Main Features:

- Industry-first automatic hand-sensing patented technology: the microphone automatically mutes 3 seconds after being set down (any direction, any angle), goes into standby mode after 5 minutes to save energy, and completely shuts off power after 15 minutes. It mutes instantly if dropped, effectively preventing noise from shocking the sound system—a brand-new concept in smart, automated wireless microphones.

- Brand-new audio circuit design: crisp highs, strong mid-lows, with perfect detail reproduction. Ultra-strong dynamic tracking allows seamless sound pickup from both near and far distances.

- Innovative digital guide-tone technology completely eliminates cross-channel interference in KTV rooms. Never cross-talk!

- Equipped with whistling suppression circuit, making setup easier.

- Automatic search for interference-free channels, easier installation.

- Maximum output volume can be freely limited, more versatile.

- Host can flexibly set usage counts.

- UHF band, PLL frequency synthesis.

- 100×2 channels, 250KHz spacing.

- Superheterodyne dual conversion design, very high reception sensitivity.

- RF section uses multi-stage high-performance dielectric filters, excellent anti-interference capability.

- First intermediate frequency uses a surface acoustic wave filter; second intermediate frequency uses a three-stage ceramic filter, greatly improving anti-interference performance.

- Specially designed mute circuit eliminates microphone on/off noise completely.

- Uses commonly available AA batteries, continuous use 6–10 hours.

- Unique boost design ensures declining battery power does not affect microphone performance.

- Ideal operational range up to 80 meters, suitable for various scenarios.

- Default configuration: LCD screen with blue backlight, aluminum alloy microphone body.

- Adjustable transmission power and squelch threshold; external squelch control knob on receiver rear panel allows flexible effective operating radius from 10m–80m.

- IR automatic frequency matching allows quick sync between microphone and receiver.

- KTV engineering model: 2 microphones, 1 host. Easily configures for 100+ KTV rooms, unique product structure, quick and simple maintenance.

Highlights:

1. Clear and transparent sound, delicate and elastic, warm voicing, easy to pick up.

2. 200 frequencies with digital guide-tone technology, effectively isolates signal interference.

3. Supports up to 100 sets simultaneously without cross-talk.
