Comtek 75-a a great product

it has been probably ten years since my dad has been able to hear the the messages shared in church. after getting this he has been real excited to now be able to hear only what is being said by the speaker. this prevents all the distracting whispering or if there are children playing nearby from being heard. you do need to make sure the church has a transmitter, but with this model it will find the broadcast. this can also be used at public places that use transmitters.

Com-Tek PR-75A

When I first received my Com-Tek PR-75A, it wouldn't work with my Sony headphones. So I went back to your website and found some Com-Tek headphones that were advertised to work with it. They were not in stock at the time so you had the factory "drop ship" them to me and I got them within a few days. Yesterday I used them at church for the first time, and I could hear EVERY word that was spoken! Thank you very much!

By NEIL G.

it has been probably ten years since my dad has been able to hear the the messages shared in church. after getting this he has been real excited to now be able to hear only what is being said by the speaker. this prevents all the distracting whispering or if there are children playing nearby from being heard. you do need to make sure the church has a transmitter, but with this model it will find the broadcast. this can also be used at public places that use transmitters.

Let the Comtek PR-75A AutoSmart Tuning Receiver revolutionize your auditory experience. Operating within the 72-76MHz range, this innovative device is not only reliable but also user-friendly, making it a perfect companion for your BST-75/BST-50b/M-175 Transmitters.

Designed with a high-quality audio frequency response of 100Hz-10kHz, the PR-75A ensures a superior listening experience. Whether you're attending church services, school classes, or tour guide presentations, this receiver's AutoSmart-Tuning (AST) function effortlessly adapts to multiple programs.

One of its standout features is the automatic activation and initiation of the AutoSmart-Tuning process when the earphone is plugged in. This means the PR-75A receiver intelligently selects the nearest compatible transmitter and sets itself to the corresponding channel, eliminating the need for manual tuning.

For venues with multiple transmitters, the PR-75A's one-button tuning control allows the receiver to re-tune to a different compatible transmitter with ease. Moreover, the receiver can be programmed for a set frequency or a preset group of frequencies, which can be sequentially accessed using the one-button tuning control (Program B).

The PR-75A also offers a pro-audio EQ (Option P) for high fidelity operation, or a standard EQ that emphasizes speech intelligibility, making it an ideal choice for auditory assistance and other personal communication applications.

Experience the blend of durability, innovation, and high-quality performance with the Comtek PR-75A AutoSmart Tuning Receiver. It's more than just a receiver; it's a game-changer in personal auditory devices.
