KV2 to announce VHD5.0 constant power point source array for audiences over 50,000
WORLD: Continuing its support for point source technology, KV2 Audio is to debut a new flagship system at Pro Light & Sound, named the VHD5.0. According to an official announcement from the company, the challenge for KV2 in building even larger point source systems for audiences of 50,000 people plus, was to reproduce the low mid energy that certain line arrays provide though the summing of multiple drivers, while maintaining the key benefits of point source technology, being minimal destructive interference in the higher frequency range and accurate impulse response.
The system builds on the principles also deployed in the VHD2.0 large format point source system, which can reportedly cater for audiences in excess of 10,000 people with just one or two enclosures per-side.
‘There is no doubt that the development of the Line Array was an improvement over the composite box type systems of the 1980s,’ commented director of sales Dave Croxton. ‘Having all components in a single axis array solved certain issues in respect to the combing problems in the horizontal plane but did not overcome the destructive interference occurring vertically and the loss of HF through air disturbance caused by wind and audience heat. Manufacturers have attempted to correct these problems in numerous ways both through acoustic design and DSP, however the end result has been further reductions in resolution due to the limitations of digital sampling rates and the simple principles of physics which cannot be ignored.
‘The focus seems to have turned to output rather than clarity. At KV2 we believe that definition equals distance and the higher the quality reproduction of the source, the better the intelligibility over distance. The theory that line arrays have less losses over distance than point source are somewhat irrelevant if the sound is not intelligible at the back of the venue. To achieve high definition we have focused on developing unique hybrid processing which takes the best technologies in both analogue and digital to advance speaker design to a whole new level. For instance, all of our time alignment of components, a crucial aspect of achieving optimum sound quality with any speaker design, is done at 20MHz using a proprietary PDM digital process that our engineers at KV2 have developed.’
‘On top of this we have focused on creating efficiencies in amplifier technology to deliver not just high headroom transient peaks, but sustainable high voltage output over time resulting in far better control and definition of bass frequencies. The design of VHD5.0 constant power point source array ensures that the radiated power of each bandwidth, handled by the various components of the system, is consistent and balanced in relevance to the overall frequency response. This ensures the sound remains the same in every seat in the house.’
