Audio Technica ATDM-0604a 6-in/4-out Digital Smart Mixer DSP

Description

Audio-Technica ATDM-0604a Automatic SmartMixer DSP

The Audio-Technica ATDM-0604a Automatic SmartMixer is a compact yet powerful DSP-based automatic mixer designed for professional installed audio applications where multiple microphones must be managed seamlessly. Ideal for meetings, conferences, courtrooms, education facilities, broadcast environments, houses of worship, and soft codec systems, it ensures clear, consistent audio without manual mixing.

Powered by Audio-Technica’s renowned SmartMixer® technology, the ATDM-0604a automatically balances input levels using either gain-sharing or gating modes. This intelligent processing prevents feedback, reduces ambient noise, and eliminates comb filtering while maintaining natural speech intelligibility across all active microphones.

The mixer provides six mic/line inputs plus one stereo input, along with two balanced outputs and one stereo unbalanced output, offering flexible connectivity for a wide range of installation scenarios. Each input channel includes advanced processing tools such as echo cancellation, 4-band EQ, compressor/de-esser, and feedback suppression, ensuring optimal clarity in demanding environments.

Comprehensive output processing includes a 12-band parametric EQ, compressor, and limiter for each output channel. Noise cancellation can be assigned to outputs, and eight feedback suppressors can be routed to inputs or outputs as required. The unit also supports Audio-Technica LINK connections for integration with compatible devices and ES954 hanging microphone arrays.

Configuration can be performed directly from the front panel for standalone operation or via web browser and Smart Mixer Manager software for advanced control. Remote operation over IP further enhances flexibility for permanent installations. Compatibility with Barco ClickShare Conference systems makes the ATDM-0604a particularly suitable for modern hybrid meeting environments.

With intelligent automation, powerful DSP processing, and reliable performance in a compact form factor, the ATDM-0604a is an ideal solution for professional multi-microphone installations requiring clear speech and minimal operator intervention.
