Darius and Girėnas Stadium features an RCF sound system

This building, which is presented as the first football infrastructure in Lithuania to meet UEFA requirements, It has one of the most powerful audio systems, complex and large-scale installed in the country. A solution that is based on the technology of Rcf.

The main sound system of the Darius Stadium and Girėnas Designed for maximum reliability, with full redundancy and a secure digital audio network. An infrastructure that has been made with the technology of Rcf.

This building has been recently opened and is the first football infrastructure in Lithuania that meets the requirements of the UEFA. Under the roofed grandstands, offers a capacity of 15.000 Seating and during concerts, can accommodate 30.000 people.

It is currently the largest closed concert hall in Lithuania, Capable of hosting even the most demanding concerts.

Audiotones subcontracted this project with its team of experienced professionals, Deploying entertainment, Evac sound systems, mechanisms of hoisting flags and large Led screens.

The protocols of Dante and AVB digital signal, ensuring easy integration of the internal sound system for concerts or other large events.

The stadium sound system is also available for main or auxiliary sound on most occasions.

The building houses five server rooms, with amplifiers located at the same distance. These technical rooms are connected by a quadruple fiber optic ring of digital audio links.. Ensures system stability: If any connection is interrupted, will continue to work without audible interruption.

In a stadium-like space, Interacting sound waves from individual acoustic systems must reach the listener simultaneously, thus improving overall speech intelligibility: STI (Speech transmission index).

Audiotonas engineers have programmed two different delay line scenarios that the operator can change at the touch of a button.. A total power of 96 kW feeds the 32 Speakers RCF P 5228-L in clusters of 4 modules each, installed evenly along the entire perimeter of the stadium.

The speakers RCF P 1108-T in 78 Additional lines of delayed sound provide coverage for the lower ring of the stands. Four units of extremely high power speaker systems were installed, RCF HL series, for field coverage. Studio monitors RCF AYRA serve the sound operator in the console position.

The frequency characteristics of all speaker systems were measured under real-world conditions using specialized measurement software and microphones.. Sound characteristics have been adjusted to eliminate unwanted resonance frequencies due to the acoustic environment of the stadium. This allowed, Not just get the best possible sound quality, but achieve the same tonal balance between various types of speakers.

The Audiotonas team measured sound pressures on the pitch, in the stands, in the upper and lower rings, providing perfect coverage and avoiding excessive sound pressure for the audience, maintaining ideal intelligibility. The sound system of the Darius and Girėnas stadium is one of the most powerful systems, complex and large-scale ever installed in Lithuania.

Evacuation and alarm
