The FM 558 system package is a complete turnkey solution includes 12 PPA R38 receivers and an FM+ transmitter for both FM and Wi-Fi transmission from the same box.
This system features the cutting edge PPA T55 transmitter (replacing the T45 FM transmitter) with multiple digital audio input options and an OLED display with easy-to manage navigation, and network control features.
Each FM R38 is a multi-channel FM receiver with a high-resolution OLED screen. The receiver comes with earphones and batteries, but is otherwise identical to the PPA R38. The R38 offers a quick view of receiver status and immediate entry to all user settings. On-screen channel selection with easy access to 17 pre-set, wide-band frequencies (72-76 MHz). The system is expandable, accommodating any number of listeners. This system complies with 2010 ADA guidelines for hearing assistance all for nearly the same cost as traditional FM systems.
