LANGPU ACT-W32 perfectly combines miniaturization and multifunctionality, still delivering a 262ft (80m) ultra-long transmission range. Whether for home karaoke, large-stage performances, or formal business meetings, it performs stably—proving its exceptional environmental adaptability.

Exceptional Sound Performance

Thanks to its innovative noise-reduction circuitry, this system delivers an impressive 105dB ultra-wide dynamic range, giving your voice a whole new level of depth.
From a soft whisper to a soaring chorus, every note is captured and brought to life, making your performance both delicate and impactful.

With a remarkable 105dB SNR, background noise is virtually eliminated, leaving your voice as pure and crystal-clear as it was meant to be.

Comprehensive Frequency Management

  • Auto-Scan

    One-click intelligent scanning of the surrounding spectrum environment avoids interference-prone bands, helping you quickly lock onto clear and usable channels efficiently.

  • Spectrum Analyzer

    Advanced spectrum analysis capabilities enable real-time mapping of RF spectrum for surrounding signal distribution.

    You can monitor and manage frequency usage like a professional audio engineer, optimizing your system's frequencies and coordinating channel allocation for nearby wireless devices to ensure no interference.

Smart Drop Protection - Mutes Instantly

The handheld microphone has a gyroscope sensor that constantly monitors device orientation. The system instantly activates mute mode to prevent noise through speakers when dropped. Even if accidents occur on stage, you'll never have to worry about harsh noise.

  • Auto-Sleep for Power Saving

    The microphone will automatically mute after about 3 seconds of inactivity and lower the screen brightness to enter
    power-saving mode, preventing battery drain and unexpected audio interference. Simply pick it up again for normal operation.

  • One-Touch Mute Control

    Mute your microphone with a single press of the power button - no menus needed. Whether pausing during performances, meetings, or whispering, you can immediately mute the mic . Press it again to swiftly resume normal operation, maintaining complete control.

  • Quick Channel Selection

    Across the UHF 640-690MHz band, each transmitter features 100 optimally selected frequency points (covering approximately 25MHz bandwidth), divided into 10 groups (each containing 10 frequency points).
    This grouping makes frequency selection easily - simply switch by group to lock onto desired frequency in seconds, avoiding the hassle of slight adjustment.

  • 2×1000 Frequency Points

    the ACT-W32 offers complete control over frequency selection - Each transmitter channel has 1,000 selectable frequency points across the UHF band (2,000 points total for dual channels), with ultra-precise 0.025MHz tuning steps.
    You can effortlessly select the ideal frequency in the complex RF environments.

  • 8-Level Receiver Sensitivity Adjustment

    8 adjustable sensitivity levels make you precisely control the microphone's receiving range.

    Lower sensitivity is suitable for close-range use, minimizing background noise interference, while higher sensitivity expands reception radius to maintain stable signals in large venues or long-distance scenarios.

    No matter the space size, achieve optimal audio.

4 Sound Modes

Pop – Enhances mid-high frequencies and moderate low frequencies in vocals, making the sound fuller and clearer, creating the unique atmosphere of pop music. 

Rock – Intensifies low frequency punch and high-frequency brilliance, emphasizing the power of drums and guitars to make rock performances more dynamic.

Classical – A flat and balanced response reproduces orchestral depth and spatial imaging, preserving the authentic character.

Jazz – Emphasizes mid-frequency details for a warm and relaxed atmosphere, showcasing the delicate and rich tones of jazz instruments.

Transmit Power Flexibility

Features dual power modes (5mW/20mW) to adapt to any environment.

5mW Low Power: Optimized for small space such as classrooms and meeting rooms to avoid power wasting for close-range reliability and battery life extension.

20mW High Power: Ideal for noisy large venues and outdoor events, ensuring long-range signal stability while minimizing interference.

  • Audio Output

    The ACT-W32 seamlessly adapts to your setup—whether connecting to a mixer or amplifier (requiring Mic-level output), or interfacing with cameras and recording devices (needing Line-level input).

    If you are unsure how to choose, the Line mode is recommended for it is compatible with most devices.

  • Pilot Frequency Anti-Interference

    Employs ID code digital pilot technology, with each device assigned a16-bit randomized ID.

    When multiple wireless devices are on the same channel, the receiver automatically identifies paired transmitters through ID verification—blocking all non-matching
    signals.

  • Performance Safety Lock

    The secret weapon against accidental activation in critical moments. With a single tap, all function keys are temporarily locked except volume adjustment and IR sync pairing.

    Even if buttons are bumped during intense performances, your settings remain perfectly unchanged—guaranteeing zero unexpected disruptions during important shows or meetings.

Unique Audio Stability Control System

PLL System(Phase-Locked Loop)

Acting as an autopilot for the wireless microphone frequency.

It continuously monitors the phase difference between the output signal and the reference signal, making real-time adjustments to the transmission frequency to ensure that the microphone output frequency remains closely aligned with the reference frequency without deviation.

In simple terms, PLL technology keeps your frequency "in tune".



Noise Locking Technology

No more worrying about sudden screeching noises during critical moments! This unique audio stabilization control system acts as your personal “audio guardian”.

When random electromagnetic interference or abnormal noise occurs, the microphone intelligently detects and blocks distortions before they reach the output.

Your audience will experience zero interruptions—just crisp and pristine sound, making every speech and performance more professional and seamless.
