Intellivox ADC Digital Directivity Columns


The JBL Intellivox ADC (Analogue Directivity Control) Mark II range is intended for use in 70V/100V Public Address and Voice Alarm (PA/VA) systems. As with other Intellivox products the ADC range has been designed to maximise listening comfort and provide highly intelligible speech reproduction even within difficult reverberant spaces. 

The revolutionary Digital Directivity Control (DDC) algorithm, pioneered by JBL’s Duran Audio group, was used to define a set of passive filters which has been precisely transferred into the analogue domain resulting in the ADC technology.

The Passive filter network provides time alignment for the individual drivers, equalisation of the complete array and creates a constant wavelength line source.

Each array consists of 6 carefully aligned 4” full range loud- speakers housed inside a tough steel enclosure. The specially aligned drivers are highly efficient and have an extended flat frequency response, providing natural and uncoloured repro- duction of both spoken word and background music.
