Love this unit. It has good range and a great sound. I use it in a large conference room and it works well. I love that the receiver is muted when the transmitter is turned off. Great product.

Much better than the AKG (which I wasn't happy about), which had tons of handling noise and picked up an interfering station. The PA speakers in our church are in the ceiling, so we just have to keep the gain down to prevent feedback. Other than that, it works well.

Used by a pastor to speak in a medium-sized hall. The range seems good, however, the sound went out during first use. Nevertheless, it has consistently worked since. It was probably user error. It was extremely easy to setup and use right out of the box.

Very good reception for our Church Play.Clear and brilliant speech and Talking ability. Clip it on a collared shirt and project your voice as if you were talking to 10 people and you will be very happy with the results.

The Audio Technica System 10 Digital Wireless with the Lavalier Mic works great in every situation I used it. No interference or dropouts, just a strong clean signal. No complaints what so ever.

The lapel mic system was purchased for our Church and is working out great. The sound is clear and the system is easy to use.

This unit works perfectly and I love it. When shopping for a unit, there were so many options but I didn't want to overspend. This has excellent range and I couldn't be happier. Excellent buy

I have several of these in use on our campus. They work as advertised and sound pretty good. We use them mainly for lecture halls and recording in smaller classrooms. The systems are set up with different mic options including hand held, lavaliere and ear worn mics.

This system is a real winner. Clear signal and when combined with the BP893 micro set hits a grand slam for a church service. Thank you Sweetwater and Audio-Technica!
