Work Pro technology brings networked audio transmission to Salvador de Bahia airport

The installed solution includes more than 250 Speakers, a power amplifier, an audio matrix, 14 SPS8 and 14 DM microphones 115. All IP controlled via BlueLine Digital distributed audio system.

The specialist in professional audio projects Erhardt Projetos has relied on BlueLine digital technology from Work Pro, brand represented in Spain by Equipson, to bring network audio transmission to Luis E International Airport. Magalhaes in Brazil, also known as Salvador de Bahia.

These facilities have been equipped with this IP-based distributed audio system because it offers all the reliability and functionality that airport staff and passengers needed to hear important announcements clearly.

The airport is currently undergoing an extensive expansion and modernization program that is being carried out jointly with Actemium, a subsidiary of Vinci Énergies.

The first phase of the project was completed by the end of the 2019 and consisted of the expansion of the passenger terminal, the construction of a new pier with six boarding bridges, the installation of a new baggage handling system and new services for customers, including free and high-speed WiFi.

The task of ensuring communications connectivity at the new quay and between the old and new parts of the terminal fell to Erhardt Projetos, one of the largest professional audio and video companies in Brazil, Specialized in project design, equipment distribution, Digital Controllers and Integration Services.

Among the projects it has carried out in recent years are major infrastructure developments related to the Rio de Janeiro Olympic Games in 2016 and the World Cup in 2014, including Maracanã stadiums, Dunes and Gremio and the Olympic Water Stadium and the Olympic Velodrome.

“The sound system we installed was designed to support the operation of the new dock by allowing the dissemination of sound messages with a high degree of intelligibility. Covers several areas, including domestic and international arrivals and departures, The Document Inspection Area, the connections between the new quay and the old terminal and the complementary buildings. In addition to providing general assistance to passengers and staff, A key requirement of the sound system was that it should support the safety and operation of the airport premises, both in normal operating situations and in case of emergency and evacuation of the complex”, comments José Roberto Erhardt, Technical Director of the Company.

The solution chosen by Erhardt Projetos has included more than 250 Speakers, a power amplifier, an audio matrix, 14 Work Pro SPS8 and 14 DM microphones 115. All IP controlled via BlueLine Digital distributed audio system, consisting of 45 BLR stereo receivers 2 Lite MKII over AoIP and a BLS2 SD MKII AoIP stereo transmitter with a micro SD player.

José Roberto Erhardt chose the BlueLine Digital system because it is easy to design and quick to install, thanks to its user-friendly interface. Allows multiple audio channels to be transmitted and controlled over Ethernet, with very low latency, and transmission can be a simple case of linking from one point to another, or it may involve several points, or even a complete multi-channel system with alarm management control.

“It's an excellent solution, as it complements the robust audio distribution systems we use in our systems installations. We also like the fact that their configuration software is easy to use and has simple logic, which makes life much easier for the technicians who install it”, comments José Roberto Erhardt.

Likewise, adds that the support of Equipson and its distributor in Brazil, Discabos Group, was very efficient. “The BlueLine Digital system installed at Salvador de Bahia airport has been operating on a 24 hours of the day, 7 Days a week, without failures since its implementation a few months ago”.

Extra features

In addition to their general capabilities, there were some very specific reasons why this distributed audio system was ideal for the Salvador de Bahia airport project. These included:

One hundred percent IP with long distances between equipment racks and call station user points. Having a completely IP system was vital as it would have been very easy to use an analogue solution.
The modular nature of the system, which allowed the acquisition of the exact number of units needed. This resulted in a more cost-effective solution for the customer because it was cheaper than purchasing a complete system, All-in-one, where unused drives were wasted.
Having simple and intuitive software with systems management meant that integrators could customise their working environment.
Having a PoE power supply for each module made the organization of cables inside the rack cleaner and more organized, and released the rack strip doors.
