The Telex AAT-2 is a dedicated assistive listening transmitter designed to broadcast clear audio from a sound source to personal receivers, promoting accessibility for individuals with hearing loss in public venues. It functions as a simple, reliable core component for compliance with regulations like the Americans with Disabilities Act (ADA), making it suitable for use in houses of worship, theaters, courtrooms, conference centers, and classrooms. The unit operates by accepting an audio input directly from a mixer, microphone, or audio player and transmitting it via a stable, license-free FM signal on a dedicated UHF frequency. This setup creates a personal listening zone where users with compatible receivers can hear the primary audio source—such as a speaker's voice, a soundtrack, or court proceedings—with enhanced clarity, free from the masking effects of background noise and distance.

Engineered for straightforward setup and operation, the AAT-2 features a compact, tabletop design with intuitive controls. It offers both microphone and line-level inputs, providing flexibility to connect to various audio sources, and includes gain adjustment to ensure a clean, distortion-free transmission signal. The transmitter utilizes phase-locked loop (PLL) synthesized tuning for precise, drift-free frequency stability, ensuring a consistent broadcast channel. A front-panel LCD screen clearly displays the selected operating frequency, output power setting, and audio level, allowing for easy monitoring and adjustment by facility staff without requiring specialized technical expertise.

Built for durability in permanent installations, the unit is housed in a robust metal chassis. It includes a telescoping whip antenna for localized coverage and provides connections for an external antenna to extend the broadcast range throughout a larger facility as needed. The AAT-2 is typically sold as part of a complete hearing assistance system kit, which includes multiple bodypack receivers. By delivering a direct, high-fidelity audio feed to personal receivers, the Telex AAT-2 effectively bridges the acoustic gap between a public address system and the hearing-impaired listener, fostering greater inclusion and understanding in shared auditory spaces.
