Audio-Technica has launched the AT-DMM828 Digital Matrix Mixer, the next generation of the company’s SmartMixer family of automatic mixers.

Unveiled 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. It increases clarity and audio quality, while providing instant, transparent switching between channels.

The mixer also offers a 'correlation' feature, which analyses and interprets redundancy of source material between channels in real time, and may in turn favor the dominant channel, simplifying the layout/output, as well as reducing feedback and phase issues.

The AT-DMM828 can be used with low-impedance dynamic or condenser microphones – including wireless microphone systems – along with line-level sources. Each of the eight balanced inputs provides switchable 48-Volt phantom power; attenuation is also selectable on each input to enable 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 – 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 linked mixers 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, such as Crestron or AMX, using 'open disclosure communication protocol' to control the mixer.
