KV2 Audio demo at Myer Music Bowl
- Details
Loading in at 7.00am, both systems were flown and ready for operation by 10.00am. Angus Davidson, technical director for Asia Pacific and North America was in charge of the set up. “It never ceases to amaze not just how quickly these systems go up but how little tweaking is required once they are in the air,” remarked Davidson. “Basically, once you get the height right it is simply a matter of adjusting the tilt angle, which on VHD5.0 can be done via remote control as the fly bar incorporates integrated tilt adjustment.”
A noise curfew was in place until midday, but everything was ready to roll as many of Australia’s leading sound engineers started to arrive to experience this new format in large-scale sound reinforcement. With the VHD5.0 Constant Power Point Source Array, KV2 has focused on creating a modular system that has minimal destructive interference while utilising multiple components in a small number of cabinets. VHD 8.10 Low Mid expansion boxes are arrayed around the VHD5.0 Mid High enclosure providing the headroom needed to deliver the low mids and keep the sound balanced.
The system is pieced together to represent one very large point source, each part of the system being proportional in size to the frequency wavelengths it reproduces. The radiated power of each bandwidth therefore remains consistent and balanced in relation to the overall frequency response. This ensures the same sound is delivered to every seat in the house, says the company.
“A number of engineers have commented on the system’s consistency in both frequency response and SPL in all parts of the venue but what has really impressed people is the intelligibility and coherent reproduction of the sound at the back of the venue well over 100 meters from the speakers.”
