Item # FM 558
FM PLUS LARGE-AREA DUAL FM AND WI-FI ASSISTIVE LISTENING SYSTEM WITH 4 FM R38 RECEIVERS.
System Includes
(1) FM T55 transmitter
(4) PPA R38N receivers
(4) EAR 022 surround earphones
(2) NKL 001 neckloops
(1) IDP 008 ADA wall plaque
Includes AA Alkaline Batteries (BAT 001-2)
FM+ System Package (4 R38
receivers) / FM 558
The FM 558 system package is
a complete turnkey solution that includes 4 PPA R38 receivers and an FM+
transmitter for both FM and Wi-Fi transmission from the same box.
This system features the
cutting-edge PPA T55 transmitter (replacing the T45 FM transmitter) with
multiple digital audio input options and an OLED display with easy-to-manage
navigation and network control features.
Each FM R38 is a
multi-channel FM receiver with a high-resolution OLED screen. The receiver
comes with earphones and batteries but is otherwise identical to the PPA R38.
The R38 offers a quick view of receiver status and immediate entry to all user
settings. On-screen channel selection with easy access to 17 pre-set, wide-band
frequencies (72-76 MHz). The system is expandable, accommodating any number of
listeners. This system complies with 2010 ADA guidelines for hearing assistance
all for nearly the same cost as traditional FM systems.
Note: Firmware is model
specific
NOTE: The FCC requires
this device to be used with approved, FCC 15.203 compliant antennas and be
professionally installed. Refer to Williams AV’s Antenna Selection Install
Guide for compliant antennas for this product.
The FM + connects to the
installation location’s Wi-Fi Network. It does not provide a network on its
own. The Wi-Fi network will need to be installed and established before the FM
+ can be used.
