Overview

The Telex SR-50 SoundMate is purpose-built for assistive listening environments where simplicity, reliability, and compliance matter as much as audio quality. Operating on Channel A at 72.1 MHz — within the FCC-designated assistive listening band — the SR-50 delivers clean, intelligible audio to individual listeners in houses of worship, classrooms, conference facilities, and live event venues. The single-frequency, factory-preset design strips away RF complexity entirely: there are no menus to navigate, no frequency scans to run, and no pairing procedures to complete. When deployed alongside compatible Telex transmitters, it simply works — an important characteristic for venues where non-technical staff handle equipment distribution.

The receiver's form factor is designed for personal use, compact enough to be worn or held without intruding on the listening experience. Audio output through the headphone jack delivers sufficient clarity for speech and music reproduction in its intended applications — the signal chain is straightforward and clean within the constraints of the 72 MHz band. The SR-50's value is fundamentally operational: in multi-receiver assistive listening deployments, the absence of per-unit configuration means scaling from ten receivers to a hundred introduces no additional setup burden. For venues managing ADA-compliant assistive listening systems or communication support in live production environments, the SR-50 offers a proven, low-friction solution within the established Telex SoundMate ecosystem.

Frequently Asked Questions

What transmitters is the SR-50 designed to work with, and does it require any frequency matching at setup?

The SR-50 is factory-preset to Channel A at 72.1 MHz and is designed to pair directly with Telex TW-6, AAT-2, PST-16, ST-200, PST-170, and ST-300 transmitters operating on the same channel. There is no frequency scanning or pairing procedure — the receiver and transmitter are preset at the factory, which eliminates RF setup time in the field.

Is 72.1 MHz a licensed or license-free frequency for assistive listening use in the United States?

72.1 MHz falls within the FCC-designated assistive listening frequency band (72–76 MHz), which is allocated specifically for personal assistive listening devices and does not require an individual broadcast license for compliant use. This makes the SR-50 straightforward to deploy in public venues, houses of worship, and educational institutions.

What audio output does the SR-50 provide, and what headphones or earphones are compatible?

The SR-50 provides a standard headphone output for use with personal earphones or lightweight headphones. Standard 3.5mm or compatible earphone connections work with the receiver; audio level is controlled at the receiver for individual listener comfort without affecting the transmitter signal.

How many SR-50 receivers can operate simultaneously in a single space?

Because the SR-50 operates on a single fixed frequency (72.1 MHz), all SR-50 units in a deployment receive the same transmitter signal simultaneously. There is no practical limit to the number of receivers in use at once — each listener gets their own receiver tuned to the shared channel.

What is the typical operating range of the SR-50 in a real-world venue environment?

Operating range depends on the transmitter used and the RF environment, but 72 MHz systems like the SR-50 ecosystem are designed for typical venue-scale coverage — classrooms, conference rooms, small theaters, and houses of worship. Solid walls and metal obstructions reduce effective range, as with any RF assistive listening system.

Strengths & Trade-offs

👍 Pros

Factory-preset single-frequency design eliminates RF setup entirely — receivers work out of the box with compatible Telex transmitters on the same channel.
The 72.1 MHz assistive listening band is FCC-designated for this use, making deployment in public venues and institutions straightforward from a compliance standpoint.
Single-channel simplicity means there are no user-facing frequency controls to misconfigure — reliable for venues where non-technical staff distribute receivers to attendees.
Designed for a broad ecosystem of Telex transmitters, giving installations flexibility to choose the transmitter form factor that fits the source environment.
Compact personal receiver form factor is unobtrusive for individual listeners in live event and educational settings.

👎 Cons

Single fixed frequency means the SR-50 cannot be retuned if 72.1 MHz experiences interference in a specific venue — the only remedy is a different product or transmitter.
Compatibility is limited to specific Telex transmitter models; it does not function as a general-purpose RF receiver for other systems or frequencies.
No multi-channel capability means the SR-50 cannot support listening to different audio feeds simultaneously in multi-zone or multi-language deployments.
Assistive listening band (72 MHz) offers less spectral flexibility than UHF systems, which can be more susceptible to interference in congested RF environments.
