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 130 deg and a horizontal opening angle of 30 deg. The focus point for the horizontal beam is at 15m. This loudspeaker is EN 54-24 Compliant for life safety applications.
