The FM+ Intercom System uses the PPA T55 transmitter to deliver audio over FM and Wi-Fi from a single device.
Replacing the older T45 model, the T55 adds improved DSP processing, multiple digital audio input options, and an OLED display for quick setup and monitoring.
Each PPA R37 receiver is designed for simplicity. A single seek button allows users to scan and lock onto one of 17 wideband FM frequencies between 72.1 and 75.9 MHz. This minimizes user confusion and makes the system ideal for environments with rotating or first-time users.
Expandable by design, the system supports any number of listeners and meets 2010 ADA hearing assistance guidelines, ensuring consistent access to clear audio across a wide range of use cases.

R37 receivers are preferred when simplicity matters most. The seek-button design reduces user error and speeds up distribution, making them ideal for classrooms, courts, and public programs with frequent turnover.
While optimized for speech clarity, the FM+ Intercom System can handle mixed audio sources such as presentations or playback when connected to a mixer or sound system through the T55 transmitter.
The availability of 17 wideband FM channels allows installers to select clean frequencies and avoid interference, even in facilities where multiple assistive listening systems are operating.
Yes. Because the system is FM-based, it’s not tied to a fixed room configuration. Receivers can be reassigned and used wherever the transmitter signal is available.
No. FM transmission works independently of Wi-Fi. Wi-Fi is optional and only used if listeners want to stream audio on personal devices via the WaveCAST app.
Maintenance is minimal. Replace batteries as needed, store receivers properly between uses, and periodically confirm transmitter settings. No calibration or reprogramming is required for daily operation.
Yes. The included neckloops allow users with telecoil-equipped hearing aids to connect without earphones, supporting ADA accessibility requirements.
