Purpose
The outdoor racetrack required an improved sound solution with directed sound towards the stands and team pit areas. Given the purpose of the track, the system needed to be loud enough to overcome the roar of the race cars.
Challenge
There were a few challenges the design team needed to study and develop a plan to overcome. First of which, the outdoor facility had a high ambient noise level that interfered with announcements. Additionally, the length of the racetrack and size of the sitting area for visitors required a high decibel level to be heard, whilst still maintaining an intelligible voice distribution. Finally, without ceilings the design needed to take select a type of speakers that can be installed on the poles which lined the stands.
Solution
The resulting design began by selecting over 30 SC-630T speaker horns that were installed high above the track on poles and directed towards areas of the stand, pits and common areas. The horns high wattage components were powered by DA-500 series power amplifiers to ensure enough power was cranked out. The system was controlled using the versatile M-9000 matrix mixer which provided plenty of control options and such as BGM, multi-zone broadcasting and several inputs sources options.
Feedback
The completion of the sound system overhaul was finalized with a thorough testing of the audio sound with various ambient noise, to recreate a live event. The owner of the facility was happy with the end product and the sound was noticeably clear and covered the entire facility.
