JBL Intellivox H90 MkII

Overview

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 reproduction of both spoken word and background music.

The JBL Intellivox ADC-H90 Mark II is designed for use on platforms and in high ceiling corridors, to minimize spill over a large bandwidth outside the listening area. The precisely defined horizontal dispersion aims the acoustic signal at the listener area, whilst minimizing disturbance outside of this locality. This dramatically improves the listening comfort in surrounding areas of for instance, open platform railway stations.

The column is designed to be mounted horizontally and can be mechanically aimed according to desired throw.

The Intellivox ADC-H90 Mark II is designed to evenly cover distances up to 10-15 m. It has a fixed vertical dispersion of 130º and a horizontal opening angle of 30º. The focus point for the horizontal beam is at 15m.
