What it is
Summary
AI-generated from vendor-published content · May 31, 2026
This is a complete 12-person FM assistive listening kit built around Williams Sound's PPA R37N receivers, operating in the 72–76 MHz range. Each pocket-sized receiver picks up audio transmitted from a compatible Williams Sound FM transmitter (sold separately) and delivers it to the listener via the included surround earphones — making spoken content accessible for people with hearing loss in classrooms, houses of worship, tour groups, or conference settings. The hard charging case holds and recharges all 12 receivers simultaneously via NiMH batteries, which deliver around 32 hours of use per charge. The transmitter is not included, so you'll need to budget for a compatible unit like the PPA T46 to complete the system; this kit is the receiver side only. Also worth noting: FM systems in the 72–76 MHz band can be subject to interference in environments with dense wireless activity, and some venues may require FCC licensing considerations.

What Setup Looks Like
- Out of the box
- Charge all 12 receivers in the included case before first use — allow 16 hours for full charge.
- Distribute receivers to listeners and insert the included earphones.
- With a guide
- Pair receivers to a compatible Williams Sound FM transmitter (PPA T46, T45, T45NET, or T27) by matching frequency channels.
- Use channel-lock feature to prevent users from accidentally changing frequencies.
- Test audio levels and fit earphones or substitute neckloops for listeners who prefer them — expect 30–60 minutes for initial setup. See manufacturer support resources for detailed instructions.
- With professional help
- An audiologist or AT specialist can assess whether FM transmission fits the acoustic environment (room size, competing wireless systems, reverberation).
- For ADA-compliance installations in public venues, consult an assistive listening systems integrator to ensure proper coverage and receiver-to-seat ratios.
