Most churches are relatively spacious and need a carefully monitored sound system to ensure that the congregation in a specific church service get to hear the best of what the pastors and choir singers have to offer.That is why people wear their Sunday best in preparation for a good spiritual uplifting.

Some churches may opt to save costs by installing the sound system themselves and do away with audio consultants who may have specific expertise on setting up p.a. systems that suit a certain church.The music DJ or sound engineer must be flexible and alert to harmonize frequencies of vocal speeches and reproduction of musical performances either by artists doing live bands or church choirs.

People around the world are born with very different sound vocal chords and produce sound at different capacities. For example, a pastor may have a low voice and the audience may struggle to pick up the preaching therefore the sound engineer will be required to amplify the voice using a competent mixer which connects to the microphone.The reverse is true as a loud preacher will need a voice reduction not to irritate the congregation.

A sound system may also accommodate those with hearing disabilities who need compliant personal hearing systems. These systems may be in the form of a wireless in -ear monitor that can be made available for those with impaired hearing to listen to the preaching like everyone else.However, this would require additional investment by the church and this provision is rare especially with churches saving costs.

The P.A. system at a minimum normally includes a microphone (input source),either cordless or with a cord, with an appropriate stand ,a powered mixer amplifier with a considerable number of channels and loud speakers. Other systems include more sophisticated equipment such as preamplifiers, signal routers(that determine zones to which sound signals are fed), control and monitoring equipment.The acoustics, which is the total effect of sound in the church space, will surely dictate the arrangement of the equipment to get the best sound possible.

As a sound engineer, it is paramount that he or she is conversant with all the equipment assigned.This would mean having knowledge about connection of each equipment to the right channels to avoid electrical short circuits which can damage the expensive musical devices.The installation of the p.a. system should factor in audibility which is the achievement of a comfortable listening level.Another factor is the size of the space in the church which should be considered to accurately place speakers in certain spots to bounce off sound waves accurately and minimize interference. Moreover, the frequency response that reaches listeners must accurately represent the original music performance or speech.To achieve this, all audio components must be synchronized to contribute to harmonized sound frequencies therefore each device is important in its own capacity and needs to be original and of relatively high quality.
