Williams AV PPA R37-12 PRO – 12-Pack Rechargeable FM Receiver Bundle

Product Overview

The Williams AV PPA R37-12 PRO is a 12-pack rechargeable FM assistive listening receiver bundle built for venues that must issue receivers to audiences on demand while staying ADA compliant. The package combines twelve R37 FM receivers operating on the 72-76 MHz hearing assistance band with a CHG 3512 PRO twelve-bay drop-in charger, NiMH rechargeable batteries, surround earphones, and a heavy-duty carrying case. It is a turnkey receiver fleet for auditoriums, houses of worship, courtrooms, and conference facilities that already operate a Williams Sound wideband FM transmitter.

Product Description

Each R37 receiver in this bundle provides seek-button channel selection across all 17 preset wideband frequencies reserved for hearing assistance, and is compatible with every Williams Sound 72-76 MHz wideband transmitter — including the PPA T45, T46, and T27. Audio is digitally synthesized for clarity and frequency stability, and the 3.5 mm stereo/mono output jack accepts earphones, headphones, or neckloops for telecoil-equipped hearing aids, which keeps the system aligned with ADA assistive listening requirements.

For facilities staff, the operational advantages are in the charging workflow: receivers drop into the CHG 3512 PRO charger with their BAT 026-2 NiMH batteries installed, charge in roughly 16 hours, and deliver up to 32 hours of runtime per charge. A battery-saving sleep mode engages after about six minutes without an RF signal, and channel-lock prevents patrons from accidentally retuning units between events. The included copolymer transport case protects the full fleet for portable deployments across multiple rooms or campuses.

This bundle is the rechargeable counterpart to the alkaline-based PPA R37-20 20-pack receiver bundle. Browse the full Williams AV assistive listening collection at Creation Networks for compatible transmitters, neckloops, and replacement accessories.

Frequently Asked Questions

Which transmitters work with the R37-12 PRO receiver bundle?

The R37 receivers are compatible with all Williams Sound 72-76 MHz wideband FM transmitters, including the PPA T27 tabletop transmitter, PPA T45 rack-mount transmitter, and PPA T46 bodypack transmitter. A transmitter is required and is not included in this bundle.

Does this bundle satisfy ADA assistive listening requirements?

The receivers operate on the 72-76 MHz frequencies reserved for hearing assistance and support neckloops for telecoil-equipped hearing aids through the 3.5 mm jack, which helps venues meet 2010 ADA hearing assistance guidelines. Confirm your venue's required receiver and neckloop counts against current ADA seating tables.

How long does a full recharge take, and how long do receivers run?

The CHG 3512 PRO charges all twelve receivers in approximately 16 hours, and each receiver runs up to 32 hours on a charge with the included NiMH batteries — enough for a full week of typical service schedules between charges.

Can the receivers also run on disposable batteries?

Yes. A slide switch inside each battery compartment selects between NiMH rechargeable and AA alkaline operation, with up to 50 hours of runtime on alkaline cells, which is useful as a backup during long event days.

Can this system be used outside the United States?

The receivers are FCC approved for U.S. markets and also carry Industry Canada approval. The 72-76 MHz band is not authorized in all countries, so check local radio regulations before international deployment.

What warranty applies?

The R37 receivers carry the Williams AV Lifetime PLUS Limited Warranty; the charger is warrantied for 1 year, the case carries a limited lifetime warranty, and most accessories are covered for 90 days. Creation Networks supports the full Williams AV product line for commercial integrators.
