Williams Sound PFM PRO Personal FM System

The PFM PRO Personal FM System reduces background noise and maximizes listening by wirelessly broadcasting a speaker’s voice, audio program or simultaneous mix for all participants to hear. It is ideal for classrooms, small group listening, employee training, consultations, or any environment where listening can be difficult. The system includes rechargeable batteries and a convenient drop-in changer.

Additional PPA R37 receivers can be purchased separately to accommodate additional participants. All microphone and listening options can be used for all hearing loss applications when selected appropriately.
