Broadcast in the sports complex

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

Architecture of the sports complex

The acoustic properties of the room greatly influence the reverberation and consequently the speech intelligibility and clarity of the music signal are affected. Also, based on architectural data, the type and location of installation of speaker systems is 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 required reverberation time, which are accepted according to certain standards and norms.

Acoustic properties are subject to change using additional acoustic materials. The selection of additional materials, as well as their placement, is carried out through acoustic design, which is based on calculations in the special program EASE 4.4. In this program, it is possible to change the architectural features and selection of loudspeakers for the sound of spectator seats.

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

Purpose and structure of the sound system.

Typically, a fitness center requires background music to be played. To solve this problem with a small budget, it is possible to get by with a simplified set of audio equipment, for example, a mixer-amplifier with a playback function from a flash drive and speaker systems. When selecting speaker systems, it is important to compare the required quantity with the power of the amplifiers.

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

-microphones and radio systems;

-Mixer;

-processing of sound signals;

- sound processors;

- amplifiers;

- Acustic systems.

For this amount of equipment, a separate room for permanent installation, as well as an operator, may be required. In some options, you can exclude live control of the audio system and replace it with automatic control. Processors with automatic functions such as feedback suppression, automatic input level and audio line opening are quite capable of transmitting the audio signal from the microphone and the signal source.

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

Delivery and cost

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

different budgets. You should take into account the budget with the delivery time of musical equipment, and when creating the system, clarify 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 delivering the equipment to the site.
