Features:
1. Superior feedback suppression circuitry prevents howling
2. Dual-mode reverb processing delivers richer, more natural, and transparent vocal effects; outputs front (rear) left/right channels, center channel, and subwoofer channel
3. Aluminum alloy panel with 1U slim design; card-style adjustment for effortless, streamlined operation
4. Microphone features six-band parametric EQ with wider adjustment range for smoother, more refined sound without compromising original tone. Enhances single-band audio quality and effectively suppresses feedback frequencies
5. Subwoofer output design with adjustable crossover point and output gain. Features comprehensive anti-feedback circuitry; when M1C mode is activated, the low-frequency signal output port automatically attenuates by half to prevent low-frequency feedback and equipment damage. Includes a function to prevent microphone signals from entering the subwoofer channel
6. Center channel output design allows selection between music/reverb ratio or pure vocal dry signal, with independent volume and high/mid/low frequency adjustment
7. Five microphone input channels: two on front panel, three on rear panel
8. Features Bluetooth audio input, optical input, and USB input
