G24-4 Wireless Microphone System 4 Channel for Stage Performance

Wireless Microphone Product Specifications (Simplified English Version)

Application: Optimized for live events, speeches and conferences.

Reception Stability: 4-antenna true diversity design with switchable dual-thread / antenna diversity modes. Built-in dual antenna

distribution and single-channel AB intelligent reception eliminates dead zones and ensures stable long-range reception without signal dropout.

Sound Quality & Anti-Interference: Strong anti-interference capability and wideband stable transmission. Professional sound restoration

with 30Hz–18kHz frequency response. Intelligent dynamic compression delivers clear vocal output with ultra-low noise in complex environments.

Frequency & Volume Control: Adjustable transmitter frequency and volume for performance, interview and conference scenarios.

Supports fast automatic frequency locking. 3 preset frequencies per channel (max 12 total) for flexible switching among handheld, lavalier,

headworn and conference microphones.

Channel Expansion: Switchable between 2-channel dual-thread true diversity and 4-channel antenna diversity modes.

Audio Gain Adaptation: Post-stage mixed output with adjustable high/low gain and attenuation, effectively matches various front-end devices,

reduces distortion and suppresses system noise.

Digital Processing & Security: Full digital wireless architecture with high-fidelity DSP processing and dual 32-bit digital encryption for stable and

secure signal transmission. Supports monitoring function.

Frequency Resources: 2/4-channel UHF wireless system with 2400 selectable frequencies. Built-in spectrum scanning avoids crosstalk and interference.

Power & Distance Adjustment: 3-level transmit power control, each level covering an extra 30–50 meters, easy for on-site installation.

Display & Operation: Dual 2.4-inch TFT screens display real-time status (frequency, battery, channel, signal switching, preset frequency, etc.).

Supports infrared auto-pairing and ACT auto frequency selection.

Microphone Compatibility: All-metal handheld microphone. Interchangeable microphones: 2 mics swappable in dual-thread mode;

4 mics swappable in antenna diversity mode. Mixed use of handheld, bodypack and conference units is supported.

Advanced Functions: Power memory for sequencer control, FBX howling suppression, real-time battery monitoring with low-power flashing reminder,

and mobile phone wave interference resistance.

Frequency Bands: Multiple UHF bands optional: 520–570MHz, 531–590MHz, 612–672MHz, 630–690MHz, 715–762MHz, 735–782MHz, 795–845MHz,

850–890MHz; 250Hz channel spacing (factory default prevails).

Stackable Channels: 15 units stackable (30 channels) in dual-thread mode; 8 units stackable (32 channels) in 1-to-4 antenna diversity mode.

Working Distance: 100–150m (dual-thread mode); 60–150m (antenna diversity mode). Touch key switch (default).
