Product Overview

The Harmonai MX-381 8-Channel Intelligent Mixer is a smart audio management device engineered for professional conferencing and sound reinforcement applications. It provides 8 balanced input channels—each configurable for microphone or line-level signals—with independent volume control and gate attenuation level adjustment. Built-in NOMA (Number of Open Microphone Attenuated) technology automatically adjusts input gain based on the number of active channels, effectively suppressing acoustic feedback and ensuring clean, stable audio output.

The unit supports AUX input from third-party signal sources. Outputs include one balanced output and one 6.35mm unbalanced output, offering flexible connectivity with downstream amplifiers and processors. Channels 1–4 can be individually switched to priority preset mode (First-In-First-Out), and each channel group includes dedicated compression and limiting—delivering professional-grade audio management for complex meeting environments.

Typical Applications

The Harmonai MX-381 8-Channel Intelligent Mixer is widely deployed in large conference rooms, multi-function auditoriums, command centers, academic lecture halls, and government agency meeting rooms. Its NOMA intelligent gating technology is especially suited for meetings with multiple microphones in use simultaneously—automatically activating active channels while suppressing noise from idle ones. With support for cascading up to 16 units, it scales to manage up to 128 microphones, meeting the audio routing and mixing demands of ultra-large conference systems. Additionally, the unit is suitable for professional recording studios, front-of-house processing for live performances, and multimedia classrooms in educational institutions.
