Advantages | Disadvantages | |
Public Address (PA/speaker) | Reaches a larger number of people, good when many are not hearing ministry | Amplification may irritate some. Requires hand-held microphones and training in their use unless someone adjusts volume for each speaker |
Loop | Easy to use with any hearing aid with T-coils | Does not work when there is significant inductive noise |
FM or IR (infrared) |
More portable; transmitter can
be in another room The only private system (won’t transmit through walls); multiple systems are simpler to use |
Does not work if there is FM
interference from nearby FM transmitters
or electrical interference from within building or nearby towers Can be a little more difficult to set up; emitter panel must be in room |
Microphones Hanging or PZM Hand-held, lapel, etc |
More convenient Much more effective for hard-of-hearing people. Preferred option for PA or loops especially, ideal for those with moderate or greater hearing loss Both pick up extraneous noise as well as the room’s acoustical problems, such as echoes. |
Many do not want to hold or are unable to hold microphones while giving ministry. |
Mixer (may be included in amplifier) Automatic Manually controlled |
No personal attention required Preferred method in large meetings, such as YM, compensates for the difference in people’s voices, ignores coughs |
