Williams Sound FM Plus Assistive Listening System FM SYSTEMS FM 558-24 PRO
Replaces FM 458-24 PRO.
The personal Williams Sound FM 558-24 PRO Plus assisted listening system – now with integrated Wi-Fi – has replaced the existing 558 systems for public venues. With an operating range up to 1000 feet, the FM Plus 558 is best for large venues where superior coverage and an OLED user interface where a higher feature set and visibility is required. Also, it includes eight preconfigurable frequency-allocated channels for simultaneous use. This complete turnkey solution includes 24 PPA R37N receivers, each featuring seekbutton channel selection with access to 17 selectable wideband frequencies between 72.1-75.9MHz. This system complies with 2010 ADA guidelines for hearing assistance and is covered by Lifetime Plus limited warranty. The PRO version features a coaxial cable and rack panel kit for professional installation.
