Audio-Technica ATMX381
Automatic Mixer, 8 Channel

ATMX381

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.

Features

• 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 “on”
• 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
