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 "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
