Holy Innocents Primary School's newly installed Digitally Steerable Sound Beam Speaker System

Established in 1892, Holy Innocents’ High School was one of the first Chinese Mission Schools to be established in Singapore. In 1932, Holy Innocents’ Chinese Girls’ School was founded by Reverend Father Edward Becheras, Parish Priest of Church of the Nativity of the Blessed Virgin Mary. The school was then managed by Sisters of the Holy Infant Jesus.

1986 saw the last batch of graduands from the Chinese-medium school and the school became an English-medium school in 1987. With her history as a Chinese-medium school and her continual efforts in advocating bilingualism, Holy Innocents’ Primary School was designated as a Special Assistance Plan (SAP) school by the Ministry of Education in 1992.

Having experienced the benefits of digitally steered sound beam speakers previously with an installation deployed at the extremely reverberant(echo) indoor sports hall with great results, the school looked to the same technology when it came time to upgrade the sound system in the school hall.

A competitive and public ITQ was called for the replacement exercise.

Digitally steerable sound beam speakers offer many advantages over common speakers or even column array speakers. The ability to command the speaker to point the sound energy away from hard surfaces and towards the audience reduces the bouncing of stray sound energy from the back walls and ceiling thus improving the overall listening experience.

Sound pressure levels (volume) is also kept consistent with little difference between the first seat and the back of the hall and this means that the people sitting near the speakers do not suffer from high volumes.

Additionally, the school desired the flexibility to operate the new sound system in a reduced capacity when a simple public address is required. All this without having to access the control room and turn on the digital mixer. So, as part of the design, the system has the feature of being triggered from the wing of the stage via key switch located in a rack situated by stage right. The rack houses a compact analog mixing console, two Sennheiser EW100 G4-835 wireless microphones, DSP processor and the secondary power sequencer.
