Places of worship
Places of worship are, nearly universally, very reverberant environments. Whether or not measures have been taken to improve the acoustic properties of the space, any PA system in an environment such as this has to be carefully designed to deal with reverberations and echoes.
We recommend to check the intelligibility of the PA system using the Bedrock SM50 STIPAmeter. The fact that intelligibility is sufficient at one specific point, does not mean that it is everywhere - careful evaluation is required, keeping in mind that acoustic conditions may change as a function of occupancy as well.
The Bedrock DSP500 is very well suited to carefully tune the PA system to the acoustic environment.
