System Features：

• Advanced Audio Architecture – Delivers refined highs, robust mid‑low frequencies, and outstanding detail reproduction.  
• Superior Dynamic Tracking – Maintains consistent pickup quality at both near and far distances.  

• Digital Pilot Tone Technology – Effectively prevents crosstalk between wireless systems.  
• Auto Scan: Quickly locate the optimal frequency to operate.
• IR Sync – Enables fast pairing of microphone to receiver; supports up to 6 simultaneous systems.  
• Adjustable Output Level – Flexible volume control for varied application needs.  

• Dual‑Conversion Superheterodyne – Delivers high receiving sensitivity.  

• Multi‑Stage RF Filtering – High‑performance dielectric filters for superior interference immunity.  

• Enhanced IF Filtering – SAW filter (1st IF) and 3‑stage ceramic filter (2nd IF) further improve noise rejection.  

• Pop‑Noise Suppression Circuit – Minimizes turn‑on/off thumps.  

• Battery & Power Management – Uses standard AA batteries (6–10 hours); boost circuit maintains stable output as battery depletes.  

• Operating Range – 100 m (standard), up to 300 m under ideal conditions.  

• Four LCD Displays – Real‑time status feedback on both transmitter and receiver.  • All‑Metal Housing – Durable construction with shock‑resistant elastic steel mesh grille.  

• One‑Touch Mute – Dedicated mute button on receiver prevents accidental operation.  

• Adjustable TX Power – Handheld models feature high/low power switch to match operating distance.  

Applications – Ideal for small to medium‑sized stages, classrooms, conference rooms, and similar venues. As this year’s key new product, it has gained strong market recognition.
