Main Features:

◆ Automatic hand-sensing technology: the microphone automatically mutes 3 seconds after being set down (in any direction or angle), enters power-saving standby mode after 5 minutes, and shuts down completely after 15 minutes, cutting off all power. It's a new-concept smart, automated wireless microphone.

◆ New digital pilot technology completely eliminates frequency interference between KTV rooms—never cross-talk!

◆ Equipped with a feedback suppression circuit for easier setup.

◆ Automatically mutes when dropped to the floor.

◆ Auto-search for interference-free channels, making installation easier.

◆ Maximum output volume can be freely set, suitable for a wide range of environments.

◆ Flexible settings for the number of times the unit can power on and password-protected startup.

◆ UHF band with PLL frequency synthesis.

◆ 100×2 channels with 250KHz channel spacing.

◆ Specially designed mute circuit completely eliminates noise when turning the mic on or off.

◆ Uses AA batteries, with 6–10 hours of continuous use.

◆ Ideal operating radius up to 50 meters, suitable for various settings.

◆ Default configuration includes an LCD screen with blue backlight and an aluminum mic body.

◆ Adjustable transmission power and mute threshold; the receiver’s back panel has an external mute control knob, allowing flexible effective operation radius from 10m to 50m.

◆ Infrared auto-tuning allows the microphone to quickly sync to the receiver’s channel.

◆ Easily configure over 100 KTV rooms; unique product structure makes maintenance quick and simple.

◆ Microphone color options: luxurious gold or gray.
