The microphone is really great. We hear no static nor other interrupting sounds. Works perfectly in our chapel

Fits the uni-pak perfectly. Clear sound and powerful.

The AT831cW is a great product. It works great, giving me the freedom to move about and still be heard. I am totally happy with the solution and at a great price.

I use this mic with an ATW-T1801 transmitter and an ATW-1801 receiver as one wireless system for video recording. The primary events are weddings and corporate events. The mic is a little bigger than I would prefer, and it is bigger than the mic that came with another ATW-1801 system that I have.

I use it to amplify a mountain dulcimer during live performance. I needed a unidirectional because the omnidirectional Shure I was using was prone to feedback.

18 July 2012

Replacement because the wires get wrapped around the transmitter by people trying to be neat and they damage the cable. Very nice to be able to just replace the mic w cable.

We use these mics for sound reinforcement in a wide variety of live events. They are simple, dependable, good-sounding microphones. However, the cord is a little fragile, but any cord this small is going to be fragile.

I replaced my AT-831b with this mic and have no complaints at all. The sensitivity and dynamic range are excellent and give me exactly the sound I'm looking for.

2 July 2010

This is the mic we got to go with the ATW 2110 body pack system we use at our church. It works great; very true sound, and unlike the mic we used to use, doesn't significantly lose sound level when he turns his head from side to side.

Nicely made and sound for the price!
