· 2-inch TFT color screen, intuitively displaying work content, with free switching between Chinese and English.
· Five-button control, featuring frequency shifting, feedback, and personalized equalization adjustment.
· Feedback with frequency shift, with 4 levels of frequency shift options.
· Each channel is equipped with 12 notch filters, frequency range 20-20KHZ, which automatically scan for and
suppress howling points.
· Equipped with a noise gate function, it can suppress weak noise interference in the system.
· Input compression function, which eliminates feedback and enhances vocal dynamics.
· The response time can be set to three speeds: fast, medium, and slow, making it more user-friendly.
