The pa system installed at the life guard towers at Sentosa beach (Singapore) is meant to be used for emergency announcements and playback of pre-recorded announcements to the visitors at the beach. The requirement of the system was that it needed to be operable on 12Vdc, as the towers are powered via Solar panels. There must also be intelligibility between the towers, which are situated approximately 100m from each other. The installer proposed the Apart MA35 mixing amplifiers with MPLT32-G horn loudspeakers and MICPACB-D microphones.The beach operation manager is very satisfied with the Apart audio system: "We experienced difficulties trying to find a suitable PA system that was operable with 12Vdc via Solar Power. The Apart MA35 meets our requirement aptly. The sound intelligibility of MPLT32-G powerful horn loudspeakers for all pre-recorded announcements is sufficiently audible in the open beach from tower to tower."
