St Therese of Lisieux Church, Abergele

We take pride on our work, so it is always rewarding to receive compliments from our customers…

We have always had acoustic problems in our church. Last year [2013] we invited you to come and give us your expert advice on the problem. You suggested installing the Bose Professional Sound System and we accepted your advice and had the equipment installed. I must say it was a revelation. One parishioner said the it was the first time in 30 years that he had heard every word! It really has been successful. I must say I was impressed by the professional, but friendly way you conducted our business, always being on hand to listen and advise. I can certainly recommend this sound system to anyone who has had similar problems to ours and indeed to anyone looking for a new sound system.” Canon Bernard Morgan

The system included Bose ESP88 ControlSpace, Bose Panaray MA12EX line array loudspeakers and Audio-Technica microphones and a loop system.


Local church installation – a testimonial

Apple Sound have installed a new sound system at St Thomas church in Flintshire. The system includes Bose loudspeakers, Audio-Technica rechargeable wireless microphones and a loop system. Following the installation, we were delighted to receive the following note.

“Apple Sound have recently completed the installation of a Public Address and Loop System within St. Thomas’ Church, Flint Mountain, which was used for the first time on Sunday 22nd September 2013. I must congratulate Phil and his Team for firstly designing and then installing the system with the minimum of fuss and to a truly high level of professionalism. The wiring has been carefully placed out of sight wherever possible and the speakers strategically positioned to the extent that members of the congregation asked where they were located!! Finally upon completion the building was left tidy and ready for use. Congratulations to all.” David C Evans MCIAT and Rectors Warden, St Thomas.

Sound upgrade at All Saints Church

All Saints Church in Sale needed to improve sound quality for their growing congregation and contacted Apple Sound for advice. Bose line array loudspeakers were recommended to provide controlled distribution of sound to the congregation, in order to minimize reverberation in the large single-space church. Eight MA12EX line arrays were installed in four carefully positioned double-stacks, mounted with custom brackets, all in white. A Bose ControlSpace ESP88 digital processor provides tonal equalisation, delay alignment and automatic mixing – this leaves the system to look after the sound without the need for user adjustment. New hand-held and tie-clip radio microphones were installed – the Audio-Technica 2000 series was provided with drop-in automatic chargers.
