SmartMixer® eight-channel microprocessor-controlled, programmable,
automatic mixer. RS232 port for external control or computer control.
Rack-mountable design. Includes link cable, software and power cord. 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
- 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
- Equipped with two audio outputs (one balanced, one unbalanced) to drive amplification systems or other equipment
- Monitor headphone output with level control
- Basic functions are configured via front panel; detailed settings through SmartMixer Software
- Mounts in a single 19" rack space via integral rack mount
