Harman adds intellivox speakers to its JBL Professional audio portfolio

Earpro has included in its offer of audiovisual solutions the acoustic columns JBL-Intellivox, audio equipment suitable for places 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 speakers have been incorporated into the line of professional products of JBL by Harman which is distributed in Spain and Portugal by Earpro.

The JBL-Intellivox acoustic columns are ideal for those spaces where intelligibility and beam addressing factors are critical; I mean, those spaces where vocal messages are emitted but that by its architecture, have a high reverb that hinders intelligibility.

In these cases, the sound beam of the speaker needs to be precisely oriented to directly affect the specific area it must cover. A good distribution of acoustic columns of the JBL-Intellivox series allows to distribute and direct the power that is needed to cover the different listening areas. This improves the relationship between direct sound and reverberant sound, ensuring better intelligibility.

Ddc, DDS and WinControl

DDC technologies (Digital Directivity Control), Dds (Digital Directivity Synthesis) and WinControl software, incorporating JBL–Intellivox boxes, are what make it possible to control the vertical directivity pattern of the brand columns and direct the sound to where it is needed.

DDC multichannel technology provides each channel of the acoustic columns with independent amplification and signal processing. This allows the vertical opening and orientation of the beam to be manipulated electronically. Like this, it is possible to maintain uniform coverage in the listening plane and deflect the beam from those surfaces that provide unwanted reflections.

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

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

Acoustic categories JBL – Intellivox

JBL–Intellivox acoustic columns are grouped into three categories: DC, DS and DSX. The first two have a width of 134 Mm, a depth of 92 mm and are available in five heights: 1150 Mm, 1800 Mm, 2800 Mm, 4300 mm and 5000 Mm. The higher the column, more control can be exercised over its directivity. All of them incorporate speakers of 4 Inch, internal amplification and DSP. DC/DS models 115 Include, In addition, 2 tweeters to extend in treble the frequency response.

The 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 wider frequency response, JBL-Intellivox has DC/DS models 808 and 1608, which include speakers 6,5 Inch, and are best suited for programs that combine music and speech.
