Audio-Technica Launches the AT-DMM828 Digital Matrix Mixer

	Audio Technica AT-DMM828 digital matrix mixer

Audio-Technica, a manufacturer of transducer technology for over 50 years, debuted its AT-DMM828 Digital Matrix Mixer, the next generation of the company's SmartMixer family of automatic mixers at InfoComm last week. The AT-DMM828 is a microprocessor-controlled, programmable, automatic-switching eight-channel matrix mixer. Designed for a variety of applications, including installed sound/sound reinforcement, houses of worship, broadcast, recording, and more, the AT-DMM828 is designed to improve audio quality through a number of sophisticated methods. One way it achieves this is by keeping the number of open microphones to a minimum, thus reducing background noise, feedback and other distractions, and increasing clarity and audio quality, while providing instant, completely transparent switching between channels. Additionally, the mixer features "correlation," which analyzes and interprets redundancy of source material between channels in real time and may in turn favor the dominant channel, simplifying the layout/output and reducing feedback, phase issues, etc.

The AT-DMM828 can be used with low-impedance dynamic or condenser microphones (including wireless microphone systems), as well as line-level sources. Each of the eight balanced inputs provides switchable 48V phantom power; attenuation is also selectable on each input to allow use with line-level signals. The mixer's outputs are balanced and non-inverting. All audio connections terminate in block screw connectors.

Up to 16 units of AT-DMM828's (a total of 128 channels of inputs) can be daisy-chained via CAT5e cable, which carries control bus, audio, and configuration data between mixers. Multiple mixers linked in this way will operate as if they are a single mixer. Therefore, microphones activated on any mixer will cause the appropriate switching functions to occur.

Each AT-DMM828 includes two separate external control system interfaces: Individual channel contact closures (via DB25 connector) and PC control (via RS232 connector or USB). The RS232 connector can also be used to connect an external third-party control system (e.g. Crestron or AMX) using "open disclosure communication protocol" to control the mixer.

The AT-DMM828 Digital Matrix Mixer will be available late summer 2013.
