The AXYS^® Intellivox-DC500 is the flagship of the slim line Intellivox DDC range. Its predecessor, the Intellivox-6c has been serving a wide variety of applications since its introduction in 1998 and has been installed in high profile projects all around the world. It has proven to be a versatile and accurate solution for all venues requiring excellent speech intelligibility under high reverberant conditions. With an array length in excess of 4 m the Intellivox-DC500 not only offers long throw capability but also greater control at lower frequencies. A single Intellivox-DC500 is capable of covering an area up to 70 m whilst maintaining an even sound pressure level. In order to achieve such outstanding performance the Intellivox-DC500 is equipped with a 32-bit floating point DSP (Digital Signal Processor) which handles the demanding mathematical calculations that are necessary to achieve highly accurate directivity control. In addition to this the DSP offers a wealth of useful audio processing features including: volume control, parametric EQ and delay. The thirty two, custom designed, 4” loudspeakers are driven by a sixteen channel class-D amplifier, power for which is provided 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 VA applications. The unit can be controlled using our proprietary WinControl software which offers user friendly control of the beam steering parameters, audio processing and surveillance features. The increased low-mid frequency control offered by the array makes the Intellivox-DC500 suitable for easy and unobtrusive implementation in very large, highly reverberant and architecturally sensitive environments.
