Naval Base Secondary School — Indoor Sports Hall Audio Upgrade

Energycon Engineering upgraded the audio system at Naval Base Secondary School’s indoor sports hall, replacing an outdated, muffled setup with a crystal-clear, plug-and-play system delivering powerful, consistent coverage for assemblies and sporting events.

The challenge

Like most school sports halls, the venue doubles as the assembly space — which means speech intelligibility matters as much as volume. The legacy system produced sound, but not clarity: announcements blurred together by the time they reached the far end of the hall.

The school needed a dependable replacement that its own staff could run for daily assemblies, PE lessons and inter-school events, installed without disrupting the school calendar.

The system we installed

How it was engineered

The system follows the same engineering approach we use across Singapore school halls: wall-mounted 12-inch passive Yamaha loudspeakers positioned for even coverage of the assembly area, a commercial power amplifier with proper headroom, and a compact analogue mixer that keeps operation to “switch on and speak”.

Consistent coverage — not maximum volume — was the design target. A hall where every student hears the same level is one where announcements are made once, not repeated.
