Audio Technica AT-DMM828 8Ch Digital Matrix Mixer
The AT-DMM828 SmartMixer® latest addition to Audio-Technica’s family of automatic mixers. This digital automatic 8 channel matrix mixer is designed to provide automatic mixing functions for installed sound, house of worship, broadcast and conference applications. Engineered with intuitive, easy-to-use software GUI, the AT-DMM828 automatically keeps the number of open microphones to a minimum, bringing background noise and feedback under control and providing increased clarity and audio quality.
