Maintenance

• Cleaning: Use a soft, dry cloth to clean the mixer's surface. Avoid using liquid cleaners or solvents, as they may damage the finish or internal components.
• Storage: Store the mixer in a cool, dry place away from direct sunlight and extreme temperatures.
• Handling: Avoid dropping the mixer or subjecting it to strong impacts.

Troubleshooting

No Sound Output:

• Check all cable connections (inputs, outputs, power).
• Ensure the MAIN VOL knob is turned up.
• Verify individual channel VOL knobs are turned up.

• If using phantom power, ensure it is activated for condenser microphones.

Distorted Sound:

• Reduce the GAIN knob for the input channel.
• Lower the individual channel VOL knob.
• Check the LED Peak Level Indicator; if it's consistently red, the signal is clipping.
• Ensure output devices (speakers, headphones) are not overdriven.

• Ensure the mixer is in Bluetooth mode.
• Check that Bluetooth is enabled on your device and "BM-07" is selected.
• Move your device closer to the mixer (within 1.5 feet).
• Try unpairing and re-pairing the device.

USB Recording/Playback Problems:

• Ensure the USB stick is properly formatted and contains compatible MP3 files for playback.
• Verify the USB stick has sufficient free space for recording.
• Confirm the correct USB mode (USB-A for stick, USB-B for computer) is selected.
