4. System Overview

The Williams AV FM 558 system combines FM and Wi-Fi technologies to deliver high-quality audio directly to listeners. It consists of the following key components:

• T55 Transmitter: This unit broadcasts audio signals via FM and Wi-Fi. It connects to your audio source (e.g., microphone, sound system) and transmits the sound to the receivers and Wi-Fi enabled devices.
• PPA R38N Receivers: These portable FM receivers pick up the audio signal from the T55 transmitter. Each receiver features a 3.5mm jack for connecting earphones or neckloops and controls for volume and channel selection.
• Ear 022 Earphones: Standard earphones designed for comfortable listening with the PPA R38N receivers.
• NKL 001 Neckloops: These inductive neckloops are designed for users with T-coil equipped hearing aids or cochlear implants. When connected to a PPA R38N receiver, they transmit the audio signal wirelessly to the hearing aid/implant.
