Since the first appearance in the mid-to-late 1990s, the controllable speaker array expansion device has clearly entered the broadcast installation market. Its unique advantages have been applied to today's troublesome applications compared to traditional speaker systems. It can be seen that the products are constantly developing, emerging players enter the market, and new technologies have gradually matured.
Unless you have lived in a cave for the past 10 years, you should discover the unique phenomenon of speaker array devices. Probably you also know the unique properties that are designed for this device. But in case you really like a cave life, you won't know how much they play at this point. The first common problem is: fast steering array.
What is a controllable speaker array? As we all know, the controllable speaker array is: controllable column, digital controllable array, beam control system. An array of drivers (usually not always vertically aligned) is controlled by a series of digital signal processing.
The newest participant in the digitally controlled market is Tannoy. Details of Qflex began to spread. As more and more information emerges, it is clear that this is a huge challenge for established players. The company has been paying close attention to the limitations that competitor products consider. The first problem is pattern control. At present, a large number of products claim that the effective mode control frequency can reach 3 kHz. The Qflex product line offers good mode control with a frequency range up to 12kHz.
The second key difference is the controllable angle. Tannoy claims to offer ±70 degrees, an increase of ±30 degrees compared to recent competitors. The main advantage of this is that the column is placed at a higher ground clearance and may disappear further out of sight.
Tannoy is also using the latest DSP chip technology compared to its competitors. Since the latest Qflex technology includes later chip technology, the components of the DSP are cheaper. Obviously, once other players release the latest version of their products, this advantage will not last long, but at this point the company is still far ahead.
All of the controllable products on the market are very complex, and Tannoy claims that the frequency controllable range of its products is far ahead. One example is that all players rely on product-linked tools. DSP algorithms for controlling drivers are quite complex, and it is difficult for installers and system designers to describe, design, and tune systems without the appropriate software interfaces.
Tannoy chose to emphasize his own control and design software, which is really designed for less complex devices, with several columns that interact in limited fashion. If you want a full 3D model, you can export the data to the Qflex beam engine to ease it. The beam engine produced in the program is exported to the column of the DSP chip via Tannoy's VNet software.
