Types of Systems
Assistive listening systems are generally categorized by their mode of transmission. There are hard-wired systems and three types of wireless systems: induction loop, infrared, and Fh4 radio transmission. Each has different advantages and disadvantages that can help determine which system is best for a given application. For example, an FM system may be better than an infrared system in some open-air assemblies since infrared signals can be overpowered by the sun; on the other hand an infrared system is typically a better choice than an FM system where confidential transmission is important. Recommendations: In selecting an ALS, consultation with professionals such as sound system consultants or contractors is often a good idea. No matter which technology is used, consider too that the quality of the system often determines the quality of the sound and transmission.
