Audio-Technica U843R

Audio-Technica U843R, a compact surface microphone with 3 cardioid capsules and 3 output channels, makes this microphone suitable for a wide variety of video and audio conference installations, especially when used with an automatic microphone mixer. The switches at the base of the microphone allow for easy reorientation of two capsules to switch between 360° or 300° coverage.

The ability to power/use the capsules individually adds a new level of flexibility. For example, if only 2 capsules are used, the microphone's characteristic becomes figure-of-eight or it can be used as a stereo microphone.

The microphone is shielded against radio interference through UniGuard® RFI technology.
