Sound amplification system for a sports complex

For centralized system management, it is recommended to install an audio matrix, such as Apart Audio AUDIOCONTROL 12.8, BSS BLU-100, Electro-Voice N8000, with which all options for routing a music signal to different zones with their own settings and volume control become available.

A microphone console located at the reception, connected via a twisted pair to the processor, allows you to send voice messages to one of the zones, to a group of zones or to all zones of the complex. Also, with the help of a microphone console and an expansion console connected to it, it is possible to control the selection of a signal source and volume settings in each zone of the system using pre-programmed buttons. The control of operating modes is duplicated using a wired remote wall control panel. The same control panels are located directly in each of the zones where background sound is required and in each hall where a local sound system is required. In each of the local halls, in addition, there are panels with inputs for local connection of microphones and music sources.


The combined players Apart Audio PCR3000RMKIII, Denon DN-300Z, which combine a CD/MP3/USB/SD/Bluetooth player, as well as an FM and DAB tuner, are offered as signal sources.

If only Bluetooth sources are needed, it is possible to significantly reduce the cost of the project by using non-serial versions of ALINP panels with a built-in Bluetooth interface, developed by our company and manufactured to order, instead of the proposed players.

The facility's sound reinforcement control system is programmable and customizable, taking into account the features and purpose of the premises. If desired, you can create a remote control system from computers and tablets via a wired or wireless network.

For integration with the fire safety system, an external digital priority module or an integrated dry contact in the mixer-amplifier is provided for notification.

The halls are equipped with case acoustic systems from different manufacturers: Electro-Voice, CVGaudio, Apart Audio, JBL. In bathrooms – ceiling loudspeakers are usually installed. In wet areas – acoustic systems with a higher IP rating.

In local halls, loudspeakers are connected in low-impedance mode, which provides greater sound pressure and signal intelligibility.

For the cycle hall, additional low-frequency systems are provided, active (with a built-in amplifier) ​​or passive, depending on the structure of the sound system and the number of amplifiers.

For sound amplification of the system and adjustments of the frequency response (amplitude-frequency characteristic of the musical signal) of the acoustic systems, high-quality audio signal power amplifiers are installed, with a digital signal processor DSP, which have the most modern system of digital processing and routing of audio signals in each amplification channel.
