Active Beam Shaping, Self Powered, Loudspeaker Array

The Intellivox-DS280 offers excellent speech intelligibility even in demanding acoustic conditions. The Intellivox-DS280 is capable of providing a constant sound pressure level over a distance of up to 35 m, although a substantial extension of this range can be achieved in less demanding acoustical conditions. The sixteen, custom designed, 4” loudspeakers are driven by an eight channel class-D amplifier, powered by a sophisticated switched mode power supply, all of which combine to ensure years of reliable operation. The loudspeakers themselves are arranged in accordance with our patented algorithm.

An extensive set of surveillance functions have also been implemented to meet the stringent demands of typical Voice Alarm (life safety) applications. The unit can be controlled using our proprietary WinControl software which offers user friendly control of the beam steering parameters, audio processing, pre-sets and surveillance features. Its compact array length makes the Intellivox-DS280 suitable for easy and unobtrusive implementation in even the most architecturally sensitive environment. The low frequency response of the system can be easily extended using a JBL sub woofer system.

Aiming Technology
Digital Directivity Control™ provides beam-STEERING, based on aiming parameters.
DC models
WinControl – Allows you to set the DDC beam-STEERING settings. This same software communicates with and uploads the settings to the speaker(s)

Complex Digital Directivity Synthesis™ provides complex room coverage via beam-SHAPING. The shaping algorithm is based on a model of the room or listening space, resulting in consistent SPL and consistent frequency response from place to place within the listening space.
DS & DSX models
WinControl™ – RAPID DDS™ (which is built into WinControl) selects the right DDS™ settings based on basic room and usage parameters. This same software then uploads the setting file to the speaker(s) by pressing “Apply”.

DDA™ (Digital Directivity Analysis™) for modeling a listening space and computing DDS beam-SHAPING algorithms. Plus, WinControl™ for uploading the settings file to the speaker(s).
Software Systems
  • Directly controls DDC™-driven products for: 1) aiming axis, 2) opening angle, and 3) focus distance. 
  • It is also used to set other audio parameters, including 8 parametric EQ bands, delay, AVC (automatic volume control) functions, volume level, surveillance related parameters, pilot tone detection, priority switching, 8 full presets, and more. 
  • Enables the upload of DDA™-calculated DDS™ directivity files to the speakers. 
  • RAPID DDS™ allows creation of DDS™ files to speakers without having to use DDA™.
DC, DS and DSX Models

  • Integrates geometric modeling, direct sound prediction, statistical room acoustic prediction, graphic visualization, radiation pattern optimization and generation of output filter files.
  • The file is transferred to WinControl™ for uploading to the DSP-units of the speakers.
DDA supports all products (DC, DS and DSX) but you can only export beam SHAPING settings for DS and DSX.
