Audio-Technica introduces new automixer

At the recent Infocomm show in Orlando, FL, Audio-Technica introduced the AT-MX381 SmartMixer, a microprocessor-controlled, programmable, automatic-switching eight-channel automatic mixer. AT-MX381 features include eight balanced mic- or line-level inputs with individually selectable 48V phantom power, individual gain and volume controls, adjustable gate attenuation, and a low-cut filter.

The SmartMixer is equipped with Number of Open Mics Attenuated (NOMA) circuitry, which helps control feedback by compensating for increases in system gain. To custom-tailor conferencing needs, the priority of each microphone channel can be independently assigned, with three different modes of priority selection/operation. All audio connections terminate in block screw connectors for ease of installation.

External control capability enables the SmartMixer to interface with other devices. Three different modes are provided. Force-On allows an external contact closure to turn on an input, Force-Off allows an external contact closure to turn an input off, and Control Voltage Out turns on a voltage when an input’s gate is opened or activated.

Basic functions may be configured from the front panel. For more detailed configuration settings, the AT-MX381 can interface with a PC using its RS232 data port. SmartMixer Software can then be used to set up key operating functions. The AT-MX381 is also compatible with Crestron and AMX systems.

Up to 16 SmartMixers can be linked using the included Link Cable for large multi-mic installations with up to 128 channels. A direct output connection is available for each input for use with logging recorders and other devices. The compact AT-MX381 is rackmountable, occupying just a single rackspace.
