Product Description
Industry-first patented automatic hand-sensing technology with a landing mute function. The microphone automatically mutes within 3 seconds after leaving the hand and remaining stationary (works in any direction or angle when placed). It enters energy-saving standby mode after 5 minutes and automatically shuts down after 15 minutes, completely cutting off power. This is a brand-new concept in intelligent, automated wireless microphones.
- A completely new audio circuit architecture delivers crisp highs, powerful mid-low frequencies, and flawless detail reproduction. Superior dynamic tracking ensures effortless pickup at both near and far distances.
- An innovative digital pilot tone technology eliminates cross-frequency interference in KTV rooms—no more frequency clashes!
- Equipped with feedback suppression circuitry for easier tuning.
- Automatic interference-free channel scanning for hassle-free setup.
- Adjustable maximum output volume for broader adaptability.
- The host unit can flexibly set usage limits.
- UHF band, phase-locked loop (PLL) frequency synthesis.
- 100×2 channels with 250KHz spacing.
- Superheterodyne dual-conversion design ensures ultra-high receiving sensitivity.
- RF section features multi-stage high-performance dielectric filters for excellent anti-interference capability.
- The first intermediate frequency uses a SAW filter, while the second employs a triple ceramic filter, significantly enhancing anti-interference performance.
- Specially designed mute circuit eliminates popping noise during microphone power-on/off.
- The microphone uses widely available AA batteries, offering 6–10 hours of continuous use.
- Unique voltage-boost design ensures consistent performance even as battery power declines.
- An operational range of up to 80 meters in ideal conditions, suitable for diverse applications.
- Standard configuration includes an LCD screen with orange backlight and an aluminum alloy microphone body.
- Adjustable transmission power and squelch threshold. The receiver’s rear panel features an external squelch control knob, allowing flexible operational range settings between 10–80 meters.
- Infrared auto-frequency synchronization enables quick pairing between the microphone and receiver.
- Dedicated KTV engineering model: two microphones, one host unit. Easily supports 100+ KTV rooms with a unique structural design for fast and simple maintenance.
