RF Assistive Listening Systems
Wireless audio delivered straight to the listener. RF systems give guests with hearing loss clear, personal sound anywhere in your venue, with no wiring to the seat and no line of sight required.
What Is an RF Assistive Listening System?
An RF (radio frequency) assistive listening system sends the sound from your microphones, mixer, or AV system to portable receivers over a dedicated radio signal. Listeners wear headphones, earbuds, or a neckloop connected to a receiver and hear the program at their own volume, right in their ears.
Because radio waves pass through walls, seats, and people, RF systems work in auditoriums, classrooms, courtrooms, houses of worship, theaters, and even across multiple rooms or buildings. One transmitter can serve a single room or an entire facility.
Why Choose an RF System?
- Works throughout the room, with no seating restrictions
- Does not require line of sight, unlike infrared systems
- Personal volume control for every listener
- Easy to expand with additional receivers or channels
- Can cover multiple rooms or an entire building
How It Works
Audio from your sound system feeds a transmitter, which broadcasts it on a dedicated radio channel. Each listener picks up a receiver, plugs in headphones or a neckloop, and tunes to the channel. Guests with telecoil-equipped hearing aids or cochlear implants can use a neckloop to send the sound directly to their devices.
The result: clear, direct sound without background noise or reverberation.
Where RF Systems Excel
Large Venues
Auditoriums, sanctuaries, and theaters where listeners sit at varying distances from the stage.
Multiple Rooms
Facilities with several spaces, using separate channels so each room has its own program.
Portable Use
Tours, conferences, and events where a system needs to move or be set up quickly.
Retrofit Projects
Existing buildings where installing cable or a loop under the floor is impractical.
Why Venues Choose RF Systems
RF systems create a better experience for guests, students, and congregants who struggle to follow speech in a busy or echoing room. Listeners can sit anywhere, adjust their own volume, and stay engaged without asking for help.
For facilities, RF offers flexible coverage, straightforward installation, and a cost-effective way to meet accessibility requirements. Receivers can be checked out at a desk or usher station, and the system grows easily as your needs change.
Planning an RF System Installation
Every venue is unique, and a successful installation begins with a detailed assessment of the space, the existing sound system, and how your audience will use it. We help you select the right transmitter, receivers, and accessories, and plan for channel selection and signal coverage.
After installation, we provide testing, calibration, and documentation to ensure the system meets ADA requirements and performs reliably for years to come. Ongoing support is available whenever you need adjustments, upgrades, or additional areas.
Hearing Aid and Neckloop Compatibility
RF receivers work with standard headphones and earbuds, and with neckloops that send audio to the telecoil (T‑coil) found in most modern hearing aids and cochlear implants.
Pairing an RF system with neckloops gives listeners a choice of how they hear the program, making RF one of the most flexible assistive listening solutions available today.
