Bietrun Wireless Microphone for Singing, Karaoke, Streaming

Premium Wireless Karaoke Microphone: This wireless microphone features a built-in high-sensitivity professional dynamic microphone and an upgraded wireless range of up to 160 feet (50m). The Bietrun wireless mic offers outstanding signal stability, no delay, no radiation, anti-howling, anti-jamming, constant frequency, and less than 0.2% distortion. It also has 15 UHF adjustable channels to effectively avoid radio interference. The cordless mic is made of durable alloy material, making it harder, lighter, and more wear-resistant.

Plug and Play: The microphone can only be plugged into equipment with a mic input, not an AUX input, as it will not produce any sound. It is compatible with mic input speakers, singing machines, audio amplifiers, PA systems, mixers, voice amplifiers, and other streaming multimedia equipment. To connect to a PC, Apple iPhone, Android phone, or laptop, use a TRRS cable (USB-C to 3.5mm or Lightning to 3.5mm cable, not included).

Power and Display: The microphone does not come with any batteries, so you will need to use 2 AA Amazon Alkaline batteries. Ensure the batteries are installed correctly. The rechargeable receiver has a built-in 650 mAh battery that provides 4 hours of use time and can be fully charged in 3 hours. To power on the microphone and receiver, long-press and hold the respective buttons. The display will show the battery power and signal strength.

Unidirectional Microphone: The built-in professional moving-coil unidirectional microphone core is ideal for conferences, speeches, events, churches, family parties, open ceremonies, dancing instruction, and promotions. If you use multiple mics simultaneously or encounter noise, you can switch channels by opening the mic battery cover and pressing the "HI LO" button. Ensure each mic has a different channel number and that the channels are spaced apart.

Quick Troubleshooting: If you encounter any issues, follow these steps: 1. Ensure the mic and receiver have enough power. 2. Verify that the equipment is connected to the mic input, not other interfaces. 3. If you experience no sound from one or both mics, you will need to re-pair them: a. Turn off the receiver and mic. b. Open the mic battery cover. c. Press and hold the mic (HI LO) button for 10+ seconds until the display channel flashes. d. Quickly turn on the receiver, wait for the mic channel display to stop flashing, and the receiver's blue light should be solid, indicating it's ready for use.
