Concert Sound and Light

Concert Sound and Light

High-quality sound and light are the main criteria to assess the level of the event. Depending on the parameters of the hall and according to requirements of the customer, we will find the most efficient solution.

Concert Sound

Concert sound is one of the most conservative segments of the professional equipment market. Despite the large number of technical developments that are implemented into sound systems, time-proved technologies are used in many components. It is worth noting the widespread use of digital channels of signal transmission and processing that give flexible adjustability options and system operation. Acoustic components of the concert sound system often play a crucial role in obtaining of a high-quality sound signal in the all performed frequency range at all points of the premises where the sound is transmitted.

Depending on the room size the concert sound system can be set up in several configurations: 

Small multifunction halls

Along with other systems, the concert sound system can either be combined (for example, with the information display system), or be completely independent. The system may include active or passive acoustic systems, power amplifiers (if passive systems are used). Sound mixing board, functional features of which can correspond with the specifics of system’s usage, is always the main component of the signal routing. If necessary, the system can comprise of a set of signal processing devices (some types of signal processing can be built into the mixing board). Both fixed signal sources and musical instruments are used as signal sources.

Features of the system wiring enable to choose an optimum solution for each hall. In addition to its direct purpose, the system can be used for sound events of various formats. 

Medium halls

Higher requirements are often imposed on the equipment for such halls. On the one hand, the size of the hall (with good acoustic architecture) allows to count on the highest level of sound quality at all points of the hall, on the other hand, the desire to make it as functional as its “big brothers” is clear. In addition to higher power features and sound pressure characteristics, the dispersion and the types of the acoustic systems play an important role. The “source – remote control unit – processing – amplification – acoustics” line may be supplemented by additional equipment, and the signal can be also supplied to other rooms of the building. In these halls the interaction of all the systems of audio-visual means makes it possible to use all their capabilities as efficiently as possible.

Large concert halls

In large halls the sound amplification system is the most important. The use digital technologies of transmission, processing and routing of the signal is the most efficient here. The use of line arrays as the main acoustic system is currently the best for high-quality supply of the sound signal to every listener. Application of the digital mixing boards, either main or monitor ones, with the use of signal transmission over digital snake cable enables transmitting of a signal to amplification of the highest quality.

Concert light

Concert light equipment is one of the key elements during the concert shows. Concert light in the course of conducting large-scale events is no less important than the sound.

Several kinds of lighting devices can be distinguished among a variety of the ones used during the concerts: 

  • Dynamic lighting devices.
  • Static lighting devices.
  • Background lighting devices.
  • Decorative lighting devices.
  • Special effects devices.
This diversity of types of devices allows the lighting engineer to highlight the features of concert performances to the full extent. In addition, proper lighting of the stage and performing artists makes it possible to obtain a high-quality video image.

The use of full-circle projectors “heads” as basic dynamic devices significantly expands the technical possibilities for the construction of the light pictures. In case of low ceilings, scanners can be the basic dynamic devices. Projectors of various modifications designed for different power of lamps are used as static lighting devices. Multi-sectional blinders and stroboscopes of different capacities are used as devices giving dynamic flashes to emphasize the culmination points of the performance. Using follow spots enables the operator to focus the audience’s attention on the presenter or performing artist. Lasers that can diversify the light palette of images built on the lamp devices are often used in the light shows of the concert halls.

Increase of the impact of the lighting device operation is achieved by using generators of smoke, fog, snow, soap bubbles, heavy smoke and other special effects. In order to manage this equipment, control panels for dynamic lighting and floodlight are used. These functions are often combined in one device.

Usage of specialized software allows creating and managing the light concert program with the help of a personal computer. In order to work with static devices dimmer units are used, which are managed according to the DMX protocol as other devices.

Many devices are used as sources of light-emitting diodes having a number of advantages over the lamp devices. These devices are also widely used in concert light system.  

When considering the concert sound and light systems as components in the general system of a concert hall service, it is important to be able to use the full functionality with maximum efficiency.
