should prove satisfactory, and the user is left to adjust front-end equalization to taste.
As its name suggests, an EAW Greybox™ is a less-restrictive version of so-called “black box” software that does not permit any user adjustments.
EAW applies many proprietary techniques in the digital signal processing field, and the Greybox™ technique ensures that we maintain our closely-guarded secrets. Also and to ensure optimal performance, users should not be able to access some aspects of loudspeaker and/or system control.
However, the educated, well-trained user can improve the ultimate, in-application performance of an EAW loudspeaker system with access to key parameters like EQ and signal delay. Thus an EAW Greybox™ allows users to adjust these parameters while keeping mission-critical functions secure against accidental changes.
