At ISTP, our philosophy is simple: clearly understand the challenges our clients are facing and provide solutions that are genuinely user-centric—systems that are easy, intuitive, and comfortable to use.
To achieve this, we take time to deeply analyze each inquiry, carefully study the environment, and develop the most suitable solution through thoughtful design and engineering. This project followed that same process, and we are proud to have delivered results that met the client’s expectations.

The existing analog system was outdated, and there were no specialists available who could properly manage it. As is common in many Catholic churches, the space suffered from long reverberation times, reduced speech intelligibility, feedback issues, and balance problems between the choir and spoken word. To comprehensively address these challenges, a Yamaha audio system was implemented.

The system is centered around a Yamaha MTX5-D audio DSP, processing 30 input and 16 output channels. Each of the four priests was precisely tuned to match their individual vocal characteristics, and the settings were saved as presets, allowing them to be easily recalled for each Mass.
PC406 amplifiers, SWR network switches, and a Tio1608-D2 I/O rack were installed at the headend. All Yamaha components are integrated via Audinate Dante, forming a complete network audio system. This approach minimizes signal degradation caused by multiple AD/DA conversions while providing flexible configuration options for both users and system engineers.





For stable and safe power integration, a 10 kVA AVR and a Kevler power sequencer were also applied. However, even the best hardware only reaches its full potential when paired with a well-designed user interface.

One of the greatest strengths of Yamaha’s network audio ecosystem is ProVisionaire software, which enables system design, configuration, control, and user interface development. Through ProVisionaire, the system was restructured to include only the functions truly needed by the users, making it easy to operate even for non-AV professionals. Carefully selected functions were programmed and applied to a custom template designed to match the church’s visual identity.





We sincerely thank St. James the Great Parish Alabang for choosing to work with ISTP, and we hope this new system wi
ll continue to serve and benefit many people for years to come.
