Sport

The sports and leisure industry is one of the most demanding markets T. G. Baker (Sound) Ltd supplies, varying from sports centres to museums.

Sports centres themselves differ greatly in facilities and management, and therefore in sound and communication needs. Each area of a sports centre may require separate sound systems for a variety of different activities. Commentary in a sports hall, a gala in a swimming pool and music for aerobics or a restaurant can all function simultaneously. The system should also have the capability of integrating all of the areas for zoned Public Address or evacuation purposes.

The Time Capsule, Coatbridge

There is an increasing demand for leisure centres to have special effects for various themed areas, therefore increasing the intricacies of the system. However, T. G. Baker (Sound) Ltd has successfully installed a wide variety of such systems, most notably that of the Time capsule, Coatbridge.

Aintree

T. G. Baker (Sound) Ltd were asked to design, supply and commission a site wide, networked PA system to incorporate all of the existing stands and buildings, together with the complete design and fit-out of two new grandstands, Lord Sefton Stand and Earl of Derby Stand and a complete new Parade Ring complex.

The new PA system provides control and amplification for all of the existing permanently installed loudspeaker systems on the course, together with control and audio feeds to temporary amplifiers and loudspeakers used for the main Grand National meeting only. The system also distributes the sound for the on-course television channels to all bars and restaurants that have been provided with local amplification and control equipment. Audio signals to all areas are capable of being overridden by emergency paging microphones located within the Main Broadcast office and Police Control Rooms.

The system was designed using the latest Soundweb DSP based ‘BLU boxes’ and incorporates network hubs at three remote rack locations to enable local system operation of the system in the unlikely event of network failures in other buildings. As the PA system is critical to race-day operations, a dual-redundant fibre and copper network ring was installed between all network hubs to prevent any single-point failure from jeopardising the systems’ operation. Furthermore, a combination of stand-by batteries and UPS systems ensures that the PA system will operate in the event of power failure at full power for a period of one-hour with a three-hour standby.

High quality local sound systems are provided within each of the suites in the two new grandstands to cater for a wide variety of events, with each local system also including an infra-red system providing a dedicated audio signal for the hearing impaired.

Loudspeaker selection in all areas of the course was critical with the specification demanding high SPL (sound pressure levels) and speech intelligibility in all areas.

To meet with this challenging brief Electrovoice ZX1i 8” two-way weatherised full range loudspeakers were selected for installation around the perimeter of the new Parade Ring due to their sensitivity, weather-resistance and controlled coverage pattern with Premier Acoustic ceiling speakers, music horns, projection speakers and cabinet speakers serving all general areas of the two new Grandstands and new Broadcast Office building.

After extensive acoustic modelling using the latest computer aided software, Community R.5 full-range horn loaded loudspeakers were selected and installed within the two new Grandstands to cover the large terraced areas.

The resultant system has now withstood the rigours of three Grand National events, together with numerous other smaller race meetings and private functions with everyone concerned delighted with the new system.
