PA Audio System Design & Installation

INTRODUCTION

Indoor 5-a-side arenas in Swindon and Birmingham have recently undergone substantial face lifts, including state-of-the-art audio visual systems, new 3G pitches systems and facilities for a version of five-a-side football played on a smaller field and mainly indoors.

PROJECT

NAV were approached by long-term client The Media Group with a request to design and install a bespoke audio solution for indoor 5-A-Side Football venues in Birmingham & Swindon. Following a recent takeover, the owners of the venues decided to diversify their client-base and cater for a range of different scenarios for their football pitches & league programme, with a total of 10 pitches in Birmingham (spread across several halls) and 5 pitches in Swindon. Both existing sound systems were either broken or poorly implemented and required immediate upgrade to deliver background music and create the right ambience for the new client base. In addition, the system needed to be capable of functioning as a high-level foreground music system for large football tournaments and roller-derby’s, reproducing high-quality music & speech with excellent coverage for all areas.


In addition, the owners wanted ‘impact’ as customers walked into the venue and requested that the main entrance be placed on a separate audio zone, tying in with a newly installed projector and digital signage system, along with a further independent zone for the Bar area, where JBL Control 28-1 8” speakers have been deployed. The design allows for any of four sources to be routed to any zone desired and be controlled from a central location by non-technical staff; therefore it needed to be as simple to use as possible.


JBL’s purpose-designed AE Series was recommended — principally the AC2212/00 Compact 2-Way speaker, with 100° x 100° coverage, matched with JBL AC118S subs. Its specifications met the audio requirements, while providing the width of coverage necessary to cover much of the floor area — including three 3G pitches and four other pitches for the alternative five-a-side game over seven zones in Birmingham and four zones to include the arena, entrance and bar, in Swindon, where JBL AC599 speakers were also recommended to cover the four far pitches.


NAV used HARMAN’s latest HiQnet Audio Architect software for all required programming (including the Crown Amplifiers) making integration between devices seamless. Using Audio Architect, design of the control panel was simple and linked very easily to the BLU-100.


“Ultimately this led to two very successful installations and a very satisfied client, who commented on the systems excellent sound quality and its ease of use.”
