QS-1 Wireless Microphone Product Features
Industry-first automatic hand-sensing patent technology. The microphone automatically mutes within 3 seconds after being placed stationary (works in any direction or angle), enters energy-saving standby mode after 5 minutes, and automatically shuts down after 15 minutes, completely cutting off power. A brand-new intelligent and automated wireless microphone.
- New audio circuit architecture delivers crisp highs, powerful mid-lows, and perfect detail reproduction. Superior dynamic tracking ensures excellent pickup at any distance.
- Innovative digital pilot tone technology eliminates cross-frequency interference in KTV rooms—no more frequency clashes!
- 100×2 channels, 250kHz channel spacing
- Specially designed mute circuit eliminates popping noise when turning the microphone on/off
- Uses standard AA batteries with 6–10 hours of continuous use
- Unique voltage boost design ensures consistent performance even as battery power declines
- Operating range up to 60 meters in ideal conditions, suitable for various venues
- Default configuration includes LCD screen with blue backlight and aluminum microphone body
- Infrared auto-frequency synchronization for quick channel matching with the receiver
- KTV engineering-specific model: two microphones, one host. Easily configures 50 KTV rooms. Unique structural design for quick and simple maintenance.
