OPPORTUNITY Y

To prepare for hosting the 2021 World Men’s Handball Championship, Cairo International Stadium needed to update the audio

systems in its Indoor Halls Complex.

 

SOLUTION

To provide high-quality sound  reinforcement and meet the International Handball Federation’s standards, Audio Technology

 

deployed a state-of-the-art HARMAN Professional audio solution.

 

The JBL speaker system met the International Handball Federation’s requirements, as well as our own high standards. The quality and clarity are excellent. We’re thrilled with the results.

CAIRO INTERNATION STADIUM, EGYPT

An extension of Cairo International Stadium, the Cairo Stadium Indoor Halls Complex is a multi-use facility featuring four Olympic-standard indoor sports arenas. Over two weeks in January 2021, the venue hosted the 2021 World Men’s Handball Championship in its 16,900-capacity Main Hall and 1,620-seat Hall 2. Although functional and visually impressive, the venue wasn’t designed with acoustic performance in mind, possessing

a long reverberation time which made providing intelligible sound reinforcement challenging. Additionally, the venue’s structural design limits the amount of weight that can be hung from the ceiling, creating the need for a lightweight yet a high-quality audio solution. Adding yet another challenge, the International Handball Federation (IHF) enforces a maximum sound pressure level (SPL) limit, as well as a mandatory minimum standard of speech intelligibility.

 

To overcome the venue’s limitations and meet the IHF’s stringent audio standards, event organizers turned to Audio Technology, a Cairo-based full-service provider of professional audio equipment. Audio Technology designed and implemented a full HARMAN Professional audio solution across both halls featuring JBL loudspeakers, Crown amplifiers, BSS signal processors, and Soundcraft mixing consoles.

 

“When we started the project, we were concerned that the hall would need to be treated because of a high reverberation time,” said Mario Abadee

 

r, Presales Pro Systems Head, Audio Technology.  “We suggested some materials that  would improve  this, but when we installed the speakers, what they heard was so impressive, they decided they didn’t need any sound  treatment after  all.”

 

In the Main Hall, Audio Technology Installed JBL VTX V20 three-way line array speakers on a circular truss hanging from the center of the room. With dual 10-inch  neodymium Differential Drive woofers in each  88-pound cabinet, the VTX V20 delivers a low-frequency response down to 60 Hz, eliminating the need for heavy subwoofers. In Hall 2, Audio Techn

 

ology hung four clusters of compact JBL VTX A8 line array  speakers with VTX

a complete frequency response. They were very pleased with the quality.

 

 

When playing music through the VTX A8, the organizers could hear

B18 subwoofers from a ceiling-mounted circular truss similar to the Main Hall. The combination of lightweight dual 8-inch  loudspeakers and powerful  18-inch  subwoofers provided the ideal balance of sound quality and power while staying within safe weight limits.  Both the VTX V20 and VTX A8 feature advanced, proprietary waveguides for broad, consistent coverage throughout both halls.

 

“We had to remove the subwoofers, and for that, we needed to use a larger Differential Drive in order to achieve the lower frequencies,” said Abadeer. “This was in the specs of the JBL VTX V20.  It’s a very, very impressive speaker. And, when playing music through the VTX A8, the organizers could hear a complete frequency response. They were  very pleased with the quality.”

 

In addition to the audience-facing VTX Series speakers, Audio Technology deployed four JBL AC2212/95 loudspeakers in each hall to provide sound coverage for the players and referees on the court.  With their wide dispersion angle, the AC2212/95 speakers ensured players could clearly hear instructions from officials, as well as the bell marking the end of each half.

 

To power the sound systems in both halls,  Audio Technology selected Crown I-Tech HD Series and DCi Network  Series amplifiers, which feature onboard EQ and delay for crystal-clear sound quality, as well as remote monitoring tools for convenience

and speaker protection. For precise control of sound  reinforcement, Audio Technology provided Soundcraft Vi1 and Si Performer 3 mixing consoles, which feature a variety

of flexible input and output options,  powerful  digital signal  processing capabilities and color-coded FaderGlow  technology for intuitive operation and visual feedback. BSS Soundweb London BLU Series networked signal processors provide flexible routing capabilities, allowing sound reinforcement personnel to easily configure and monitor the system.

 

 

 

 

 

“The Crown amplifiers already have the full preset for our speakers,” said Abadeer. “Through the software, you can see every circuit.  You have everything, and you can manage it from one place.  You don’t  need  to go through different software in order to check  the status of the system or the status of the amplifiers.”

 

The audio systems deployed by Audio Technology at the Cairo Stadium Indoor Halls Complex met and surpassed the IHF’s standards, providing clear, intelligible sound at safe sound pressure levels without the need for any acoustic treatment in the Main Hall or Hall 2.

“Hosting the 2021 World Men’s Handball Championship was an incredible privilege,” said Samir  Shawkey, Project Coordinator. “Going into the event, we wanted to ensure that spectators and players alike had the best possible experience. With the help of Audio Technology, we were  able to install a JBL Professional speaker system that  met the requirements of the International Handball Federation, as well as our own high standards. The quality and clarity is excellent. We’re thrilled with the results.”
