Harman incorporates the Intellivox acoustic boxes to his audio portfolio Professional

Earpro has included in its supply of audiovisual solutions the acoustic columns JBL - Intellivox, suitable audio teams for centers of worship, Airports, train stations and other reverberant spaces.

After the acquisition, In October 2013, of the Dutch firm Duran Audio BV by the group Harman, Its range of intellivox acoustic boxes have joined the line of professional products of JBL by Harman that is distributed in Spain and Portugal by Earpro.

JBL-Intellivox acoustic columns is ideal for those spaces in which the intelligibility and direction factors of the beam are critical; that is to say, those spaces where vocal messages are issued but for their architecture, They have a high reverberation that hinders intelligibility.

In these cases, The sound beam of the acoustic box needs to be accurately oriented to directly influence the specific area that must cover. A good distribution of acoustic columns of the JBL-Intellivox series allows you to distribute and direct the power needed to cover the different listening areas. This improves the relationship between direct sound and reverberant sound, guaranteeing better intelligibility.

DDC, DDS y WinControl

DDC technologies (Digital Directivity Control), DDS (Digital Directivity Synthesis) and the Wincontrol software, that incorporate the JBL - Intellivox boxes, They are those that make it possible to control the vertical directivity pattern of the brand's columns and direct the sound where you need.

DDC multichannel technology provides each independent amplification and signal -signal process. This allows electronically manipulating the vertical opening and guidance of the beam. So, It is possible to maintain uniform coverage in the listening plane and divert the beam of those surfaces that provide unwanted reflections.

DDS technology offers the ability to synthesize the 3D radiation pattern required for each acoustic column and conforms to the specific needs of the space. This is very useful for the coverage of listening areas at different heights.

With the wincontrol software, the digital directivity parameters that define the vertical dispersion of the acoustic column beam can be manipulated, and its equalization is controlled, delay and volume.

JBL acoustic categories – Intellivox

The acoustic columns JBL - Intellivox are grouped into three categories: DC, DS y DSX. The first two have a width of 134 mm, a depth of 92 mm and are available at five heights: 1150 mm, 1800 mm, 2800 mm, 4300 mm y 5000 mm. The higher the column, More control can be exercised on its directivity. All of them incorporate speakers of 4 inches, Internal amplification and DSP. DC/DS models 115 include, besides, 2 Tweeters to extend the frequency response in acute.

DSX models have the same dimensions as those of the other two categories and include a small series of speakers to extend the frequency response up to 18kHz.

For an even broader frequency response, JBL-Intellivox has the DC/DS models 808 y 1608, which include speakers of 6,5 inches, and are the most suitable for programs that combine music and word.
