Telex SR-50 SoundMate Single Frequency Personal Receiver

The Telex SR-50 SoundMate is a single-frequency personal receiver engineered for assistive listening applications. Operating within the 72 to 76 MHz frequency band — a range designated for assistive listening use in the United States — it receives audio from compatible Telex transmitters including the TW-6, AAT-2, PST-16, ST-200, PST-170, and ST-300. Its single-channel design prioritizes simplicity: users turn it on and listen, without the need to scan or select frequencies, which makes it well-suited for environments like houses of worship, courtrooms, lecture halls, and guided tours where ease of use is essential.

As a personal receiver, the SR-50 is designed to be worn by the listener, typically with an earpiece or headphones connected to its output. Its compact form factor keeps it unobtrusive during extended use. While the analog FM technology and fixed-frequency operation represent an older approach to assistive listening — newer systems may use digital signals, 2.4 GHz, or Wi-Fi — the SR-50 remains a reliable component within existing Telex installations. Facilities already equipped with compatible Telex transmitters will find it a cost-effective way to expand listener capacity without replacing their entire system.
