The Auditorium Infrared Sound System™ (ISS) transmits sounds to a wide variety of audiences with each person wearing a wireless HeartMan® Infrared Headphone. The ISS is available in two versions:
Single Three-Panel Infrared Array (1022477), recommended for smaller classrooms and auditoria of up to 175 seats
Dual Three-Panel Infrared Array (1022478), recommended for large auditoria of up to 500 seats
Because of the HeartMan® Infrared Headphone's comfortable binaural earpieces and the internal speaker, the sounds are like those heard with a stethoscope providing a realistic auscultation experience.
Quick user tips:
Raise array as high as possible for best transmission
