Williams AV 20-pack FM R37 Receiver Bundle

The Williams AV PPA R37-20 is part of the Williams AV assistive listening range, the hardware that gets a clear feed of the room into a listener's ear when the loudspeakers alone will not do it.

Williams AV builds for install: the transmitters rack, the receivers charge in bays rather than one at a time, and the earphones and neckloops are replaceable parts rather than a sealed accessory. Ordered as part number PPA R37-20. Published dimensions, power and warranty are in the specifications tab.
