ALS is an amplification system utilizing transmitters, receivers, and coupling devices to bypass the acoustical space between a sound source and a listener by means of induction loop, radio frequency (FM system), infrared, or direct-wired equipment. 

Holy Trinity Lutheran Church has an FM system which is like a tiny radio station with its own frequency and has two parts. One part is a microphone that the speaker wears. The microphone sends a signal to a hand-held receiver with headphones worn by the listener. This allows the listener to hear the speaker's voice more clearly, independent of distance and background noise. 

Alternatively, individuals with hearing aids or cochlear implant that have Telecoils (T-coils) can connect to the FM system by selecting the "T" setting. T-coils, are small, discreet copper wires built into many hearing aids and cochlear implants. They act as a miniature wireless receiver, picking up magnetic signals from assistive listening systems, allowing audio to be directly broadcasted to the individuals’ hearing aid or cochlear implant. When the "T-switch" is activated on a person's hearing aid or cochlear implant, amplified sound is delivered directly to the individual's ear, reducing background noise and improving clarity. 

The sound level received can be controlled by both the receiver and hearing aid/implant processor volume controls.

To utilize HTLC’s FM system, please let one of the greeters know you would like a hand-held receiver and they will provide you with one to use during church service. If you have additional questions, please contact the church.
