Leichhardt Public School
Masters Voice Technology delivered a complete Q-SYS school PA and bell system upgrade for Leichhardt Public School, restoring reliable paging, automated bell scheduling and priority emergency communication across the campus. The networked solution improves speech clarity, simplifies administration control and provides a scalable platform for future expansion.

Overcoming Failed Legacy PA Infrastructure
Leichhardt Public School required a complete redevelopment of its PA and bell system, not a minor repair. The existing infrastructure could no longer provide the reliable school-wide communication needed for daily operations, scheduled bells, manual announcements and emergency alerts.
The key challenge was to restore clear and dependable audio across classrooms, corridors, administration areas and outdoor zones while replacing failed legacy PA equipment with a modern, scalable system. The new solution also needed to be simple enough for administration staff to operate every day, while being technically robust enough to support safety-critical communication during lockdowns, evacuations and other urgent events.
Masters Voice Technology needed to design a reliable audio network that could support the school’s current communication needs and allow for future expansion across additional zones or buildings.
How the PA and Bell System Was Designed to Work
The system workflow was designed to connect school administration, paging zones, bell schedules, emergency controls and distributed loudspeakers into one simple operating process. Leichhardt Public School required a complete PA and bell system redevelopment after its legacy audio infrastructure could no longer support reliable school-wide communication. For a busy Inner West primary school, the system needed to do more than play bells. It had to support daily announcements, scheduled class changes, targeted paging, emergency alerts and clear audio coverage across classrooms, corridors, administration areas and outdoor zones. Masters Voice Technology delivered a modern Q-SYS-based school PA and bell system that restored reliable communication across the campus. The upgrade combined automated bell scheduling, paging zones, emergency override functions, Dante audio networking, commercial amplification and distributed loudspeakers into one easy-to-use platform for school staff.
Administration staff manage daily bells, lesson changes, special events and holiday schedules through an easy-to-use interface.


Staff can make live or pre-recorded announcements to selected buildings, individual zones or the entire school.
Lockdown, evacuation and all-clear messages automatically take priority over bells, music and routine announcements.


Dante networked audio, commercial amplifiers and distributed loudspeakers deliver clear, consistent sound throughout classrooms, corridors, administration areas and outdoor spaces.
The Solution
Masters Voice Technology replaced the failed legacy infrastructure with a modern Q-SYS school PA and bell system designed for reliability, simplicity and future expansion. The system brought paging, bell scheduling, emergency alerts, audio routing and staff control into one integrated platform.
Q-SYS was selected because it provides a flexible software-based control and audio processing environment that can be customised for school operations. For Leichhardt Public School, this allowed bell schedules, paging zones, emergency functions and staff controls to be configured around the way the school operates day to day.
The solution was supported by Dante audio networking, commercial-grade amplification and distributed loudspeakers to deliver clear, reliable audio across classrooms, corridors, administration spaces and outdoor areas.
Why these Technologies were Selected
Q-SYS was selected as the central platform because it could combine bell scheduling, paging, emergency alerts, audio routing and staff controls within one flexible system tailored to the school’s daily operations. Dante audio networking was used to distribute digital audio reliably across the campus while reducing the limitations of long analogue cable runs and allowing easier future expansion. Lab Gruppen Dante amplifiers were chosen to provide dependable commercial-grade power for multiple speaker zones, while TOA loudspeakers were used to achieve clear, consistent coverage across classrooms, corridors, administration areas and shared spaces. Together, these technologies created a reliable and scalable communication system that supports both everyday school activities and safety-critical announcements.
The Q-SYS platform provides the central control and processing layer for the school PA system. It manages paging, bells, audio routing, emergency alerts and staff control interfaces from one integrated platform. This gives the school a more flexible alternative to traditional single-purpose bell and PA systems. Instead of relying on separate hardware for bells, paging, tones and control, the system brings these functions into a unified audio and control environment.


Dante audio networking was used to support reliable digital audio distribution across the school. This allows audio to be transported over the network rather than relying on long analogue cable runs that are more exposed to interference, signal loss and future limitations. For a school environment, Dante supports flexible routing, scalable distribution and easier integration between buildings, amplifiers and audio endpoints.
Lab Gruppen Dante amplification was used as part of the Leichhardt Public School upgrade, supporting reliable audio distribution to speaker zones across the campus. The project material identifies Lab Gruppen Dante amps as part of the Leichhardt Public School solution.


TOA speakers were used to provide clear and consistent audio coverage across classrooms, corridors and shared areas. The Q-SYS school PA material describes TOA speakers as a reliable distributed PA solution for classrooms, corridors and shared spaces.
