Equipped with optional computer control, the AT-MX381 SmartMixer is the latest addition to Audio-Technica's family of automatic mixers. This microprocessor-controlled automatic mixer is designed to provide automatic mixing functions for installed sound, house of worship, broadcast and conference applications. Engineered for intuitive, easy-to-use operation, the new SmartMixer automatically keeps 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 use with both mic- and line-level signals
Each input provides:
-Phantom power (48V), individually selectable
-Individual gain and volume controls
-Gate attenuation (adjustable)
-Low-cut filter (individually selectable via SmartMixer Software)
- An RS232 data port provides a connection point for a PC with included SmartMixer Software
- Compatible with Crestron and AMX systems
- External control capability enables the SmartMixer to activate other devices
Force-On – allows an external contact closure to force its associated input to turn on
Force-Off – allows an external contact closure to force its associated input to turn off
Control Voltage Out – a voltage appears when the associated input's gate opens or turns inon in
- Selectable NOMA (Number of Open Mics Attenuated) circuitry helps control feedback
- Priority pre-select feature allows priority of each microphone to be independently assigned
- Last Mic On selectable for continuous room ambiance
- Linking capability for 16 units (up to 128 channels)
- A direct output connection is available for each input
