• Storage: Store the mixer in a cool, dry place away from direct sunlight and extreme temperatures.

7. Troubleshooting

• No Sound Output:
  • Check all power connections and ensure the mixer is turned on.
  • Verify that main output faders and channel faders are raised.
  • Ensure speakers/amplifiers are powered on and connected correctly.
  • Check input gain levels for each channel.
• Distorted Sound:
  • Reduce input gain if the "Peak Signal Indicator" (PK!) is constantly lit.
  • Lower channel volume faders or the main output fader.
  • Check for damaged cables.
• Phantom Power Not Working:
  • Ensure the 48V phantom power switch is engaged.
  • Verify that the microphone requires phantom power and is connected via an XLR cable.
• Bluetooth Connection Issues:
  • Ensure the mixer is in Bluetooth mode.
  • Check that your device's Bluetooth is enabled and discoverable.
  • Move your device closer to the mixer to reduce interference.
• USB Playback/Recording Failure:
  • Ensure the USB flash drive is formatted to FAT32.
