LANGPU ACT-312 Wireless Microphone System offers an ultra-long 328ft (100m) wireless range and offers up to 200 selectable channels. Combined with an ultra-wide 102dB dynamic range and advanced mute technologies, it ensures professional-grade audio performance.

Exceptional Sound Performance

Thanks to its robust and stable analog circuit design, the LANGPU ACT-312 achieves an ultra-high 98 dB SNR, virtually eliminating any background noise and delivering crystal-clear, transparent sound.

Meanwhile, 102 dB wide dynamic range adds unprecedented depth and richness, ensuring stunning clarity and full-bodied texture from soft whispers to powerful vocals.

Simple Control Experience

  • Auto-Scan Technology

    The system intelligently analyzes surrounding frequencies and avoids all crowdedbands. It instantly selects the clearest frequency from 200 available channels- completely simplifying the process.

  • Performance Safety Lock

    Activate it with one tap to instantly lock all controls (except volume and IR sync), creating a safeguard for critical events.

Comprehensive Mute Protection

  • Instant Mute on Drop

    Built-in gyroscopic sensor continuously monitors device status. Even if accidentally dropped during a live performance, the audience will hear virtually no harsh impact noise and the performance will not be interrupted. Our advanced safety mechanism stands guard as your final failsafe.

  • Auto-Sleep Power Saving

     The microphone automatically mutes and dims its display after just 3 seconds of inactivity, activating power-saving mode. This smart function not only prevents unnecessary power consumption when idle, but also eliminates accidental audio leakage through the system.

    The system instantly reactivates the moment when lifted.

  • One-Touch Mute Control

    The microphone features convenient one-touch mute function. During performance pauses, meeting discussions, or private exchanges, effortlessly mute the microphone to prevent unintended sound transmission.

    Pressing the button again quickly restores sound pickup, putting you in complete control at all times.

Flexible Transmit Power Switching

Dual-Power Mode: The microphone transmitter features selectable 5 mW/20 mW output power for different usage scenarios.

 

High Power Mode (20 mW): Offers stronger signal penetration for stable long-range transmission, maintaining stability even at long distances or through obstacles with superior interference resistance.

 

Low-power mode (5 mW): Avoids unnecessary interference caused by overly strong signals while reducing energy consumption and extending battery life.

Noise-Lock Technology

The system intelligently detects and blocks random electromagnetic interference, preventing any aberrant noise from reaching the speakers.

More Flexible Options

Whether you're an educator lecturing in classrooms, a host presenting on stage, or an executive speaking in a meeting room, the LANGPU ACT-312 meet your needs through flexible microphone combinations. You can choose a bodypack transmitter with a lavalier mic for hands-free mobility. Alternatively, you can choose the conference mic, designed for round table discussions and board meetings, ensuring every word is clear and audible. This system delivers tailored audio solutions that precisely match your event's requirements.
