Dante turns Bristol Speedway into one of the largest live audio facilities in the world

The circuit offers high capacity and sound quality through Dante, after migration to audio over IP system, for the 165.000 spectators who come to see and feel the excitement of the Nascar races held there and throughout the complex.

Property of Speedway Motorsports, Bristol Motor Speedway, located in Tennessee (EU) hosts the most important races of the Nascar motorsport championship, where they go 165.000 Spectators waiting to experience the excitement of racing.

Precisely to enhance this last aspect with a different experience, Those responsible for the circuit have opted to deploy an audio network over IP Dante of Audinate, becoming one of the most extensive and complex live audio installations in the world.

As Josh Thompson explains, co-founder of event sound services specialist Point Source, hired to carry out the integration of audio systems and the acoustics of the venue, “given the unique demands of this environment, where high-pressure live events are held and where sound has to be distributed over long distances, There was only one digital audio networking platform that was up to this challenge.: “Audinate’s Dante audio over IP network”.

The PA system is made up of more than five hundred speakers that offer clear, quality sound, in which they are included from the national anthem, ambient music and announcements in the stands, rest areas and private spaces, and also reaches the perimeter of this extensive complex.

Thanks to the addressable IP network, multiple channels can be sent simultaneously along point-to-point routes and audio can be directed to individual speakers., speaker groups or all and these destinations can be modified on the fly.

In the event of an unforeseen incident or emergency, like a storm, lightning, a power outage or a car burning on the track, The track audio system becomes the best and fastest way to warn the crowd of danger and broadcast messages to protect them.

“We take this responsibility very seriously., so we chose a highly secure audio networking solution, configured with multiple levels of redundancy. “Dante has proven to be extremely secure and with very low latency”, assures Thompson.

Con 140 inputs and outputs, Bristol's Dante network integrates hundreds of components, as digital signal processors BSS Audio BLUE Dante, a digital audio mixer Yamaha with DM1000 analog/digital I/O box, Yamaha Dante-MY16-AUD and Yamaha TI01608A interface card for handling media inputs from analog sources, inter alia.

Another vital third-party component of the circuit's new audio system is the manufacturer's D-series amplification platform. Lab. The group, providing open and streamlined interoperability. Since amplifiers incorporate digital signal processing, Point Source did not need to purchase external DSP boxes, which in addition to a very important economic saving for the track management company, eliminated points of failure.

Numerous unDIO2X2 boxes are used as connection/disconnection ramps to the Dante network. Attero Tech, each of which allows two I/Os to be added instantly and easily to the network. Access is as easy as plugging a camcorder or other device into one of the many Attero Tech wall plates available throughout the facility.
