Sutton Tennis club have chosen GSL to provide a solution to all there PA requirements. With a large facility on the outskirts of Sutton they already had an eight zone pa system that they use for many different applications, from general announcements to aerobics. Our engineer specified a Martin Audio AQ speaker system for one of their many halls, this povided the volume levels and sound quality required for a busy class and also remain descreet. Ecler amplification was used to replace some very tired ten year old amplifiers. A full service and some TLC saw the whole systems back to beyond it's former glory.
