How does directivity control work?

Duran Audio has developed two key technologies that allow the directivity of AXYS® loudspeaker arrays to be controlled electronically. They are: Digital Directivity Control (DDC) and Digital Directivity Synthesis (DDS).

Used in conjunction with proprietary AXYS® software, DDC and DDS enable sound designers to accurately create loudspeaker systems that deliver sound precisely where it’s required, while keeping it away from reflective surfaces such as walls. The result is more coherent, intelligible sound.

Digital Directivity Control (DDC)

DDC is a multi-channel loudspeaker array technology, where each loudspeaker channel has its own dedicated audio path through the Digital Signal Processing (DSP) and amplification.

Each loudspeaker, or group of loudspeakers, is given its own unique set of filters, which enables designers to electronically manipulate the vertical dispersion of an array. In other words, the beam of sound can actually be moved up or down. This makes DDC the perfect solution for venues with a flat listening plane

Digital Directivity Synthesis - DDS

When a solution for a more complex listening plane is needed – such as a raked seating area or split level – DDS gives the designer even more flexibility than DDC.

DDS gives users the power to synthesise any desired 3D radiation pattern from a loudspeaker array to meet the specific needs of the venue. The only limitations to the flexibility of the system are the physical constraints of a pre-defined array – transducer distance, array length etc – all of which requires the usual amount of detailed consideration at the system design stage.
