Part of the FM+ Assistive Listening Systems lineup from Williams AV, the FM 557-24 is a large-area Dual FM and Wi-Fi® assistive listening system that includes (24) FM R37 receivers.
This groundbreaking tech provides an industry-first choice of employing traditional FM receivers or using personal electronic devices over Wi-Fi for hearing assistance. Along with this versatility comes exceptional audio quality, as FM+ is assembled on a professional digital audio (DSP) platform. This technology is designed to support those who want to use their own smartphones and headphones for a more discreet assistive listening experience. Simplicity and flexibility is also available for those who prefer a more traditional assistive listening system with a dedicated FM receiver and headset. Now, venues willl no longer need to choose between providing FM or Wi-Fi assistive listening systems. FM+ supports the iOS and Android WaveCAST Apps as well as the Wi-Fi Receiver-- in addition to all of the current and legacy Williams AV FM receivers that operate on the 72-76 MHz bandwidth.
