PA systems are designed primarily to help the congregation hear the spoken word: sermons, readings and testimonies - and music; both live and pre-recorded. Any PA system comprises key links in the ‘audio chain’, including input, control, amplification and output. Like a chain, any weak link will reduce the overall effectiveness of the system.
Unfortunately, Church sound reinforcement does not offer a ‘one size fits all’ type system. The many differing styles of building and the needs of congregations vary enormously. Understanding what you, as a church, would like to achieve with your PA system will enable you to make the right decisions when it comes to choosing. Key factors to consider are versatility and flexibility, and simplicity of use. For example, systems can be very simple to operate but not offer much in the way of flexibility, conversely, a complex system will be versatile but often require training to operate. These and many options in between influence the budget, so it is worth considering what you can reasonably achieve on a given budget. More money and equipment do not necessarily offer better sound quality without proper integration and training, but a very limited budget will inevitably produce limited results and can often be a false economy.
Hints & Tips:
Loudspeakers must offer carefully directed sound coverage to the congregation
Loudspeakers should be positioned forward of microphones to prevent 'feedback' loops (howling)
Choose the right microphone for the job – not all mics work the same way!
Ensure the PA operator is well-positioned to hear what the congregation can hear
System setup is at least as important as the equipment which comprises it
A sound system is only as good as its weakest link – e.g. poor mics will usually sound poor!
More microphones equal more potential for feedback (howling)
A good sound system will often go unnoticed by the listener!
PROs & CONs
Enhance the Worship – be heard!
Improve clarity of music/voice
Link other rooms e.g., crèche
Record services for distribution
Can be very easy to operate
Engage whole congregation
Listed buildings usually require approval (Faculty, etc)
Best solution may be beyond budget
Cheap ‘solutions’ can be worse than none!
Final thought...
Any Sound System is only as good as its weakest link – this includes product type, quality, setup, configuration and the experience of the sound operators! – If in doubt, ask!
