Setup Guide
1. Charging the Device and Microphones
Before first use, fully charge the karaoke machine and both wireless microphones. Connect the provided USB-C cable to the charging port on the speaker unit and each microphone, then connect the other end to a compatible USB power adapter (not included).
- The speaker unit's charging indicator will illuminate during charging and turn off when fully charged.
- For microphones, a red light indicates charging, and the light will change color or turn off when charging is complete.
2. Powering On
Press and hold the power button on the speaker unit until the indicator light turns on. Repeat this process for each wireless microphone.
3. Pairing Microphones
The wireless microphones are pre-paired with the speaker unit. If pairing is lost, ensure both the speaker and microphones are powered on. They should automatically reconnect. If issues persist, refer to the Troubleshooting section.
Operating Your Karaoke Machine
1. Bluetooth Connection
To play music wirelessly, enable Bluetooth on your smartphone, tablet, or other compatible device. Search for "LENRUE M65" (or similar name) in the Bluetooth device list and select it to pair. A confirmation sound will indicate successful connection.

2. TF Card and AUX Input
- TF Card: Insert a TF (microSD) card with pre-loaded MP3 music files into the designated slot on the speaker unit. The machine will automatically begin playing music from the card.
- AUX Input: Connect an external audio device (e.g., MP3 player, computer) to the AUX port on the speaker unit using a 3.5mm audio cable (not included). The machine will switch to AUX mode.
3. Volume Control
- Speaker Volume: Use the volume controls on the speaker unit or your connected Bluetooth device to adjust the music playback volume.
- Microphone Volume: Use the volume controls on each wireless microphone to adjust the microphone's output volume independently.
Important Note on Volume: The volume of songs played by the Bluetooth speaker does not affect the volume of microphone singing. You can adjust the music volume to cover the microphone sound if a user is shy, or increase microphone volume to exceed the music for an outgoing performance. To prevent sharp and strange sounds (sound feedback), avoid placing microphone heads too close to the speaker.
4. Voice Changing Effects
Each wireless microphone features a dedicated button to cycle through four magic voice effects: Baby, Monster, Male, Female, and Original Voice. Press the button repeatedly to select your desired effect.
