PEL brings Bosch PA/VA upgrade to Celtic stadium - in easy phases

PEL Services has provided Celtic FC with a modernised Public Address and Voice Alarm (PA / VA) system, installed in phased, intensive stages, without disrupting the day to day activities of the stadium.


Following in depth consultation acoustic measuring and careful planning of phases, PEL Services provided Celtic FC with a modernised public address and voice alarm (PA / VA) system, installed in intensive stages, without disrupting the day to day activities of the stadium.


Celtic is the top football club in Scotland and its stadium, Celtic Park in Glasgow, regularly hosts big European matches to a maximum capacity crowd of 60,000.  The stadium not only hosts football matches, but also daily activities in the hospitality suite.  Replacing the crucial safety systems had to be phased to prevent disruption, taking advantage of the limited down time between football seasons.  This also allowed some efficient spreading of the capital expenditure budget implications too.


Crowd Noise Levels


Initially, PEL conducted acoustic measurements (crowd noise levels) during a capacity-crowd UCL match; it identified that crowd noise sound pressure level (SPL) can consistently reach 99dB (A) for at least 10% of the measured period and can reach 112-115dB (A) during goal celebration!

Sound Technology and Flexibility


Phases One and Two have now been completed, with Phase One covering the main existing analogue public address / voice alarm system being replaced with a Bosch Praesideo digital amplification and Netmax DSP control system for back of house, combined with an Electro-Voice (EV) speaker system and BSS BLU DSP processors controlling the main stadium bowl area.


Due to the overall size of the stadium, the decision was made to utilise the features of the Dante protocol, allowing all main audio components to pass audio over the existing Celtic IT Network infrastructure, monitored locally on site by Celtic IT and remotely by the PEL team.


This work has already improved output quality, despite the outstanding need to address speaker types and configuration in Phase Three. The new back-of-house racks not only increase audio power and quality of signal, they are more compact, more reliable and have power-saving characteristics which will save Celtic Football Club considerable energy expenditure.


System Design and Planning


In the design process, looking at a layout which has grown and developed successively in recent years, PEL’s experts identified and advised the Stadium Management on additional opportunities to enhance the visitor experience as a by-product of essential works. Phase Two has seen the temporary installation of the Match-Day system, which is used for pre-and-post-match entertainment.


David Howell of Celtic Football Club said:  “We have been delighted to work with PEL once again on a project which we feel has brought great benefits to the Club and our supporters.
