What is it? An eight-channel digital matrix mixer designed to provide automatic mixing functions for installed sound, houses of worship, broadcast and conference applications. Details The AT-DMM828 SmartMixer is the latest addition to Audio-Technica’s family of automatic mixers. Designed with an intuitive, easy-to-use software GUI, the AT-DMM828 uses selectable NOMA (Number of Open Mics Attenuated) circuitry to automatically keep the number of open microphones to a minimum, bringing background noise and feedback under control and providing increased clarity and audio quality. Eight balanced inputs allow connection of both mic- and line-level signals and provide individually-selectable 48V phantom power, individual gain and volume controls, adjustable gate attenuation and low-cut filtering (selectable via SmartMixer software) Compatible with Crestron and AMX systems, the AT-DMM828 incorporates RS232 and USB data ports to provide a connection point for PCs running the included SmartMixer software. External control over other devices is also possible via SmartMixer: Force-On and Force-Off allows an external contact closure to force its associated input to turn on or off. The design also offers VCA control to help limit feedback and a pre-select feature allowing priority of each microphone to be independently assigned. And another thing… Linking is possible for up to 16 AT-DMM828 SmartMixer units (up to 128 channels) each offering eight balanced audio outputs to drive amplification systems or other equipment.
