It sounds clear, has different channels which helps divide the receivers in different groups, when you have more than one transmitter, like I do. Review: Awesome sets for simultaneous translation or live tours. Tip- Check for local fm intereference - More than enough for light use, like interpreting at a wedding or church, doing a driving tour for guests. These worked flawlessly for live interpretation. The Lock feature helps users not chang frequencies, and neck strap is actually useful. Clear transmission within 15 feet as long as there are no obstructions or competing frequencies. At first out of the box we were disappointed with the hiss and static even at close range, but eventually we figured out how to get clear sound: 1) switch from stereo to mono; this made the most improvement and eliminated hiss 2) search for open frequencies. The default is 107.5, and our area is saturated at the higher fm stations, so we researched our local fm interference and reset to the bottom ranges and found a space where nothing was competing 4) make sure the venue isn’t also using fm for other mics. If so, find the band they use and avoid it. ## Features - The transmission distance of 30m in the open air; 1 broadcast can work with numerous fm receivers - Easy to operate; FM transmitter and receiver can be used by manually adjusting to the same frequency; with earphone for better listening environment - Translation system for church with 15 levels of transmit volume adjustable; small size; 7.87 x 5.91 x 1.18 inch; light weight and easy to wear - RP13 radio receivers support 5 station presets can manually store 5 favorite stations; with 24-hour digital clock; lock switch to prevent accidental operation - Long working time; the built-in lithium battery of TR503 FM Transmitter is 450mAh; which provides about 8h working time after 2-3h full recharge; receiver is power supply by 2 x AAA batteries (not included) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07W7QM1NW | | Antenna Location | Church translation | | Best Sellers Rank | #115,541 in Electronics ( See Top 100 in Electronics ) #136 in Car Audio FM Transmitters | | Brand | Retekess | | Built-In Media | Microphone, FM receiver, Earphone, Lanyard | | Color | Black | | Compatible Devices | Earphone | | Connectivity Technology | Auxiliary | | Connector Type | USB Type-C | | Customer Reviews | 4.2 out of 5 stars 93 Reviews | | Item Dimensions | 17.5 x 14.5 x 19.8 centimeters | | Item Weight | 848 g | | Manufacturer | Retekess | | Mfr Part Number | FY4430A-FY4305A10 | | Microphone Form Factor | Headset | | Model Name | FY4430A-FY4305A10 | | Model Number | FY4430A-FY4305A10 | | Number of Batteries | 2 AAA batteries required. | | Number of Channels | 17 | | Number of Items | 21 | | Polar Pattern | Unidirectional | | Power Source | Battery Powered | | Special Feature | one transmitter can work with numerous receivers | ## Product Details - **Brand:** Retekess - **Connectivity technology:** Auxiliary - **Connector type:** USB Type-C - **Model name:** FY4430A-FY4305A10 - **Recommended uses for product:** Church translation ## Images ![Retekess Church Translation System with 1 TR503 FM Transmitter Headset and 10 PR13 FM Radio Receivers, Listening System for Factory Museum School Church (1 Transmitter 10 Receivers) - Image 1](https://m.media-amazon.com/images/I/615UE7-YA4L.jpg) ![Retekess Church Translation System with 1 TR503 FM Transmitter Headset and 10 PR13 FM Radio Receivers, Listening System for Factory Museum School Church (1 Transmitter 10 Receivers) - Image 2](https://m.media-amazon.com/images/I/71eNVXBntdL.jpg) ![Retekess Church Translation System with 1 TR503 FM Transmitter Headset and 10 PR13 FM Radio Receivers, Listening System for Factory Museum School Church (1 Transmitter 10 Receivers) - Image 3](https://m.media-amazon.com/images/I/71nfPi5RS5L.jpg) ![Retekess Church Translation System with 1 TR503 FM Transmitter Headset and 10 PR13 FM Radio Receivers, Listening System for Factory Museum School Church (1 Transmitter 10 Receivers) - Image 4](https://m.media-amazon.com/images/I/71EKTh9HlqL.jpg) ![Retekess Church Translation System with 1 TR503 FM Transmitter Headset and 10 PR13 FM Radio Receivers, Listening System for Factory Museum School Church (1 Transmitter 10 Receivers) - Image 5](https://m.media-amazon.com/images/I/71LOnIPna3L.jpg) ## Questions & Answers **Q: What frequency range does the fm transmitter support?** A: Dear customer, Thank you very much for your question.
