MX-381 8-Channel Intelligent Mixer
Intelligent Microphone Management & Gain Adjustment
Supports fast, noise-free microphone selection with automatic adaptation to changes in indoor background noise. Enables automatic gain adjustment when multiple microphones are activated, and the system can be cascaded to connect up to 512 microphones.
Professional Channel Adjustment & Status Indication
Each channel allows independent adjustment of high and low frequency equalization, equipped with channel activation and clipping indication functions. The peak-response output limiter supports threshold adjustment and LED indication, paired with active 48V balanced microphone inputs and auxiliary level inputs.
Stable Performance & Flexible Output
Features balanced XLR outputs and line outputs, with 34dB voltage gain output and a wide frequency response of 20Hz–20kHz. Boasts total harmonic distortion of <0.1% and supports wide voltage power supply of 100–240V, delivering clear and stable sound quality.
