True diversity one to two wireless microphone

True diversity one to two wireless microphone


◆ The main equipment includes a 4-channel true diversity wireless conference host and 4 square pole wireless conference microphones Features: ◆ Apply PLL frequency synthesis phase-locked loop technology to avoid interference frequencies; ◆ CPU bus control, combined with digital LCD interface display, allows for smooth operation and outstanding performance; ◆ Multi-stage narrow-band high-frequency and medium-frequency frequency selective filtering to fully eliminate interference signals; ◆ Audio compression and expansion technology, greatly reducing noise and increasing dynamic range; ◆ Feedback howling suppression and weakening function can effectively reduce feedback howling; ◆ The receiver adopts multi-stage high-frequency amplification and has extremely high sensitivity; ◆ Multiple noise monitoring circuits and a specially designed ID identification code verification system, making it super anti-interference; ◆ The ideal space usage range is 80 meters; ◆ You can choose any hand microphone, headband, or collar clip.
