The Intellivox-DS380 offers excellent speech intelligibility even in demanding acoustic conditions. The Intellivox-DS380 is capable of providing a constant sound pressure level over a distance of up to 45 m, although a substantial extension of this range can be achieved in less demanding acoustical conditions. The twenty, custom designed, 4" loudspeakers are driven by a sixteen 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-DS380 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.
