Built for houses of worship requiring reliable assistive listening coverage across large sanctuary spaces, this complete RF system combines field-proven transmission hardware with rechargeable iDSP receiver technology. The integrated transmitter broadcasts across 72 MHz bandwidth to support up to six simultaneous systems, while eight included receivers feature DSP loop drivers for direct telecoil coupling and lithium-ion cells that eliminate alkaline battery replacement cycles.

The drop-in charging station streamlines pre-service preparation and post-service collection, mounting to walls, drawers, or rack enclosures for accessible dispensing. Engineered for institutions managing recurring services where consistent audio quality and simplified device maintenance directly impact congregant experience and volunteer workflow.

Included accessories—rack mount hardware, universal antenna kit, and earphone options—enable immediate deployment without supplemental purchases. The result is a fully contained listening solution that reduces setup complexity and operating costs while delivering broadcast-grade clarity for hearing-impaired attendees.
