Intellivox DC280

Digitally Steerable, Self Powered, Loudspeaker Array

Digitally Steerable, Self Powered, Loudspeaker Array

The Intellivox-DC280 has proven to be a versatile and effective solution for vocal reinforcement within reverberant venues, offering excellent speech intelligibility even in demanding acoustic conditions. The Intellivox-DC280 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, 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 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-DC280 suitable for easy and unobtrusive implementation in even the most architecturally sensitive environment.
