Cluster speaker systems, also known as monophonic systems, involve a system where all of the separate audio signals are mixed and routed together through a single channel. This allows all listeners to hear the audio at the same sound level. This makes it easier for church members to hear speech.
Surround sound systems, also known as stereophonic systems, have two separate channels for audio signals, which is best for church environments where there is a need to replicate the placement of instruments on a stage. This option is best for musical and performance pieces in the church.
A properly designed monophonic cluster system will be more beneficial to a greater number of people because it provides the same level of audio for all listeners. A church that plays a lot of music will benefit from the surround sound system.
