Broadcast in the sports complex

The music broadcasting system of the sports complex is intended for background and speech accompaniment of events. At the stage of designing the broadcasting system, it is necessary to take into account many factors that affect the quality of the sound. The main factors that are worth paying attention to are listed below in the article.

Architecture of the sports complex

The acoustic properties of the room greatly affect reverberation and, therefore, there is an impact on the intelligibility of speech and the clarity of the music signal. Also, based on architectural data, the type and location of installation of acoustic systems are selected.

Reverberation time is the main criterion by which acoustic and electroacoustic characteristics are calculated. For any hall, you can find the required values ​​​​of the necessary reverberation time, which are accepted according to certain standards and norms.

Acoustic properties are subject to change with the help of additional acoustic materials. The choice of additional materials, as well as their placement, is carried out by acoustic design, which is based on the calculation in a special program EASE 4.4. In this program, it is possible to change the architectural features and the selection of loudspeakers for sounding the audience seats.

The combination of all architectural and acoustic properties creates a solution for high-quality acoustics of the hall, and can facilitate the selection of acoustic systems.

Purpose and structure of the sound system.

Usually, a fitness center requires background music broadcasting. To solve this problem with a small budget, it is possible to get by with a simplified composition of sound equipment, for example, a mixer-amplifier with a function of playing from a flash drive and acoustic systems. When selecting acoustic systems, it is important to compare the required number with the power of the amplifiers.

Equipment for a sports hall that requires microphones for announcements and several sources of phonograms will require an extended sound reinforcement system, which will include the following sound equipment:

- microphones and radio systems;

- mixing console;

- sound signal processing;

- sound processors;

- amplifiers;

- acoustic systems.

For this amount of equipment, a separate room for permanent installation and an operator may be required. In some cases, live control of the audio system can be excluded and replaced with automatic control. Processors with automatic functions, such as feedback suppression, automatic input signal level and opening of the audio line, will cope with the task of broadcasting the audio signal from the microphone and the signal source.

A mixing console with an operator will be needed in the case of athletes' performances, where there is also an award ceremony. In this case, a separate room is needed - a sound engineer's room and a room for amplification equipment.

Supply and cost

The same structure of the system for broadcasting and amplifying a musical signal for a sports facility can be created for a

different budget. It is necessary to take into account the budget with the delivery time of the musical equipment, and when forming the system, specify the cost of the equipment. In addition to the cost of the equipment, other economic factors are included, such as the cost of installation and the cost of delivery of the equipment to the facility.
